Black Domina Seeds: Australia’s Ultimate Indica Powerhouse

by Jason Greenwood | Jun 26, 2025 | Cannabis Culture, Cannabis Education, seed collecting

Most people think they know heavy indica strains until they encounter Black Domina. This isn’t your garden-variety couch-lock cannabis—it’s a genetic masterpiece that redefined what potent indica effects could be. Developed by the legendary Sensi Seeds in the 1990s, Black Domina seedsrepresent four decades of selective breeding compressed into one devastatingly effective strain.

I’ve been around cannabis for over two decades, and Black Domina still commands respect. The name alone hints at its dominance—this strain doesn’t just relax you, it takes complete control. For Australian cannabis enthusiasts seeking serious indica genetics with reliable performance and knockout effects, Black Domina cannabis delivers everything you could want from premium genetics.

This guide covers everything from its complex four-way genetic heritage to understanding its effects and medical applications. Whether you’re dealing with chronic pain, insomnia, or simply want to experience what a properly bred indica can achieve, understanding Black Domina strain will change how you think about cannabis potency.

The Dark Genetics: How Black Domina Came to Rule

Black Domina seeds emerged from Sensi Seeds’ obsession with creating the ultimate indica experience. Rather than settling for simple crosses, they undertook something ambitious—combining four legendary indica genetics into a single, devastating strain.

The genetic foundation includes:

Northern Lights providing the backbone of resin production and stability
Ortega contributing intense physical effects and fast flowering
Hash Plant adding that distinctive hashy aroma and heavy stone
SA (South African indica) bringing unexpected vigor and unique terpene expressions

This 95% indica, 5% sativa combination creates something special. The tiny sativa influence prevents the complete catatonia that pure indicas sometimes deliver, leaving just enough mental awareness to appreciate the journey.

Why Sensi Seeds Called It “Black Domina”

The name reflects both the strain’s appearance and effects. Properly cultivated Black Domina cannabis develops deep purple-black hues that justify the name. The “Domina” part speaks to its commanding presence—this strain doesn’t negotiate with your tolerance or plans for the evening.

Sensi Seeds knew they’d created something extraordinary when early test grows consistently produced thick, resinous buds with effects that impressed even Amsterdam’s most jaded coffee shop patrons. The strain quickly earned recognition at cannabis competitions throughout the 1990s, establishing its reputation as serious medicine for serious conditions.

Black Domina’s Chemical Signature: Understanding the Power

Black Domina strain produces a cannabinoid profile that explains its legendary effects:

THC Content: 20-25% (some phenotypes pushing 28%) CBD Levels: 0.5-1.2% (higher than many modern indicas) CBN Content: 1.5-3% (contributing to sedative effects) CBG Presence: 0.8-1.5% (adding to the body stone)

The elevated CBN levels set Black Domina cannabis apart from other potent indicas. CBN forms when THC degrades, creating the drowsy, sedative effects that make this strain legendary for sleep disorders. Many commercial indica strains lack significant CBN, but Black Domina’s genetics naturally produce higher levels.

The Terpene Arsenal

Black Domina seeds produce plants rich in sedating terpenes:

Primary Terpenes:

Myrcene (40-55%): Creates the heavy body effects and enhances THC uptake
Caryophyllene (15-25%): Provides spicy aromatics and anti-inflammatory effects
Limonene (8-15%): Adds subtle citrus notes and mood elevation
Linalool (5-12%): Contributes lavender undertones and anxiolytic properties

The high myrcene content explains why Black Domina strain hits so hard. Myrcene acts as a potentiator, helping THC cross the blood-brain barrier more efficiently. Combined with the strain’s naturally high cannabinoid levels, this creates effects that feel disproportionate to the THC percentage alone.

Aroma Profile: Breaking apart quality Black Domina releases waves of earthy hash, followed by spicy pepper notes and subtle sweet undertones. The smell is unmistakably indica—deep, musky, and rich with the kind of complexity that only comes from proper genetic selection.

The Black Domina Experience: What to Expect

Black Domina strain effects unfold in predictable stages, making it reliable medicine for those who need consistent results.

The Onset (15-30 minutes)

Effects begin with subtle warmth spreading through the chest and shoulders. Unlike racy sativas that hit like a freight train, Black Domina cannabis announces itself gently. You’ll notice increased appetite and a growing sense of physical comfort.

The mental effects start as mild euphoria—not the giggly, social kind, but a deep contentment that makes everything feel manageable. Stress dissolves without dramatic mental shifts. Anxiety fades into distant memory.

Peak Effects (30 minutes – 2 hours)

The full Black Domina strain experience reveals itself during peak effects. Your body feels like it’s sinking into whatever surface you’re on, but in the most pleasant way possible. Muscle tension disappears completely. Physical discomfort becomes irrelevant.

Mentally, you remain present but deeply relaxed. Thoughts slow to a comfortable pace. The racing mental chatter that defines modern life simply stops. This makes Black Domina cannabis ideal for meditation, gentle creative work, or intimate conversations.

The Comedown (2-4 hours)

Rather than dropping off a cliff, Black Domina seeds produce effects that gradually fade into natural sleepiness. Many users report the best sleep of their lives after sessions with this strain. The transition feels organic rather than forced.

Medical Applications: Where Black Domina Excels

This is not medical advice. Anecdotally speaking, Medical cannabis patients consistently report success with Black Domina strain for specific conditions:

Understanding Black Domina’s Legacy

Black Domina strain represents a specific moment in cannabis breeding history—the 1990s intersection of landrace preservation with modern hybrid techniques. Understanding this context helps appreciate why the strain remains relevant decades later.

The Sensi Seeds Era

During the 1990s, Sensi Seeds led cannabis breeding innovation through systematic approach to genetic combination. Rather than random crossing, they analyzed specific traits from proven genetics and combined them purposefully.

Black Domina seeds emerged from this methodical breeding philosophy. Each parent strain contributed specific characteristics: Northern Lights provided stability and resin production, Ortega added intense effects and fast flowering, Hash Plant contributed distinctive aromatics and stone, while the South African genetics brought vigor and unique expressions.

This four-way approach required extensive testing and selection across multiple generations. Most breeders settled for simple F1 crosses, but Sensi Seeds stabilized Black Domina cannabis through careful backcrossing and phenotype selection.

Competition Success and Recognition

Black Domina strain earned recognition at major cannabis competitions throughout the late 1990s and early 2000s, most notably the 1st place award at the THC Cup in Valencia in 2011. These victories weren’t just marketing achievements—they represented validation from experienced judges comparing hundreds of entries.

The strain’s competition success came from delivering consistent, distinctive experiences that stood out from countless other indica varieties. Black Domina seeds produced cannabis that judges remembered and patients requested repeatedly.

Medical Cannabis Movement Impact

As medical cannabis programs developed across various jurisdictions, Black Domina cannabis found its niche among patients requiring serious therapeutic intervention. The strain’s high CBN content and complex effects profile made it valuable for conditions that lighter strains couldn’t address effectively.

Medical cannabis dispensaries consistently stocked Black Domina strain because patients specifically requested it for sleep disorders, chronic pain, and severe anxiety. This medical validation helped establish the strain’s reputation beyond recreational markets.

Breeding Influence on Modern Genetics

Contemporary cannabis breeders continue using Black Domina seeds in breeding projects, seeking to capture its distinctive effects and resin production in new combinations. The strain’s stable genetics and dominant traits make it valuable for adding indica characteristics to hybrid projects.

Modern “Cookies” and “Gelato” genetics might dominate current markets, but serious breeders appreciate Black Domina cannabis for foundational breeding work. The strain provides genetic stability and proven performance that trendy genetics often lack.

Preservation Efforts and Genetic Banking

Several organizations work to preserve authentic Black Domina strain genetics through seed banking and mother plant maintenance. These preservation efforts ensure future access to original genetics as commercial breeding moves toward high-THC, fast-flowering varieties.

Genetic preservation becomes increasingly important as cannabis legalization expands. Black Domina seeds represent breeding achievements that modern techniques might struggle to replicate without access to the original parent genetics.

Common Questions About Black Domina

Cannabis Seed Myths Debunked: Separating Fact from Fiction

by Jason Greenwood | Mar 24, 2025 | Cannabis Culture, seed collecting, seed storage

Key Takeaways

Cannabis seed viability isn’t determined by appearance or floating tests alone
Genetics play a more significant role in plant outcomes than growing techniques
Feminized seeds are not inherently weaker or less stable than regular seeds
Proper storage can maintain seed viability for 5+ years under optimal conditions
Seeds from the same strain can produce plants with varying characteristics

In the rapidly evolving cannabis cultivation landscape, misinformation about cannabis seeds spreads as quickly as the plants themselves. Whether you’re a commercial grower, home cultivator, or simply curious about cannabis horticulture, understanding the truth behind common seed myths is essential for making informed decisions. This article separates scientific facts from persistent fiction surrounding cannabis seeds, genetics, and industry marketing claims.

Myth #1: You Can Judge Seed Quality by Appearance Alone

Many cultivators believe they can determine a seed’s viability and genetic quality simply by examining its appearance. This myth suggests that dark, tiger-striped seeds are superior, while pale or greenish seeds are immature and worthless.

The Reality: While appearance can provide some basic information, it’s far from definitive. Research from agricultural universities shows that:

Seed coloration varies naturally between strains and phenotypes
Some perfectly viable seeds may appear lighter or lack tiger striping
Properly matured seeds come in various colors from light tan to nearly black
Immature seeds tend to be soft and easily crushed, regardless of color

The definitive test of a seed’s quality is whether it germinates successfully and produces a healthy plant—not how it looks. Internal genetic quality simply cannot be determined through visual inspection.

Myth #2: The Float Test Accurately Determines Seed Viability

A common practice among growers is placing seeds in water and discarding those that float, based on the belief that floating seeds are non-viable.

The Reality: While the float test can provide some indication of seed density, it’s not a reliable method for determining viability. Research demonstrates that:

Some viable seeds may float due to their natural composition
Some non-viable seeds may sink due to water absorption
Various cannabis strains naturally produce seeds with different densities
Environmental factors during seed formation affect density

More reliable germination testing methods include proper germination in quality growing medium or using standardized paper towel germination procedures under controlled temperature and humidity conditions.

Myth #3: Growing Techniques Matter More Than Genetics

A persistent myth suggests that with the right growing techniques, nutrients, and equipment, any cannabis seed can produce exceptional results.

The Reality: While cultivation practices are undeniably important, they can’t fundamentally transform genetic potential. Scientific breeding studies confirm that:

Genetic factors determine 70-80% of a plant’s potential characteristics
Environmental factors and growing techniques can only optimize what’s genetically possible
No amount of cultivation skill can make genetically average seeds produce elite results
Genetic ceiling is real—plants can only express traits contained in their DNA

This explains why experienced growers prioritize genetic selection first, then optimize growing conditions to fully express that genetic potential.

Myth #4: Feminized Seeds Are Genetically Weaker Than Regular Seeds

Some traditional growers maintain that feminized seeds produce weaker plants more prone to hermaphroditism and genetic issues compared to regular (non-feminized) seeds.

The Reality: Modern feminization techniques have evolved significantly. Contemporary research indicates:

Properly produced feminized seeds from reputable breeders show no inherent genetic weaknesses
Modern feminization uses controlled stress techniques or silver thiosulfate rather than harmful chemicals
Hermaphroditic tendencies are primarily genetic traits passed down from parent plants, not a result of feminization itself
Today’s feminized seeds undergo multiple testing generations to ensure stability

Stress-induced hermaphroditism can occur in both feminized and regular seed plants when exposed to environmental stressors like light leaks, temperature extremes, or physical damage.

Myth #5: Cannabis Seeds Expire Quickly

Many cultivators believe cannabis seeds remain viable for only a year or two after production.

The Reality: With proper storage, cannabis seeds can remain viable for much longer periods:

Under optimal conditions (cool, dark, dry, and stable), seeds can remain viable for 5+ years
Germination rates gradually decline over time rather than suddenly dropping to zero
Proper refrigeration in airtight containers with desiccants can extend viability to 10+ years
Different genetic strains have varying natural seed longevity

The key factors affecting seed longevity are temperature stability, humidity control, light exposure, and physical protection from damage.

Myth #6: F1 Hybrids Always Produce Consistent Plants

Many growers believe that F1 hybrid seeds (first-generation crosses between two stable parent lines) always produce identical plants with uniform characteristics.

The Reality: While F1 hybrids do offer greater consistency than later generations, perfect uniformity is a misconception:

Natural genetic variation exists even among F1 siblings
Environmental factors influence phenotypic expression
Different phenotypes can emerge from the same seed batch
True uniformity requires vegetative cloning, not seed propagation

F1 hybrids do typically show more consistency than F2 or later generations, but some variation should still be expected.

Myth #7: Autoflowering Strains Always Produce Lower Quality Cannabis

A persistent myth suggests that autoflowering varieties inherently produce lower quality cannabis with reduced potency compared to photoperiod strains.

The Reality: Modern autoflowering genetics have evolved dramatically:

Early autoflower generations (2008-2012) did produce lower cannabinoid levels
Modern autoflowering strains (post-2015) can produce THC levels comparable to photoperiod varieties
Breeding programs have successfully maintained terpene profiles in autoflowering versions
Yield differences have narrowed significantly through selective breeding

Today’s premium autoflowering genetics represent sophisticated breeding combining Cannabis ruderalis with high-quality photoperiod genetics over multiple generations of selective breeding.

Myth #8: All Seeds from the Same Strain Are Genetically Identical

Many novice growers assume all seeds labeled with the same strain name will produce identical plants.

The Reality: Cannabis strain names represent broad categories rather than genetically identical populations:

Seeds from the same strain batch contain genetic variation
Different seed banks may sell dramatically different genetic versions of identically named strains
Without protected genetic patents, strain names are used inconsistently across the industry
Even stabilized strains exhibit natural variation between individual seeds

This explains why experiences with the “same strain” can vary significantly between growers or seed banks.

Conclusion

The cannabis seed market thrives partly due to persistent myths that confuse beginners and sometimes even experienced growers. By understanding the scientific reality behind these misconceptions, cultivators can make better-informed decisions, set realistic expectations, and achieve more successful outcomes.

As cannabis cultivation continues to professionalize and expand, evidence-based practices will increasingly replace folklore and marketing claims. The future of cannabis cultivation lies not in chasing myths but in understanding the genuine interaction between genetics, environment, and growing practices.

Frequently Asked Questions

How can I tell if cannabis seeds are viable without germinating them?

While no method is 100% accurate without actual germination, viable seeds typically have a hard outer shell, are dark in color (though color varies by strain), and feel firm when gently squeezed. The float test provides limited information but isn’t definitive. The only absolutely reliable viability test is attempting germination under optimal conditions.

Do old cannabis seeds produce weaker plants?

No, older seeds that successfully germinate do not inherently produce weaker plants. While germination rates decline with age, seeds that do germinate typically develop normally. The plant’s strength and quality are determined by genetics and growing conditions, not seed age. However, very old seeds may have slower initial growth during the seedling stage.

Are white or light-colored cannabis seeds always immature?

Not necessarily. While seed color can indicate maturity in some strains, certain cannabis varieties naturally produce lighter-colored seeds even when fully mature. Premature seeds are typically small, fragile, and easily crushed between fingers, regardless of color. Viable light-colored seeds will still have a complete, hard seed coat and proper development.

Why do seeds from the same strain produce different plants?

Cannabis strains are not genetically identical clones but rather populations sharing similar characteristics. Natural genetic variation, different phenotypic expressions, and varying environmental conditions all contribute to differences between plants grown from the same strain’s seeds. True genetic uniformity can only be achieved through cloning, not seed propagation.

Do feminized seeds have a higher chance of becoming hermaphrodites?

Modern, properly produced feminized seeds from reputable breeders do not have inherently higher hermaphroditic tendencies than regular seeds. Hermaphroditism is primarily determined by the genetic stability of the parent plants and environmental stress factors. Low-quality feminized seeds produced using harsh chemical methods may show higher hermaphroditic tendencies, which is why source matters significantly.

Can you tell a strain’s effects from looking at the seeds?

No, it’s impossible to determine a strain’s effects, potency, or chemical profile by examining the seeds. These characteristics are determined by genetics and growing conditions, which cannot be visually assessed from seed appearance. The only way to determine a strain’s effects is to grow it to maturity, properly cure the harvest, and either consume it or have it laboratory tested.

From Landrace to Hybrid: How Cannabis Seed Genetics Have Transformed

by Jason Greenwood | Mar 20, 2025 | Cannabis Culture

Key Takeaways

Landrace cannabis strains are pure, indigenous varieties that evolved naturally in specific geographic regions over thousands of years
Modern hybrid cannabis strains resulted from deliberate breeding programs starting primarily in the 1960s-1970s
The Netherlands played a crucial role in establishing standardized breeding practices and commercializing cannabis genetics
Recent breeding has focused on CBD content, specific terpene profiles, and specialized medical applications
Genetic preservation efforts are increasingly important as original landrace varieties face extinction threats

The evolution of cannabis genetics represents one of the most fascinating chapters in botanical history. From pure landrace varieties that evolved naturally over millennia to today’s sophisticated hybrid strains, the journey of cannabis genetics tells a story of human ingenuity, cultural exchange, and scientific advancement.

The Origins: Landrace Cannabis Strains

landrace strains

Landrace cannabis strains are the original, naturally-occurring varieties that evolved in specific geographic regions without human intervention. These pure genetic lines adapted to their local environments over thousands of years, developing distinct characteristics based on climate, altitude, and other regional factors.

Key landrace regions include:

Hindu Kush Mountains (Afghanistan/Pakistan): Home to indica varieties characterized by compact growth, broad leaves, and sedative effects
Thailand/Laos/Cambodia: Birthplace to energizing sativa varieties with narrow leaves and extended flowering periods
Jamaica: Home to unique varieties adapted to tropical conditions
Mexico: Source of sativa strains that would later influence American cannabis culture
Morocco: Known for hash-producing varieties with resilient characteristics

These landrace strains represent cannabis in its most authentic form—genetically stable populations with consistent traits passed down through natural selection. Before global trade and modern breeding, these distinct genetic pools remained largely isolated from one another.

The First Wave of Hybridization (1960s-1970s)

The modern era of cannabis breeding began when adventurous enthusiasts—often called “strain hunters”—traveled to indigenous growing regions to collect seeds. This period saw the first deliberate crossing of previously isolated genetic lines.

Notable developments during this era:

Haze: Created in Santa Cruz, California by crossing landrace sativas from Colombia, Mexico, Thailand, and India
Skunk #1: Developed by Sacred Seeds through selective breeding of Afghan, Mexican, and Colombian varieties
Northern Lights: Originally bred from Afghan genetics in the Pacific Northwest

These pioneering hybrids combined traits from different landrace varieties, creating new expressions of cannabinoid profiles, terpene production, and growth characteristics. The resulting F1 hybrids demonstrated “hybrid vigor”—enhanced growth rates and yields compared to their parent strains.

The Dutch Revolution (1980s-1990s)

The Netherlands became the epicenter of cannabis breeding innovation thanks to its relatively tolerant laws. Amsterdam’s cannabis coffeeshops created consumer demand for diverse varieties, driving breeders to experiment.

Key developments:

Establishment of seed companies like Sensi Seeds, Dutch Passion, and Greenhouse Seeds
Introduction of standardized breeding practices and documentation
Creation of iconic strains like White Widow, Super Silver Haze, and Jack Herer
First Cannabis Cup competitions establishing quality standards and driving innovation

Dutch breeders pioneered techniques for stabilizing desirable traits through backcrossing and inbreeding, creating true-breeding lines that would produce consistent offspring. This marked the transition from chance hybridization to methodical breeding programs.

The CBD Renaissance and Medical Breeding (2000s-Present)

The discovery of CBD’s therapeutic potential revolutionized breeding objectives. While early hybrid development focused primarily on THC potency and recreational effects, modern breeding encompasses a broader range of goals.

Recent genetic developments include:

High-CBD strains like Charlotte’s Web, developed specifically for medical applications
Balanced THC varieties offering more nuanced effects
Terpene-focused breeding for specific aromatic profiles and entourage effects
Autoflowering strains incorporating ruderalis genetics for easier cultivation
Feminized seed technology eliminating male plants in crops

Today’s breeding programs often utilize genetic testing to identify specific cannabinoid and terpene profiles, allowing for increasingly precise trait selection. Some advanced breeders employ marker-assisted selection to identify desirable genetic traits without waiting for plants to mature.

The Science Behind Modern Cannabis Breeding

Modern cannabis breeding combines traditional agricultural techniques with cutting-edge science:

Phenotype Hunting: Breeders grow multiple seeds from the same cross to identify individuals with optimal expressions of desired traits.

Backcrossing: A selected hybrid is crossed back to one of its parent strains to strengthen specific desired characteristics while maintaining genetic stability.

Polyploidy: Some breeders experiment with chemical treatments to create plants with extra sets of chromosomes, potentially increasing potency and vigor.

Genetic Mapping: Research institutions are sequencing cannabis genomes to better understand the genetic basis for various traits.

The Future of Cannabis Genetics

As legal barriers continue to fall, cannabis breeding is entering an unprecedented era of innovation. Future developments may include:

CRISPR gene editing to create varieties with specific cannabinoid profiles
Resurrection of lost landrace genetics through seed preservation efforts
Development of varieties optimized for different extraction methods
Tailored medicinal strains targeting specific health conditions
Industrial hemp varieties with enhanced fiber or seed production capabilities

Preserving Genetic Heritage

As hybridization accelerates, there’s growing concern about landrace preservation. Original landrace varieties represent irreplaceable genetic resources that could hold traits valuable for future breeding programs, especially adaptability to climate change.

Several organizations now focus on collecting and preserving landrace genetics before they disappear due to habitat loss, conflict in native regions, or cross-pollination with introduced varieties.

Conclusion

The journey from landrace to hybrid represents a fascinating intersection of natural evolution and human intervention. Today’s cannabis diversity stems from thousands of years of natural adaptation followed by decades of intentional breeding. As cannabis continues its transition from prohibition to legitimacy, we can expect genetic development to accelerate even further, creating varieties tailored to increasingly specific consumer and industrial needs.

The true power of cannabis genetics lies in this remarkable adaptability—a plant that has evolved alongside humanity for millennia continues to transform to meet our changing needs, representing one of botany’s most dynamic success stories.

Glossary of Cannabis Breeding Terminology

Backcrossing: The process of crossing a hybrid with one of its parent strains to reinforce specific genetic traits.

Chemotype: The chemical profile of a cannabis plant, including its cannabinoid and terpene composition.

Cultivar: A cultivated variety of cannabis with distinct traits that can be maintained through proper breeding.

F1 Hybrid: First-generation cross between two different pure breeding lines.

Feminized Seeds: Seeds genetically engineered to produce only female plants.

Genotype: The genetic makeup of a cannabis plant.

Heterozygous: Containing different alleles of a particular gene or genes.

Homozygous: Containing identical alleles of a particular gene or genes, leading to consistent trait expression.

IBL (Inbred Line): A strain that has been inbred to the point of producing consistent offspring.

Landrace: Naturally occurring, indigenous cannabis variety that has adapted to its local environment.

Phenotype: The observable characteristics of a cannabis plant resulting from the interaction of its genotype with the environment.

Phenohunting: The process of growing multiple plants from the same seed stock to identify individuals with superior traits.

Ruderalis: A cannabis subspecies native to Russia with autoflowering properties.

Stabilizing: The process of breeding for consistency in traits through multiple generations.

Frequently Asked Questions

What is the difference between indica and sativa genetics?

Indica and sativa represent the two main subspecies of cannabis. Indica genetics typically originated in mountainous regions like the Hindu Kush, producing plants with broader leaves, shorter stature, and sedative effects. Sativa genetics, originating in equatorial regions, typically produce taller plants with narrower leaves and more energizing effects. Modern hybrids often combine both genetic lineages.

Are landrace strains more potent than modern hybrids?

Generally, no. Modern hybrids have been selectively bred for higher cannabinoid content, particularly THC. Landrace strains typically have more moderate potency but may offer unique terpene profiles and effect balances not found in modern varieties.

Why is preserving landrace genetics important?

Landrace varieties represent irreplaceable genetic diversity developed over thousands of years of natural selection. These genetics may contain valuable traits for disease resistance, climate adaptation, or unique cannabinoid/terpene profiles that could be vital for future breeding programs.

What are autoflowering cannabis genetics?

Autoflowering genetics incorporate DNA from Cannabis ruderalis, a subspecies that flowers based on plant age rather than light cycle changes. This trait allows plants to flower automatically regardless of light schedule, making cultivation easier especially in regions with short growing seasons.

How are feminized seeds created?

Feminized seeds are produced by inducing female plants to produce pollen through chemical treatment or stress techniques. When this female-derived pollen is used to pollinate another female plant, the resulting seeds have two X chromosomes, guaranteeing female offspring nearly 100% of the time.

How has cannabis genomic research advanced breeding?

Genomic research has identified specific genes responsible for cannabinoid production, terpene synthesis, and growth characteristics. This allows breeders to test plants at early growth stages to identify desirable traits without waiting for full maturation, significantly accelerating the breeding process.
