2025 Trends in Genetics & Breeding

The foundation of every successful cannabis harvest starts with genetics. Whether you’re a seasoned grower or just starting your journey, the genetic profile of your plants will play a vital role in their health and overall performance. Beyond influencing traits such as pest resistance, unique flavors, and yield, having highly sought-after genetics as a commercial cannabis brand can set you apart in an increasingly competitive industry.

With consumers often gravitating toward distinctive strains and terpene profiles, superior genetics can become a cornerstone of customer loyalty. So, staying informed on current and emerging trends in cannabis breeding and genetics is more important than ever. In this blog, we’ll explore the latest trends shaping cannabis genetics and offer insights to help you grow and thrive in 2025!

Exploring Popular Cannabis Strains in 2025

As we enter 2025, the cannabis market continues to be dominated by terpene-rich and high-THC or CBD varieties. Modern consumers are drawn to strains that align with their desired effects, such as relaxation, creativity, or energy — while also appreciating trending flavor profiles like fruity Zkittlez or sweet Lemon Cherry Gelato. In fact, Zkittlez as a parent profile has been consistently winning global awards across many sub-strains for years now.

Regional differences also remain a fascinating aspect of breeding and genetics. California is still the major trendsetter for most popular genetics, and Colorado has evolved into a very vibrant breeding scene as well. Strains tend to migrate in popularity from the West Coast eastward, but New York is anticipated to become the East Coast epicenter of breeding and genetics in the coming years. The West Coast tends to be into gas and sour flavor profiles while the East Coast is known for chem varietals, and candy gas is a terpene profile currently popular across both coasts.

Overall Trends Among Cannabis Geneticists and Breeders

In recent years, cannabis geneticists and breeders have been pushing the boundaries of innovation, with several key trends emerging across the industry.

Breeding for Specific Traits

One significant trend is the deliberate breeding of strains for specific traits, such as pest resistance in particular climates, higher yields in commercial settings, distinct flavor profiles to meet consumer demands, suitability for hash washing, ease of cultivation, and more. This allows growers to meet market demands while optimizing production efficiency.

Focus on Terpene Profiles

There’s also been a growing focus on terpene profiles in the breeding process, leading geneticists to look for strains that express certain terpenes. This is due to a shifting focus amongst connoisseur consumers toward terpene profiles over THC potency or basic indica/sativa/hybrid labels.

However, the majority of everyday flower purchasers still chase potency numbers and want easier-to-understand buckets for effects. So, while terpene profiles tend to be particularly important for craft or high-end brands, potency is still king, and indica/sativa/hybrid labels are still common.

The Intersection of Sustainability & Genetics

While sustainability often takes a backseat to other business decisions, the intersection of genetics and sustainability is also worth mentioning. Breeders are developing water-efficient and fast-growing strains to reduce environmental impact, emphasizing regenerative cultivation practices, and creating resilient strains capable of thriving in diverse climates. With breeders tailoring strains to both local climates and consumer preferences, they can ensure that genetics are optimized for both cultivation and consumption.

The Growing Popularity of Small-Batch and Craft Cannabis

Small-batch and craft cannabis have been gaining significant traction in recent years, as more consumers are seeking premium, personalized experiences from the brands they support.

Small-batch cannabis refers to cultivation on a smaller scale, often by independent growers or boutique farms, which allows for more attention to detail and quality control. Craft cannabis takes this a step further by focusing on producing highly specialized, artisanal strains with unique genetic profiles. The growing demand for these types of cannabis is largely due to their appeal to connoisseurs who value the diversity of flavors, aromas, and effects that mass-produced strains often lack. By offering rare strains or special phenotypes that are not widely available, growers can carve out a competitive edge in the marketplace and keep their customers coming back time and time again.

Craft cannabis is often seen as the “farm-to-table” equivalent of cannabis—similar to how organic foods command a premium price for their sustainability and high-quality ingredients, so too does craft cannabis. While the price point for craft cannabis can be higher than its mass-produced counterparts, the increased costs reflect those superior genetics, cultivation practices, and end products.

The Rise of In-House Pheno Hunting

Pheno hunting is the process of selecting the most desirable plants, or phenotypes, from a group of genetically similar seeds based on specific traits. Each cannabis seed carries genetic potential from its parent plants, and the way these genes are expressed can vary — leading to differences in traits such as growth patterns, flavor profiles, potency, yield, aroma, and resistance to pests or diseases. Cultivators will germinate multiple seeds of the same strain, sometimes in the hundreds to thousands, to observe the plants as they grow, and then evaluate them to identify the standout phenotypes that best meet their goals or align with their customer preferences. Once a desirable phenotype is identified, it can be cloned or bred to further enhance its unique characteristics.

More and more cultivators opt for in-house pheno hunting because it provides a significant competitive advantage in an increasingly crowded market. If consumers can get the same strain from 15 different brands, that’s a lot of options — but if you’re the only brand with a certain strain, everyone who wants that strain has to come to you. When cultivators have proprietary strains, it enables them to differentiate their products, build customer loyalty, and establish a strong presence in the market. Oftentimes, even if a particular strain is relatively popular, quality-focused growers will seek to cultivate a prized cut or clone of it which then tends to carry even more weight than its generic counterpart.

Conventional Cloning vs. Tissue Culture

Tissue cloning, or tissue culture propagation, is a cutting-edge method used to reproduce cannabis plants. This technology is anticipated to be the future for sophisticated cannabis operators once they find phenos they want to keep. It’s a technique that involves taking a small sample of plant tissue, such as a leaf or stem, and cultivating it in a sterile, nutrient-rich environment. The tissue is encouraged to grow into a genetically identical clone of the original plant.

This process, often done in a laboratory setting, helps cultivators ensure genetic stability much more than traditional cloning methods such as taking cuttings from a mother plant. It can also be used to clean up genetics that may have become contaminated and rejuvenate them back to their original state. However, it does take technical knowledge to execute.

You may be familiar with Driscol’s, the fruit agriculture company you likely got your berries from this morning at breakfast. Driscol’s actually uses tissue culture exclusively to ensure plant consistency! With applications in mainstream agriculture, the cannabis industry is only beginning to unlock the power of tissue culture.
