Cannabis breeding is a process that involves the careful selection and crossing of parent plants to create offspring with desirable traits. One of the most critical factors in cannabis breeding is understanding phenotypes. In this article, we’ll explore what cannabis phenotypes are, how they impact breeding, and the various types of phenotypes.
What are Cannabis Phenotypes?



Phenotypes refer to the observable traits of a plant or organism, which are a product of the interaction between the genetic makeup and environmental factors. In cannabis breeding, phenotypes are essential as they determine the physical and chemical characteristics of the plant.
There are various phenotypes present in cannabis, and breeders select the most desirable ones to create new strains. These desirable traits could include aroma, flavor, potency, growth rate, yield, and disease resistance.
What is genotype vs phenotype cannabis?



Genotype and phenotype are two terms that are often used in the context of cannabis breeding and cultivation. Here’s a brief explanation of each:
Genotype refers to the genetic makeup of a plant, including its DNA and inherited traits. In cannabis breeding, genotype refers to the specific combination of genetic traits that a plant inherits from its parent plants. Breeders can selectively breed plants with desired genotypes to create new strains with specific characteristics.
Phenotype, on the other hand, refers to the physical traits and characteristics of a plant that result from its genotype and its interaction with the environment. These can include things like the plant’s height, leaf shape, flowering time, cannabinoid and terpene profile, and more. In cannabis breeding, phenotype is important because it determines how a plant will look, smell, and taste, as well as the effects it will produce when consumed.
To summarize, genotype refers to the genetic traits that a plant inherits, while phenotype refers to the physical traits and characteristics that result from those genetics and the environment. Both genotype and phenotype are important factors in cannabis breeding and cultivation, as they determine the traits and characteristics of the final product.
The Role of Phenotypes in Cannabis Breeding



Phenotypes play a crucial role in cannabis breeding, as they determine the success of the breeding process. Breeders must select the most desirable phenotypes to ensure that the cannabis seed offspring has the desired characteristics.
To achieve this, breeders need to understand the different types of phenotypes and how they influence breeding. Let’s explore some of the common phenotypes present in cannabis.
Types of Cannabis Phenotypes
1. Growth Phenotypes
Growth phenotypes refer to the physical appearance and characteristics of the plant, such as height, leaf shape, and color. These phenotypes are essential as they can affect the plant’s yield and growth rate.
2. Aroma and Flavor Phenotypes
Aroma and flavor phenotypes refer to the scent and taste of the plant, which are essential considerations for consumers. Some of the aroma and flavor profiles include fruity, earthy, citrusy, and spicy.
3. Potency Phenotypes
Potency phenotypes refer to the concentration of cannabinoids, such as THC and CBD, in the plant. These phenotypes are essential as they determine the plant’s psychoactive effects.
4. Disease Resistance Phenotypes
Disease resistance phenotypes refer to the plant’s ability to resist pests and diseases. These phenotypes are essential as they ensure the plant’s health and productivity.
Cannabis Phenotype List



- Indica – Indica plants are known for their relaxing and sedative effects. They are typically shorter and bushier than Sativa plants, with wider leaves and a shorter flowering time.
- Sativa – Sativa plants are known for their energizing and uplifting effects. They are typically taller and more slender than Indica plants, with narrower leaves and a longer flowering time.
- Hybrid – Hybrid plants are a cross between Indica and Sativa plants, combining the effects of both. They can have a wide range of characteristics depending on the specific genetics of the plant.
- Ruderalis – Ruderalis plants are a lesser-known variety of cannabis, originating from Central Asia. They are typically smaller than Indica or Sativa plants, with a shorter flowering time. Ruderalis plants are often used in breeding to create auto-flowering strains.
- Landrace – Landrace strains are cannabis strains that are indigenous to a particular geographic region. They are often highly adapted to the local environment and have unique characteristics and effects.
- High-CBD – High-CBD strains are cannabis strains that are bred to have a higher concentration of the cannabinoid CBD (cannabidiol) and lower levels of THC (tetrahydrocannabinol). They are often used for medicinal purposes.
- High-THC – High-THC strains are cannabis strains that are bred to have a higher concentration of THC, which is the psychoactive compound in cannabis that produces the “high” associated with the plant.
These are just a few of the many cannabis phenotypes that exist. Breeders and growers can create and cultivate strains with unique combinations of traits to suit a wide range of consumer preferences and needs.
Phenotype Selection in Cannabis Breeding



Phenotype selection is a critical process in cannabis breeding. Breeders must select the most desirable phenotypes to ensure that the offspring has the desired traits. This process involves careful observation and analysis of the plants to determine which phenotypes are most desirable.
Breeders also use genetic testing to determine the presence of desirable traits in the parent plants. This testing allows them to identify which plants have the desired phenotypes and use them in the breeding process.
How many phenotypes of cannabis plant are there?
The number of cannabis plant phenotypes is difficult to determine as new strains are constantly being developed through breeding and genetic manipulation. However, it is estimated that there are thousands of cannabis phenotypes that exist today, each with its own unique combination of characteristics and effects.
These phenotypes can be classified into categories such as Indica, Sativa, Hybrid, Landrace, Ruderalis, High-CBD, and High-THC strains, but there are also many variations within each category. Overall, the diversity of cannabis phenotypes is one of the many factors that contribute to the plant’s popularity and versatility in various industries.
Final Thoughts
In conclusion, cannabis breeding is a complex process that involves the selection and crossing of parent plants to create offspring with desirable traits. Phenotypes play a crucial role in this process as they determine the physical and chemical characteristics of the plant.
Understanding the various types of phenotypes present in cannabis is essential for breeders. Growth, aroma and flavor, potency, and disease resistance are some of the most common phenotypes.
In cannabis breeding, phenotype selection is a critical process that ensures the success of the breeding process. By carefully selecting the most desirable phenotypes, breeders can create new strains with the desired traits.
