Seed Cultivars

Seed cultivars represent cannabis genetics maintained and propagated through sexual reproduction, where breeders intentionally cross parent plants to produce seeds with specific trait combinations. Unlike clones, seed cultivars introduce genetic recombination in each generation, allowing breeders to stabilize desired characteristics across multiple phenotypes or create new variation. Seed cultivars are foundational to modern cannabis breeding programs, enabling preservation of genetic diversity and adaptation to different growing environments. This category includes both regular seeds (producing male and female plants) and feminized seeds (bred to produce predominantly female plants). Seed cultivar stability often depends on selection pressure over multiple generations—early-generation seeds may show wider phenotypic ranges than later stabilized lines.

Breeders working with seed cultivars focus on phenotypic selection, inbreeding coefficients, and trait heritability to develop stable IBL (inbred line) or F1 hybrid genetics. Seed propagation allows documentation of genetic pedigrees across generations, supporting comparative breeding research and trait mapping within established cultivar families.
