Seed Set

Seed set is not a terpene, but rather a reproductive trait describing the plant's capacity to produce viable seeds when pollinated. In cannabis breeding contexts, seed set efficiency—the percentage of flowers that develop into mature seeds—is a critical quantitative measure of plant fertility and breeding success. Breeders assess seed set by evaluating pollination success rates, embryo viability, and seed maturation timing across generations. Strong seed set is particularly valued in preservation work and commercial seed production, where consistent germination rates and genetic stability depend on reliable seed development. Environmental factors including light, temperature, humidity, and pollination method all influence seed set outcomes.

Breeders prioritize seed set as a foundational metric when developing stable cultivars, establishing seed banks, or creating F1 hybrids. High seed set rates enable efficient selection pressure and reduce generational time in stabilization programs, while poor seed set may indicate genetic incompatibility, environmental stress, or fertility issues requiring investigation.
