Phenotype Curation

Phenotype curation refers to the systematic selection and stabilization of observable plant characteristics across generations of cultivation. Breeders employing phenotype curation evaluate traits such as plant structure, flowering time, terpene profiles, and cannabinoid ratios to identify and propagate desirable expressions within a genetic line. This practice differs from creating entirely new crosses; instead, it refines existing genetics by repeatedly selecting specimens that meet specific criteria. Phenotype curation is foundational to seed-line development and the maintenance of stable, predictable cultivars. Well-curated phenotypes form the basis of many named strains available in the commercial market today.

Phenotype curation allows breeders to maximize consistency within a limited genetic background without introducing new parentage. By selecting for stable, repeatable traits across multiple generations, breeders reduce phenotypic variance and establish reliable breeding stock for further hybridization or seed production.
