Phenotype Culling
Phenotype culling is a selective breeding practice where breeders identify and remove plants that don't meet desired visual, structural, or aromatic criteria during the growing cycle. This process occurs before flowering or early in flower, allowing breeders to concentrate resources on plants expressing target traits. Culling decisions typically focus on plant vigor, branching pattern, leaf structure, resin production, and preliminary aroma profiles. The practice is fundamental to stabilizing desirable genetics and improving consistency within a strain family across multiple generations. By removing off-type or recessive phenotype expressions, breeders narrow genetic diversity toward a commercial or breeding standard.

Phenotype culling directly impacts breeding efficiency by reducing grow-out space waste and establishing clearer phenotypic windows for selection. Combined with genotype testing, culling creates the foundation for developing F1 hybrids, stable IBLs, and commercially uniform cultivars.
