Allele Fixing
Allele fixing refers to the breeding practice of stabilizing homozygous expression of specific traits across generations—typically by repeated selection and selfing or backcrossing. In cannabis breeding, fixation targets observable characteristics: cannabinoid ratios, terpene profiles, plant architecture, flowering time, or disease resistance. Breeders working in this category aim to create stable line genetics where target alleles breed true, reducing phenotypic variance. This foundational technique underpins most modern seed releases and is essential for reproducible cultivar development. Allele fixing requires multiple generations of controlled crosses and phenotypic assessment to confirm stability across offspring populations.

Allele fixing enables breeders to isolate and lock in desired traits, moving from F1 hybrids to stable F2, F3, or inbred lines suitable for commercial seed production. Without fixation work, trait expression remains unpredictable; with it, cultivars can reliably express their marketed characteristics across multiple generations.
