Fiber Resin Polymorphism
Fiber Resin Polymorphism describes genetic variation in how cannabis plants allocate resources between structural cellulose/lignin development and secondary metabolite (cannabinoid/terpene) production. Plants exhibiting this trait show wide phenotypic range—from fiber-dominant cultivars with minimal resin heads to resin-heavy phenotypes with reduced structural tissue. This polymorphism is controlled by multiple loci and environmental factors, making it a key consideration in breeding programs targeting either fiber (hemp) or flower production. Lineage records frequently report this variation appearing across diverse genetic backgrounds, particularly in populations derived from Central Asian and Eastern European landraces.

Breeders leverage fiber-resin polymorphism to diverge hemp and cannabis flower lines, selecting for cellulose-rich plants in fiber breeding or resin-dense plants in medical/recreational programs. Understanding this trait's heritability helps predict offspring phenotypes and stabilize breeding goals across generations.
