Fiber Quality Traits

Fiber quality traits encompass the physical characteristics of cannabis plant stem material, including bast fiber length, strength, and processing suitability. These traits have historical significance in industrial hemp breeding programs, where selection focused on maximizing usable fiber yield and tensile properties. Assessment involves measuring stem diameter, fiber bundle cohesion, and degradation resistance—factors that influence potential applications in textiles, composites, and paper production. Modern genetics research continues to document heritability patterns in fiber morphology across different cultivar backgrounds. Understanding fiber quality requires distinction from cannabinoid or terpene-focused breeding, as fiber traits operate under separate phenotypic and genetic parameters. Documentation of these traits remains relevant for breeders developing dual-purpose or special

Breeders selecting for fiber quality typically employ field assessments of stem strength and retting characteristics. Fiber trait selection has historically been decoupled from THC/CBD breeding but represents an active area in industrial and heritage cultivar development programs.
