Fiber Yield

Fiber yield is not a terpene but rather an agronomic trait describing the production volume of usable plant fiber from cannabis biomass. This characteristic has historical significance in hemp breeding programs, where fiber quality and quantity directly impact industrial applications like textiles, composites, and paper production. Breeders working in fiber-focused genetics prioritize plant morphology, stem structure, and overall biomass accumulation rather than cannabinoid or terpene profiles. Modern fiber-yield selection involves assessing stalk diameter, cellulose content, and retting properties—how quickly fiber separates from woody core material. This trait remains central to agricultural cannabis breeding in regions where industrial hemp cultivation is legally established.

Cannabis breeders targeting fiber production select for tall plants with thick, sturdy stems and minimal branching to maximize harvestable fiber per plant. Fiber-yield programs often deprioritize resin production, resulting in low-THC, low-CBD cultivars optimized for structural material value rather than cannabinoid content.
