Fiber Type Plants

Fiber-type cannabis plants refer to varieties bred and cultivated primarily for stem fiber production rather than cannabinoid content. These plants, often called hemp when grown under legal fiber-production frameworks, typically exhibit tall, woody stem structures with minimal branching and reduced flower density compared to resin-focused cultivars. Fiber genetics emphasize cellulose and lignin development in the stem—traits that breeders have selected for across centuries of agricultural use. The terpene profile in fiber-type plants is generally less complex and aromatic than cannabis bred for resin accumulation, reflecting the different selection pressures on volatile compounds. Understanding fiber-type morphology and chemistry is essential for breeders working in industrial hemp, textile genetics, and dual-purpose cultivar development.

Breeders working with fiber-type genetics prioritize stem strength, height, and uniformity—traits that correlate with lower terpene expression and reduced secondary metabolite investment. Crossing fiber lines with resin-focused parents remains a specialized breeding goal for developing dual-purpose cultivars that balance biomass yield with cannabinoid or terpene production.
