Bast Fiber Lineages

Bast fiber lineages refer to cannabis cultivars historically selected or bred for fiber production rather than cannabinoid content. These plants typically exhibit tall growth, thicker stalks, and longer internodal spacing—traits valued in industrial hemp breeding programs. Bast fibers (phloem tissue) from the stem outer layers have been processed for textiles, rope, and composite materials in certain jurisdictions where such cultivation is legally permitted. Lineage records frequently report European and Asian hemp breeding programs as primary sources for documented fiber-focused genetics. Contemporary breeding in this category often emphasizes stalk yield, fiber length, and structural integrity alongside legal cannabinoid compliance.

Breeders working with bast fiber lineages prioritize morphological and agronomic traits over cannabinoid profiles, making crosses within this family useful for developing dual-purpose cultivars or restoring structural vigor in indoor-adapted lines. Understanding these genetics supports both historical documentation and modern hemp breeding infrastructure in jurisdictions permitting fiber productio
