Bast Fiber Content

Bast fiber content refers to the structural cellulose and lignin composition in cannabis stem tissue, which determines fiber quality and yield potential. Cannabis plants with elevated bast fiber profiles have been traditionally selected in breeding programs focused on dual-purpose or fiber-dominant cultivars. Bast fibers—the long, strong cells in the phloem—are valued in fiber-focused agriculture for textile, construction, and composite material applications. Lineage records frequently report bast fiber traits concentrated in hemp-derived genetics and certain landrace families developed under fiber-agricultural selection pressure. Understanding bast fiber content is central to agricultural genetics work, as it influences plant structure, stem strength, and harvesting considerations across different cultivation models.

Breeders working in fiber-agriculture and dual-purpose breeding programs actively select for bast fiber content to optimize stem quality, mechanical properties, and processing efficiency. Genetics with robust bast development are often crossed to introduce fiber traits into specialty cultivars while maintaining desired cannabinoid or terpene profiles.
