Fiber Type Cannabis

Fiber-type cannabis, commonly referred to as hemp in legal contexts, represents plants selectively bred for stem and stalk production rather than cannabinoid accumulation. Historical cultivation prioritized tall growth, robust fiber bundles, and minimal flowering investment—traits distinct from drug-type lineages. Fiber varieties typically exhibit lower cannabinoid concentrations and were developed across temperate regions for textile, paper, and composite applications. Breeding records show fiber-oriented selection produced characteristic plant architectures: tall, slender stems with reduced branching and leaf-to-stalk ratios favoring processing efficiency. Modern fiber genetics often carry haplotypes associated with rapid stem elongation and cellulose density, making them agronomically distinct from resin-focused cultivars.

Breeders maintaining fiber genetics prioritize stalk yield, fiber uniformity, and processing traits over secondary metabolite production. Cross-breeding fiber and cannabinoid-focused lines requires careful phenotype tracking to maintain separation for regulatory and commercial purity.
