Indica Dominance

Indica dominance refers to cannabis plants exhibiting phenotypic traits commonly associated with Cannabis indica subspecies, including shorter stature, broader leaflets, and faster flowering cycles. This classification describes plant morphology and developmental patterns rather than a specific terpene profile, though indica-dominant cultivars often feature terpene combinations like myrcene-forward aromatics. Breeders working in this category typically select for compact plant architecture, earlier maturation, and broader-leaf genetics derived from Central Asian and Hindu Kush lineages. The term "dominance" reflects the genetic expression ratio when indica genetics are crossed with sativa or hybrid parents. Understanding indica-dominant plant structure helps breeders optimize for indoor cultivation, yield timing, and regional adaptation.

Breeders selectively maintain indica-dominant genetics to produce shorter, bushier plants suited to space-limited environments and shorter growing seasons. Indica dominance is often crossed with sativa genetics to balance flowering time, plant height, and cannabinoid/terpene profiles in commercial breeding programs.
