Photoperiod Selection
Photoperiod selection refers to a plant's flowering response to light cycle duration, a fundamental breeding consideration in cannabis genetics. Most commercial cultivars fall into two categories: photoperiod-dependent (flowering triggered by shortened daylight) and autoflowering (flowering by age regardless of light). Breeders carefully select and stabilize photoperiod traits to control harvest timing, plant maturity, and crop predictability. Understanding photoperiod genetics is essential for breeding programs targeting specific growing environments—from controlled indoor cultivation to outdoor seasonal production. This trait influences breeding decisions around lifecycle stability, yield consistency, and adaptation to regional growing windows.

Breeders select for photoperiod stability to ensure reliable flowering windows and reduce phenotypic variation within a line. Photoperiod genetics are foundational when developing cultivars for specific cultivation methods, indoor schedules, or outdoor harvest calendars.
