Plant Selection Criteria

Plant selection criteria encompass the observable and measurable traits that breeders and cultivators evaluate when choosing parent genetics or identifying phenotypes for preservation and further breeding. These criteria include morphological features (plant height, branching structure, leaf shape), developmental patterns (flowering time, growth rate), and biochemical markers (terpene profiles, cannabinoid ratios). Systematic evaluation of these traits across generations helps establish stability and consistency in a breeding line. Selection criteria form the foundation of intentional cannabis breeding programs, where breeders document and prioritize specific characteristics to develop stable cultivars. Understanding these criteria is essential for anyone working in seed production, clone preservation, or genetic documentation.

Breeders establish clear selection criteria early in their programs to maintain genetic direction and ensure that desirable traits concentrate across generations. Detailed phenotype tracking and consistent evaluation against predefined criteria allows breeders to identify keeper plants, eliminate off-type individuals, and build reliable seed stock or clone libraries.
