Clone Integrity

Clone Integrity refers to the genetic stability and trueness-to-type of asexually propagated cannabis plants across generations. When a clone maintains consistent phenotypic expression—morphology, terpene profile, growth rate, and cannabinoid ratios—across multiple propagation cycles, it demonstrates high clone integrity. This trait is essential for commercial cultivation and breeding programs that require predictable, replicable harvests. Breeders and cultivators track clone integrity through regular phenotypic observation and occasional genetic testing to detect genetic drift, somaclonal variation, or contamination that may accumulate over many rounds of asexual reproduction.

Breeders use clone integrity assessments to establish stable mother plants and validate that elite phenotypes remain consistent across propagation. Poor clone integrity signals the need to refresh genetics or investigate environmental stress, pathogen pressure, or epigenetic drift that may compromise breeding stock.
