Cytogenetics
Cytogenetics in cannabis breeding refers to the study of plant chromosomes and their behavior during cell division, reproduction, and inheritance. Breeders use cytogenetic analysis to understand ploidy levels (haploid, diploid, triploid, polyploid), detect chromosomal abnormalities, and track genetic material through crosses. Karyotyping and chromosome counting have helped document that most stable cannabis cultivars are diploid (2n=20), while some breeding lines exhibit polyploidy or aneuploidy. This field underpins understanding of fertility, hybrid vigor, trait segregation, and why certain crosses produce sterile or unstable offspring. Cytogenetic data is increasingly used alongside molecular markers to validate parentage and improve breeding precision.

Breeders apply cytogenetic knowledge to diagnose sterility, guide polyploid breeding programs, select for chromosome stability in new lines, and understand why specific crosses succeed or fail. Cytogenetic screening helps prevent wasted generations on genetically unstable material.
