A breeder’s field guide for exploring the forgotten edges of cannabis genetics. The Reverse Selector’s Cookbook documents unusual phenotype hunting methods inside major gene pools, focusing on reverse selection, recessive trait exploration, narrowleaf and broadleaf divergence, hidden terpene pathways, and rare expressions buried inside heritage populations. Designed for serious breeders, collectors, and preservationists, this book presents experimental projects, selection frameworks, and real-world breeding concepts aimed at uncovering genuinely new discoveries from existing genetics.
