Sour Phenotype

The Sour phenotype family encompasses cannabis plants characterized by terpene profiles commonly associated with acidic, tangy, or fermented aromatic notes. Lineage records frequently report this phenotypic expression emerging from crosses involving Sour Diesel, Sour Bubble, and related cultivars that carry elevated levels of acidic terpenes like limonene and caryophyllene. Breeders working in this category often observe heightened volatile organic compound production and distinctive flavor precursors during flowering. The Sour phenotype represents a recognizable expression rather than a single genetic lineage, appearing across multiple breeding programs and seed lines. Selection for sour characteristics typically involves sensory evaluation during breeding trials and continued backcrossing to stabilize these aromatic traits.

Breeders actively select for Sour phenotypes to develop cultivars with distinctive aromatic profiles for commercial and research purposes. Stability of sour expression varies across genetic backgrounds, making phenotypic selection and clone evaluation critical tools in breeding programs targeting this family.
