This article presents the results of a study on the inheritance of earliness in parental forms and F1 hybrids of Gossypium hirsutum L. (G.hirsutum L.) The inheritance, variability, and formation of earliness in F1 hybrids obtained through hybridization were assessed using mathematical and statistical analysis. The growth period of F1 hybrid plants ranged from 115 to 118 days. Compared to parental forms, 50% of the bolls opened 2-3 days earlier. The highest earliness was observed in the hybrid combinations F1S-6580xGuliston and F1S-8290xCarisma (M=115 days). In contrast, the F1S-6575xADNS-1 (118 days) hybrid combination exhibited later maturity than other hybrids, which was attributed to incomplete dominance.
