This article presents data on the inheritance and variability of leaf shape in intra- and interspecific hybrids F1 and F2 obtained from varieties of tetraploid cotton species (G.hirsitum L., G.tricuspidatum Lam.). The obtained results showed that intermediate inheritance is observed in the trait of the leaf shape in F1 hybrids. In F2, splitting was observed in a ratio of 1:2:1. The study of the inheritance of the trait in intra- and interspecific hybrids F1, F2 revealed semi-dominant, polygenic inheritance.
