Abstract

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.
