Many useful genes of wild relatives of cotton are almost lost in the process of long-term selection and increasing cultivation of breeding varieties. All this dictates the need to look for new genotypes with useful traits.
For conducting breeding genetic studies and obtaining interspecific hybrids, it is advisable to use the wild polyploid species G.tomentosum with the species G.hirsutum L., since they freely intersect and give full-fledged hybrid seeds.
