Studies have been conducted to evaluate the genetic potential of cotton species and to develop disease and pest resistant cotton varieties from them. The significance of the level of leaf hairiness in the representatives of the Gossypium L. family in tolerance to sucking pests, spider mite, aphid, was studied. Resources were obtained to measure or qualitatively assess leaf hairiness, transfer the hairiness marker for pest tolerance into the genome of G. hirsutum L., and create cultivars with a combination of tolerance and economic traits. In the C2 plants of the combinations obtained by cross-breeding the wild-type ridges with twisting hairiness with the analyzer L-001 line, separation of the hairiness character was noted, its ratio was 3:1 according to the phenotype (1:2:1 according to the genotype). This separation in second-generation hybrids indicates that the feather shape trait is monogenic in nature.
