Institute of Genetic Resources of the Ministry of Science and Education of Azerbaijan, AZ 1106, Baku, Azerbaijan, Abstract For this study, 77 best varieties of cotton were selected from the collection of the National Gene Bank of Azerbaijan. Due to the fact that the previously studied characteristics of these samples turned out to be incomplete, it was advisable to supplement information on such features and properties as fiber yield, the main qualitative features tested on the HVI (High Volume Instrument) electronic system in accordance with a unified international classification, as well as resistance of plants to wilt. In the process of studying additional traits, a significant divergence of traits was revealed, which made it possible to distinguish from the total number of 15 genotypes characterized by a successful combination of the studied traits. Along with this, it was found that the susceptibility of the main part of the genotypes is zero. In the article under discussion, the definition of correlations between various paired features is considered. In the selected genotypes, a positive or negative orientation of the relationship was established, as well as the degree of relationship, which, depending on the paired traits, varied from a low unreliable to a highly significant value. The results of this study can serve as a basis for enriching the genetic diversity of the collection and subsequent use in various directions.
