Abstract: The existence of a robust gene pool, encompassing varieties or accessions resistant to both abiotic and biotic environmental factors, stands as a crucial determinant for the development of cotton cultivation. At the Genetic Resources Institute of the Ministry of Science and Education of Azerbaijan, the cotton collection encompasses approximately 1500 accessions. The main objective of the study was to conduct a comprehensive assessment of drought resistance and wilt sensitivity within the cotton collection and to compare nucleic acid synthesis in genotypes exhibiting diverse degrees of drought resistance.As a result of the assessment of drought resistance the cotton accession were divided into groups with varying degrees of resistance. Genotypes characterized by resistance to both abiotic and biotic environmental factors have been identified. А correlation has been observed between the drought sensitivity and the activity of nucleic acid synthesis. In drought-resistant accessions, stress triggers the activation of DNA and RNA synthesis, indicating an increase in the physiological labilityand enhancement of functional activity of the genetic apparatus. Conversely, in stress-sensitive genotypes a reduction in nucleic acid synthesis was observed. The degree of stress resistance represents the inherited potential ability of the organism to adapt and is realized under the influence of an extreme factor.
