Inheritance and Variability of Some Agronomic Traits In Genetically Remote Hybridization of Cotton

Cotton is the most important fiber and oil crop in Uzbekistan. But, most of Uzbek commercial varieties have a narrow genetic base. We are now interested in developing new varieties with a diverse genotype. The objective of our research is developing cotton breeding material with high (+)-gossypol in seeds for feeding non ruminant animals and combining this trait with superior fiber quality and agronomic traits. W now report results of studying inheritance and variability of such agronomic traits as fiber length, lint percent, weight of 1000 seeds, and yield among hybrids developed in this study. We found that most of the investigated traits are inherited as over dominance and intermediate type in F1. We observed broad positive and negative recombinants among the segregation populations of F2-F3. Specific inheritance characteristics will be reported for the lines we are developing for high (+)-gossypol in seeds and with superior fiber quality and agronomic traits suitable for the environmental growing conditions in Uzbekistan.
