Study of heterosis in hybridization of geographically distant gossypium varieties

In the study, hybridization was carried out between the local Gossypium variety and geographically distant Gossypium varieties to obtain a selection starting material. To determine the effect of heterosis, hybrids obtained from the crossing of Ganja-110 Gossypium variety with geographically distant cotton varieties were studied, F1 generation hybrids showed a positive dominance in terms of growing season. The fiber yield of F1 hybrids of Ganja-110 × Selekt hybrid combination was the dominant hereditary character. In F1, the mass of raw cotton obtained from one cocoon was close to the parent form with a larger cocoon in hybrids obtained for all combinations. F1 hybrids were superior in fiber length compared to their parent forms. In the F1 hybrid offspring, all combinations were close to the parent form with high fiber length. The individual samples collected according to the characteristic shown in F3 were higher than the parent form, and sometimes closer to the parent form with higher fiber length. The individual samples collected from the hybrid seeds studied in the experiment were quite effective.
