ANALYSIS OF VALUE-ECONOMIC CHARACTERS OF COTTON INTROGRESSIVE HYBRIDS IN DIFFERENT SOIL-CLIMATE CONDITIONS IN UZBEKISTAN

Abstract

Have been achieved the certain results on the development of varieties resistant to stress factors and recommendation to the agricultural industry because of the being of ecological unsustainable regions. Development of capability potential of adaptable valued hybrid traits, genotype and environmental effect, their relation with productivity, other valuable-economic traits and new high adoptive varieties has an important role. Double factorial dispersion analysis is carried out in the hybrid combinations of F2-F4 with the aim of determining the effect of genotype and environment on the forming of traits and interactions. The value of P in the double factorial dispersion analyze of the productivity of F4 hybrid combination was high than 0.05 and it does not conform the genotype’s effect, share of environment effect on the trait variation was reliable and made of 28.2%.
