Correlation between family and range value economic traits in cotton
Abstract
Abstract It is stated that interdependence is the main feature of the heredity of quantitative traits of cotton and other agricultural plants. Clearly, the dependence of traits is explained genetically in two ways: pleiotropic effects, in which a change in one gene causes changes in several traits, and gene fusion. In this research, it was aimed at investigating correlation between family and range value economic traits in cotton. For this research, laboratory and field experiments were undertaken towards taking results and doing correlation analysis. According to the research results, it was appropriate to use O-609-610, O-105-108, O-117-120 families and T-482-483/07 T-814-815/07 lines in practical selection. However, it was necessary to continue the research on achieving moderate and strong correlations from the weak level of negative correlation (in this place (-) is considered appropriate). Compared to the convergent hybrids obtained on the basis of the transgressive recombination principle, convergent hybrids obtained by the combined transgressive recombination principle and incomplete recrossings have been found to have relatively high ripening speed, wilt tolerance and fiber quality indicators.
