Biometrical relationship of some quantitative and qualitative traits in upland cotton
2007
Correlation studies in four cotton advance strains viz., AENS-18/87, AENB-1-85, AEM-52 and AEH-731 were carried out. The objective of the study was to develop direct or indirect relationship among the quantitative traits for ultimate improvement in yield. Results revealed that the yield being a polygenic character highly depends on the number of bolls per plant and boll weight. Number of bolls per plant was highly significantly correlated with the yield. Whereas, highly significant correlation between boll weight per plant and yield per plant was recorded in the strains AEM-52 (r = 0.57**) and AEH-731 (r= 0.47**) which suggested that more the number of bolls and boll weight, the higher would be the yield per plant. However, the quality traits showed negligible negative to positive association with the yield per plant, revealed the fact that by improving the yield related traits would have least effect on characters.
