TRAIT CORRELATIONS AND IMPLICATIONS FOR YIELD POTENTIAL IN COTTON: A COMPREHENSIVE STUDY

Abstract

Cotton (Gossypium spp.) yield improvement is a primary objective for breeders and researchers. This study explores trait correlations and their impact on cotton yield potential. Through field experiments and statistical analyses, relationships between traits and yield to provide insights for cotton breeding programs was investigated. Results revealed significant associations between traits and cotton yield. Plant height, number of nodes, monopodial branches and open ball showed positive correlations with yield. Taller plants, increased sympodial branches and more open balls were linked to higher yield potential. SS32 RH-668, NIAB-KIRAN and CIM-599 per form better among 19 genotypes. Further research is needed to establish causality. The study emphasizes that when selecting cotton genotypes for better yield potential, it's crucial to consider traits like sympodial branches, boll weight, open ball and green ball. Understanding their direct and indirect effects can help breeders develop varieties with desired characteristics and maximize yield. Additionally, the study found significant genetic variability among tested genotypes creating opportunities for breeding programs to enhance yield and desired traits. These findings offer valuable insights into trait correlations, paving the way for future research on genetics and the development of better cotton varieties to meet global demand.
