Trait Association Studies in Early Segregating Generations of Cowpea [Vigna unguiculata (L.) Walp]

Background: Cowpea is a major pulse crop in India. Developing cowpea cultivars with high yield and sustainable protein content contributes to food nutritional security. Hybridization followed by careful selection of genotypes from the early segregating populations may produce final cultivar coupled content. Methods: The genetic material used present investigation were derived crosses three i.e., H10 (Anaswara x PKB 3) H11 4). evaluated Department Plant Breeding Genetics, Kerala Agricultural University, Thrissur during season 2015-2017. Trait association based on correlation path analysis was carried out phenotypic data F2 F3 generations crosses. Result: In generation cross H10, number pods per plant seeds pod displayed significant positive seed plant. 100-seed weight exhibited H11, pods, length, single weight, revealed significant1 generations. On analysis, various quantitative characters showed direct effects yield. Selection segregants contributing likely be desirable for improvement cowpea.
