Abstract:

Cowpea [Vigna unguiculata (L.) walp.]; also known as a black-eyed pea or Southern pea is self-pollinated crop belongs to the family Fabaceae. In this experimentation, thirty accessions were evaluated for eleven agro-morphological traits at agronomy instructional farm, C. P. College of agriculture, S. D. A. U., Sardarkrushinagar under high temperature using randomized block design (RBD) and three replications. Analysis of variance revealed significant variation for all the eleven agro-morphological traits under study. The genotypic coefficient of variation, heritability and genetic advance were observed highest for seed yield per plant followed by number of pods per plant and leaf area per plant. Significant positive correlation was found between seed yield per plant and number of pods per plant; number of seeds per pod; number of branches per plant; pod length and plant height. Whereas, negative significant correlation was observed between seed yield per plant with days to flowering and days to maturity. In the present studies pod length recorded the highest positive direct effect on seed yield per plant followed by number of branches per plant and number of pods per plant. While, days to flowering had highest negative direct effect on seed yield per plant. Both correlation and path analyses indicated that number of pods per plant, number of seeds per pod, number of branches per plant and pod length were the major direct contributors to seed yield.
