Genetic variability and yield components of yard long bean (Vigna unguiculata var. sesquipedalis L.)

Yard long bean (Vigna unguiculata var. sesquipedalis L.) is one of the important leguminous vegetables in Bangladesh. However, yield this vegetable much lower Bangladesh compared to other yard beangrowing countries. Therefore, it crucial improve vegetable. In present study, genetic variability, heritability, character association and diversity were evaluated on randomized complete block design with three replications among seven-yard-long genotypes. The genotypes significantly variable for studied characters. High genotypic phenotypic coefficient variation was observed number pods per plant pod plant. Accordingly, high heritability together advance percent mean plant, diameter hundred seed weight. correlation studies revealed that showed significant positive pod, while negative days marketable harvest at both level. Path analysis first flowering, maturity, weight seeds had direct effect clustered into 3 groups highest inter-cluster distance between cluster I III lowest II III. exhibited higher performance traits including
