Genetic variability has been greatly valued in yard-long bean, due to their narrow genetic base. To diversify the genetic base, yard long bean genotypes were evaluated to quantify the variation, to assess the extent of association between the yield complaint traits, diversity and for their utilization in crop improvement programmes. High phenotypic and genotypic coefficient of variations, heritability coupled with genetic advance over mean were observed most of the traits except internodal length, days to first and 50 per cent flowering, days to first and last picking, seeds per pod. Correlation and path analysis of variables namely pod length, pod width and pods per plant contributes high positive significant association with pod yield per plant, and maximum direct and indirect effect recorded for pods per plant, green pod length and green pod width. The genotypes were grouped into 12 clusters, the maximum divergence recorded between genotypes of Cluster XI and Cluster XII for traits pod yield per plant, vine length and yield per plot and pod length contributed high towards total divergence, the genetically diverse genotype of these clusters aids in the creation of larger recombinants, and would be an aid in the genetic improvement of yard-long bean genotypes.
