Yard long bean is an important vegetable crop that supplies the dietery protein through the edible tender pods. The twelve genotypes of yard long bean from different locations of the country were collected and analysed for studying their variability and diveregence. Mean performance and the estimates of GCV and PCV of the yield contributing traits were worked out to analyse the variability. The highest yielder was Acc 18 (Puthuppady local). On the basis of Mahalanobis D2 statistics, the genotypes were grouped into five clusters. Study of the genetic divergence in the genotypes revealed the genetic distance between the genotypes. Genotypes from divergent clusters can be selected for hybridisation programme to get desirable recombinants.

Keywords: Yard long bean, Variability, Genetic Divergence, Clustering of genotypes
