A core set of crop genetic resources are considered “first-look-sources” of trait-specific accessions for use in crop-breeding programs. Sixty-four core germplasm accessions of dolichos bean (Lablab purpureus L. Sweet Var. Lignosus) and two check entries were characterized/evaluated for five qualitative traits and seven quantitative traits at the University of Agricultural Sciences (UAS), Bengaluru, India, during the rainy seasons of 2012 and 2014. Substantial variability among the accessions for quantitative traits and polymorphism for qualitative traits were documented. The germplasm accessions could be grouped into six clusters following model-based K-means clustering approach. The quantitative trait means and variances of accessions distributed among the clusters differed significantly. The accessions superior for six productivity traits were identified. The accessions, such as GL 142, GL 527, GL 110, GL 447, GL 576, KA, FPB-35, GL 441, GL 12, and GL 66, were promising for multiple quantitativ...
