Abstract: A study was undertaken to identify contrasting accessions for pod productivity traits from a core set of dolichos bean germplasm. Among different combinations of phenotypically contrasting accessions for pods plant-1, highest numbers of SSR markers were polymorphic between GL 577 and KA followed by GL 577 and GL 142. Similarly, between GL 201 and GL 527, which are contrasting for fresh pod yield plant-1, eleven SSR markers, were found polymorphic. Nine SSR markers differentiated two pairs of genotypes GL 201 and KA and GL 355 and GL 576 which were contrasting for fresh seed yield plant-1. These quantitative traits and SSR marker alleles-based diverse genotypes could be used as putative parents for developing mapping population to identify QTLs controlling yield associated traits and/or could be used to effect crosses to derive superior pure lines for use as varieties for commercial cultivation of dolichos bean.
