ABSTRACT
An investigation on variability for dry pod yield and other component characters such as seed gum content, number of dry pods per plant, number of clusters per plant and number of pods per clusters was carried out in 67 cluster bean genotypes at College of Horticulture, Bagalkot, during summer 2011. All the characters studied had shown highly significant (at P=0.01) difference. The characters, viz., dry pod yield, number of dry pods per plant and number of cluster per plant recorded high estimates of genotypic and phenotypic coefficients of variation indicating ample scope for selection of genotypes from available germplasm. Based on this, some of the promising genotypes identified in the genetic stock are HG-04-875, Pusa Navabahar, HGS-881, RGC-1025, IC 3773 for dry pod yield per plant. Seed gum content showed moderate to low estimates of PCV and GCV. Thus, for improvement of this trait there is need for creating variability through introduction and hybridizing the diversified genotypes to generate transgressive segregant.
