The study herein determines the available variability among the unexplored common bean germplasm based on morphological parameters. The collection of one hundred and thirty five genotypes was done and the experimental data for nine phenotypic yield attributing traits was recorded in the experimental field of SKUAST Jammu, Main Campus, Chatha for the two years. The field experiment was laid out in Randomized Block Design and the observations were recorded from six randomly selected tagged plants. The analysis of variance of pooled data depicted remarkable variability among the genotypes for all the characters studied. The observations showed that the genotypes namely K12 (Bandipora) were early maturing, N3 (Nishat) had the longest pod, R3 (Rajouri) exhibit the largest pod width, MT6 (Marmat) had the maximum value of seed weight and that the genotypes namely P3 (Poonch), KS6 (Shopian), VLR125 (Almora, Uttarakhand) showed the highest yield. Comparatively higher values for seeds per plant and pods per plant parameters were noticed in the genotypes belonging to Almora (VLR-125), Poonch (P11), Shopian (KS1 and KS6), Marmat (MT5) and Uganda (UG5, UG6, UG9 and UG11) region. Further, the pods per plant, seeds per plant, 100 seed weight and seed yield per plant traits depicted higher estimates for PCV, GCV and genetic advance presenting great scope for accelerating the crop improvement. Based on these preliminary results, the elite diverse genotypes can be selected for future breeding programs thereby enhancing yield in common bean. | Variability estimates for yield determining characters in common bean (Phaseolus vulgaris L.)
