These genotypes were planted in Randomized Block Design with six replications during kharif season 2010-11 at Instructional Farm, Department of Horticulture, Rajasthan College of Agriculture, Udaipur. Analysis of variance indicated presence of considerable variability for all the 14 characters. High GCV and PCV were recorded for pod yield per vine, average pod weight and leaf area. High estimates of heritability along with high genetic advance as per cent of mean were observed for pod yield per vine and pod width. Therefore, these characters can aid in selection programme. The results from character association indicated that pod yield per vine had significant and positive correlation with stem diameter, number of branches per vine, average pod weight and number of pods per vine at both the levels. Path coefficient analysis revealed that characters viz., average pod weight, number of pods per vine, days to 50% flowering, number of flowers per cluster, days to maturity, number of pods per clusters, stem diameter and pod length had positive direct effect on pod yield per vine. Number of pods per vine, average pod weight, days to maturity and number of flowers per clusters showed high and positive indirect effect towards pod yield per vine. On the basis of mean performance the genotypes DL-14, DL-8, DL-2 and DL-12 were found superior in terms of high mean values of pod yield per vine. These genotypes may further be utilized in breeding programme aimed at improving pod yield per vine in Indian bean. All those characters which showed positive direct effect towards yield proved effective in enhancing productivity level in Indian bean.ennullThesis
