Résumé partiel
Present investigation was undertaken in clusterbean to study variability, heritability, genetic advance, genetic divergence, correlation and path analysis. The experimental material consisted of 48 genotypes of clusterbean which were evaluated in dry land farm of S.V. Agricultural College, Tirupati in a randomized block design with three replications during kharif, 2014. The analysis of variance revealed significant differences among genotypes for all the traits. Among the genotypes, GA2G-0503 recorded maximum per se performance for seed yield per plant followed by MG-903 and GAUG-101. The genotype GA2G-0503 also showed higher mean values for number of pods per plant, endosperm percentage and gum percentage whereas the genotype MG-903 registered higher number of branches per plant, number of clusters per plant, number of pods per plant and pod yield per plant besides maturing early. GAUG-101 recorded higher values for number of branches per plant. The genotypes CH2G-0520, RGG-13-5, RGC-1066, RGC-936 and C214-01 could be recommended for high density planting because they were observed to be mainly single stemmed with no or least number of primary branches and the main stem was straight and were found to be lodging resistant. Number of branches per plant, number of pods per cluster, number of clusters per plant and seed yield per plant registered higher estimates of GCV and PCV there was more scope for selection
