Popis:	The study was conducted on 56 cluster bean genotypes to study the linear combination of characters associated with pod yield. Correlation, path analysis and selection index were studied for pod yield using the characters viz., plant height at final harvest (cm), days to 50% flowering, average weight of 50 pods (g), pod length (cm) and protein content of pods. The genotypic correlation coefficients were higher than phenotypic correlation coefficients for all the characters studied. Plant height displayed high positive direct effect on pod yield per plant. Average weight of 50 pods, pod length and protein content of pods exhibited low positive direct effects on pod yield per plant. The index value for each genotype was determined and the genotypes were ranked accordingly. The highest value was recorded in check Pusa Navbahar followed by MDU-1, Chitra Gold, IC-51063 and IC-522421. These genotypes were identified to be genetically superior.
