Character Association and Path Analysis Studies in Pole Type Dolichos Bean (Lablab Purpureus L.)

Character association between yield and its component characters as well as path analysis of thirty seven pole type dolichos bean (Lablab purpureus L.) genotypes were studied during kharif 2013. The genotypic correlation coefficients were higher than phenotypic correlation coefficients for all most all characters under study. Number of pods per vine, pod length, pod width and average weight of 10 pods showed highly significant positive correlation with green pod yield per plot. Path analysis indicated that number of pods per in florescence, number of pods per vine, days to 50 per cent flowering and weight of 10 pods had positive direct effects on green pod yield. These traits could therefore be useful for yield improvement program of pole type dolichos bean.
