Path coefficient analysis study in dolichos bean (Lablab purpureus L.)

Abstract

The path coefficient analysis which splits total correlated coefficient of different characters into direct and indirect effects on fruit yield per plant in such a manner that the sum of direct and indirect effects is equal to total genotypic correlated. The data revealed that 100 seed weight showed highest direct positive effect on green pod yield per plant followed by number of pods per inflorescence, days to last green pod harvest, pod length, days to first flowering, vine length, pod width and seed per pod. YBMV incidence % showed indirect effect on 100 seed weight, number of pods per inflorescence, pod length, pod weight, pod width, number of green pod pickings, vine length and number of seeds per pod.
