Path analysis studies in dolichos bean (Lablab purpureus L.)

Abstract

The investigation was laid out on thirty one genotypes of Dolichos bean (Lablab purpureus) in RBD with two replications during Kharif 2017 at the Experimental farm of Department of Agril. Botany, VNMKV, Parbhani. The observations was recorded on twelve characters viz. Days to first flowering, days to 50% flowering, length of inflorescence (cm), number of flowers per inflorescence, number of pods per inflorescence, days to first pod harvest, pod length(cm), pod width(cm), no of grains per pod, mean pod weight(gm), pod yield per plant(kg), pod yield per ha(q). Green pod yield per plant was significantly and positively direct effect with 50 per cent flowering, length of inflorescence, number of grains per pod, pod yield per hectare and negative direct effect with days to first flowering, number of flowers per inflorescence, number of pods per inflorescence, first pod harvest, pod length, pod width, mean pod weight. Hence direct selection for these traits may lead to the development of high yielding genotypes of dolichos bean.
