Abstract:

Pulses are rich and the cheapest source of delivering protein and also valuable animal feed. Indian has the largest area of about 34% and total production of about 26% of pulses globally. The present investigation was carried out with four parents in Diallel mating design during 2010-2011. The resultant 12 hybrids and four parents were evaluated in a randomized and replicated trial for estimating with regard to seed yield, correlation, path analysis and YMV resistance. The study on association of different traits indicated that single plant yield was highly correlated with plant height, number of branches per plant, number of pods per plant, pod length and number of seeds per pod. Path analysis revealed that pod length followed by number of pods per plant and number of branches per plant will be effective in increasing the yield. The inheritance of YMV was studied with 12 hybrids, among the hybrids, VBN 4 x VBN 2, VBN 2 x VBN 4 and VBN 2 x LBG 17 showed complete resistance against YMV, hence the crosses were recommended for further breeding programme to identify high yielding YMV resistant lines.
