Genetic analysis of quantitative traits in Blackgram using line x tester design


Deekshitha Bomireddy, N Vinay Kumar, Tapas K Mishra, B Pradhan and KC Samal

Blackgram is one of the most important pulse crops. An investigation was carried out in blackgram to understand the gene action and to estimate the general combining ability (GCA) effect of parents and specific combining ability (SCA) effect of 15 crosses (involving five lines and three testers) for yield and its traits using Line x Tester analysis. The relative estimates of variance due to GCA were higher than SCA variances for most of the traits indicating predominance of additive gene action. Among the parents, based on GCA effects, Pant U-30, B-3-8-8 and LBG-787 were found to be good general combiners for yield and its contributing traits and can be used in future breeding programmes. Based on SCA effects, the cross, B-3-8-8 x Vamban 7 was identified as best specific combiner for no.of pods per plant and could be further exploited to obtain transgressive segregants.
