Abstract: In the present investigation ten F1 hybrids of grass pea and their 5 parents were evaluated in a randomized complete block design in three replication to estimate combining ability of genotypes by using Half diallel mating design for the yield and yield contributing characters during the Rabi December 2017-2018. Combining ability analysis indicated contribution of non-additive gene effect playing an important role for most of the characters and the analysis of variance due to general combining ability (GCA) and specific combining ability (sca) revealed highly significant for most of the characters. The parent, Prateek was recorded as the best general combiner for seed yieldplant-1 and seed protein content while, for pods plant-1, seeds pod-1, seeds plant-1 and low ODAP in both seed and flour, Siraha Local was observed as the best general combiner. In the crosses, Ratan x RLS 3004 and Prateek x Siraha Local proved to be the best specific combiner for seed yield plant-1 and other related traits.
