A study was conducted in ricebean [Vigna umbellata (Thunb.) Ohwi and Ohashi] at Department of Organic Agriculture, CSKHPKV, Palampur to assess the extent of heterosis for eleven characters including grain yield per plant. Six lines and two testers were crossed in line × tester mating design to develop 12 F1 hybrids. The analysis of variance revealed considerable genetic differences among the genotypes. The variance due to parents was significant for all the traits except pods per cluster whereas variance due to crosses was significant all the traits under study. The variance due to parents vs hybrids was also highly significant for all the traits. | Heterosis studies for seed yield and earliness in intra-specific hybrids of ricebean [Vigna umbellata (Thunb.) ohwi and ohashi] an under utilized pulse
