Six genotypes as lines and two genotypes as testers of ricebean were studies in line x tester analysis. The study revealed that the gene action involved in controlling characters namely, days to flowering, days to maturity, plant height, branches per plant, pods per plant, clusters per plant, pods per cluster, seeds per pod and yield per plant was non-additive gene action while two traits namely, 100-seed weight and pod length was under the control of additive gene action. Genotype RBHP-38 and RBHP-43 were found to be good general combiner for earliness and for determinate habit RBHP-38 and RBHP-108 were found to be top ranking general combiners. None of the testers found good general combiner for all the characters. The cross RBHP-36 x PRR-2007-2 recorded significant negative sca effects for days to flowering, days to maturity and plant height indicating earliness and determinate habit. The crosses RBHP-36 x RBHP-900 and RBHP-61 x PRR-2007-2 recorded positive significant positive sca effects for branches per plant, pods per plant, clusters per plant, pods per cluster and yield per plant. These crosses could be further exploited to obtain transgressive segregants in the breeding programme.
