Background: Induced mutagenesis was employed in horse gram cv. CRIDA 1-18R with an objective of evolving mutants with increased yield potential. Methods: Based on preliminary study, the variety has been irradiated with desirable doses of gamma rays (200 Gy and 300 Gy), electron beam (100 Gy and 200 Gy) and its combination (100 Gy) and the material were forwarded to M2 generation following parentprogeny row basis. The genotypes exhibiting superior yield than control were further forwarded to M3 generation. Multivariate analyses were performed to determine the induction of micro-mutants for 11 quantitative traits. Result: The reduction in mean value over control was observed for most of the yield component traits at M2 generation. Among the mutagenic treatments, combination of gamma rays with electron beam registered high mean values for pod length (5.05 cm), number of pods per plant (54.42) and single plant yield (25.68 g) at M3 generation. Non-significant skewness and / or kurtosis at M3 population denoted the absence of epistatic interactions for plant yield. An increase in variability pattern, H2 and GAM at M3 generation indicated the scope for trait (plant height, number of seeds per pod, number of clusters per plant, number of pods per plant, biological yield and single plant yield) improvement through selection.
