Abstract: The aim of the current study is investigation of multiple leaflets in mungbean and to study the effects of multiple leaflets to the desirable quantitative characters through correlation studies. Two multiple leaflet mutants were obtained from γ-irradiation and used to study correlation with the agronomic features. The higher doses of gamma ray irradiation in mungbean will provide enough scope to develop a wide range of variation in many desirable characteristics like increase in leaflets/leaf and variation in shape and size of leaf lamina. Increase in multi-foliation may increase the biomass production, which could make a positive impact on seed yield by increasing the transfer of assimilate from source to sink. Most of the variation in the lamina shape was observed in the trifoliate leaves of higher doses of gamma ray irradiation, which turned into tetrafoliate or pentafoliate with much variation in shape and size and lamina like crumpled, lanceolate, ovate, lobed were observed in both the varieties. Observation of mutants like multifoliate may be progressed in the M2 generation through directed selection and these stable mutants might be used as donors for restructuring mungbean genotypes. Higher values for phenotypic and genotypic coefficient of variability for number of leaves suggest that there is a possibility for improving seed yield through direct selection for number of leaves with pods/plant and plant height.
