Abstract
Vigna radiata (L.) Wilczek is an important legume crop in India for Food as well as Fodder Purpose, enriched with good Proteins, Carbohydrates, Vitamins and Minerals. The demand of Vigna radiata is high in market today, so there is a need to enhance the productivity and area under cultivation. The Mutation Plant Breeding is the most popular, widely used and globally accepted method to improve the cultivars for high yield, early maturity, drought, salinity, heat, insect, disease tolerant/resistant, high nutritional and low antinutritional factors. Mutagens like; Ethyl Methane Sulphonate, Sodium Azide, Gamma Irradiation are used in Mutation Breeding to create variability. The present study has been carried out on the Vigna radiata, Cultivar-Naval. The first stage in the research was the determination of LD50 Value of the Cultivar Naval. It was carried out with different concentrations and time of intervals with mutagens like; EMS, SA and GR with including control as nil (without treatment). The parameters were studied in accordance with the International Seed Testing Association (ISTA) rules. The results showed variation in the studied parameters as compared to control.
Highlights
Vigna radiata (L.) Wilczek (2n=22), is the member of Leguminosae family, cultivated throughout the world including India, Pakistan, China, Nepal, Bangladesh, Myanmar, Malaysia, Thailand, Indonesia and Srilanka
Vigna radiata is cultivated throughout the year, i.e. Kharif, Rabi and Summer season

Summary
Vigna radiata (L.) Wilczek (2n=22), is the member of Leguminosae family, cultivated throughout the world including India, Pakistan, China, Nepal, Bangladesh, Myanmar, Malaysia, Thailand, Indonesia and Srilanka. India is the largest producer in the world to cultivate Mungbean. The area under Mungbean Cultivation is increasing in the world. Rajasthan with more than 42 percent area and 39 percent of production in the total mungbean contribution in the country. The cultivar Naval is commercially and widely cultivated in Maharashtra. It is not suitable in summer season, susceptible to drought and salinity. The effect of Mutation rates depends on the dose of that chemical concentration and time for soaking which is applied on seed material. This study was carried out to determine the LD50 of Vigna radiata Cultivar-Naval. In M2 Generation mutation frequency of Chlorophyll mutants and Leaf morphological changes should be observed. The final percentage of seed germination and parameters were calculated using formula
