Among the groundnut varieties, TAG-24, TG-26, TG-37A in normal seed class and TKG-19A and TPG-41 in large seed class, have become popular among the farming community in India. As a first step to transfer the benefits of these varieties to the farmers, large-scale breeder seed production programmes were undertaken by involving several national institutes and state agricultural universities.

Farmers have been realizing the high-yielding ability of groundnut varieties by harvesting record groundnut yields in many parts of the country. By cultivating these mutant varieties, groundnut productivity in major groundnut states like, Gujarat, Andhra Pradesh, Maharashtra, Karnataka, Orissa and Rajasthan has been increased. A drought tolerant variety, TG-37A has rekindled groundnut cultivation in desert areas of Rajasthan state. Unlike the existing large seed varieties with long duration, the recently released large seed mutant varieties like TPG-41 and TLG-45 benefited many farmers, traders and exporters by virtue of their earliness, moderate seed dormancy and superior productivity.

In mungbean, BARC has made major breakthrough in developing disease resistant varieties. TARM-1, TARM-2 and TARM-18 were released for the first time with resistance to powdery mildew disease for southern and central zones of India. TMB-37 has been released for summer season, having early maturity (<60 days) and yellow mosaic disease resistance that made available an additional area for mungbean cultivation under crop diversity programme. Another mungbean variety TJM-3 is the first variety with multiple disease resistance for powdery mildew, yellow mosaic virus and Rhizoctonia root-rot diseases. The recently released mungbean variety TM-96-2 suitable for rice fallow cultivation in India is endowed with powdery mildew resistance and synchronous maturity. Blackgram mutant varieties TAU-1 and TU- 94-2 are very popular varieties in central and southern zones of India. TAU-1 is cultivated over majority of blackgram growing areas of Maharashtra. The recently released pigeonpea variety TJT-501 is garnering huge demand in Madhya Pradesh. The majority of the mutant varieties not only has benefited the Indian farming community, but is also being used as genetic resource material in national/state breeding programmes of crop improvement.
