Only two of 46 soybean varieties in India owe their development to mutations. Although mutations have been induced and isolated for several attributes, the impact of mutation breeding in soybean improvement has yet to be realized. An intensive mutation breeding programme using physical and chemical mutagens was initiated in soybean, followed by recurrent selection and evaluation. Promising mutants of practical utility are described, including a yellow seeded mutant ('NRC-1'), of the indigenous black seeded 'Bhat' variety, and 'NRC-2', a high seed germinability mutant of the 'Bragg' variety. Over the years, the 'NRC-2' mutant, in particular, has performed exceedingly well in multilocational trials in the northern hill zone of India. [AS]
