Abstract

In the M2 populations of different soybean varieties irradiated with gamma rays, a total of seven lines showed segregation for sterility at maturity. The detailed genetic and cytogenetic studies of these lines were conducted in M3 and M4 populations derived from fertile segregates of the M2 progenies. Four of these were found to be both male and female sterile, whereas, three of these showed female fertility but male sterility as indicated below (Table 1).
