The seeds of two soybean cultivars viz., Pusa-16 and PK-1042 were treated with 15, 30, and 45kR of gamma rays, three concentrations of ethyl methane sulphonate (EMS) (0.1%, 0.2%, and 0.3%), and their combinations. Various morphological mutants were recorded in M2 and M3 generations. These morphological mutants were named on the basis of the part of the plant body affected. Eight different morphological mutants, i.e., tall, dwarf, gigas, black pod, smooth pod, black spotted seed, bold seeded, and early maturing were isolated. Among them, early maturing and bold seeded mutants had the potential to be incorporated into breeding programs. |
