Induction of determinate growth habit in Winged bean (Psophocarpus tetragonolobus (L) DC)

The breeding behavior of selected mutants indicated inconsistent segregation pattern. All these results showed high frequency of mutation, non Mendalian segregation ratio for various mutant characters. The genotypic differences appeared to be more important than the differences in mutagenic treatments. Twenty eight mutants were observed in M₂ generation of IC-26345 genotype. Out of more than 900 plants screened for dwarf plant type, only two plants showed semi dwarf types in M₂ generation due to 20 kr gamma radiation treatment.
