A mutagenesis programme was carried out using three
chemical mutagens viz., EMS, MMS and SA on two varieties
of cowpea [Vigna unguiculata (L.) Walp.] namely, RC 19
and RC101. The M1 generation was raised only from
higher doses of the mutagens which adversely affected
their survival. In M
2 generation, a wide spectrum of
macromutations were observed in the progenies of both
the varieties including few seed color mutants. The MMS
treatment was found most effective and efficient as well.
Several M2 progenies of the two cowpea varieties were
significantly superior to their respective parents for seed
yield per plant. A considerable number of M2 progenies
were consistently superior to their parents in M3 generation
also.
