ABSTRACT

A mutagenesis programme was undertaken using ethylmethane sulphonate (EMS), methylmethane sulphonate (MMS) and Sodium azide (SA) on cowpea varieties RC-19 and RC-101. Progenies were advanced to M4 generation with an objective to determine effectiveness of selection exercised on high yielding progenies during M3 generation. For this purpose, a comparison of individual M4 progenies with the mean of their bulk progenies was made and found that progeny number 27-6-10, 36-5-2,36-8-8 and 37-3-10 of RC-19 and progeny number 92-2-9, 119-3-1,112-1-10 and 128-4-5 of RC-101 were significantly superior than their respective bulk and control population for seed yield per plant. This indicated that selection was effective in M3.
