A study was undertaken in a cowpea (Vigna unguiculata
(L.) Walp.) variety CO 6
to assess the efficiency and effectiveness of chemical
mutagens; ethyl methane sulphonate (EMS), diethyl sulphate
(DES) and sodium azide (SA). EMS treatments were found
highly effective than the other chemicals. Mutagenic
effectiveness and efficiency decreased with increase in all
mutagenic treatments.
Key words:
Cowpea, mutagens, ethyl methane sulphonate, diethyl
sulphate, sodium azide. |
