Gamma rays are often used on plants in developing varieties that are agriculturally and economically important and have high productivity potential, Gamma irradiation can be useful for the alteration of one or a few physiological characters Mutagenesis by means of gamma rays has played an important role in the producing new mutants with improved properties which can produce higher amounts of commercially important metabolites. Cowpea (Vigna unguiculate L. Walp) is one of the world’s dicotyledonous leguminous food crops and a major food crop of millions of people in the developing countries. The present programme was an attempt to study the seed germination test and morpho- physiological traits of cowpea seed treated by gamma radiation and Biochemical observation on Cowpea varieties treated with gamma radiation. Plant responses in terms of growth parameters, leaf characters were analyzed. The result indicated an improvement in growth performances of cowpea varieties under gamma radiation.
