Studies were undertaken to obtain precise information on the effects of
six doses of gamma rays (5 to 30 krad) and seven concentrations of ethyl methanesulphonate
{0.1 to 0.7 per cent) on cowpea.
Gamma ray and ethyl methanesulphonate treatments resulted in physiological
damages in M, generation as evidenced by the reduction in survival of
plants, plant growth and fertility. Mutation frequency estimated on M, plant
basis increased with increasing doses of gamma rays and ethyl methanesulphonate.
Effectiveness of gamma rays increased with increasing doses upto 15 krad and
there was a reduction at still higher doses. Most efficient gamma ray dose was
found to be 10 krad when efficiency was estimated on the basis of lethality or
sterility, while on injury basis 30 krad was the most efficient dose. Among the
different doses of ethyl methanesulphonate tried, 0.4 per cent was the most effective
as well as efficient, irrespective of the criterion adopted for the estimation of
efficiency. |
