Effect of recurrent and alternate mutagenic treatments in rice

Abstract

The effects of repeated mutagenic treatment in the M2- and M3- gene. ation* in rice are reported. Recurrent irradiation with gamma rays and alternate treatment with gamma rays and NMH, neither increased the sensitivity of seeds r enhanced the frequency of induced chlorophyll mutations. This indicate that e inspite of its secondary polyploid nature behaves like a diploid in its reppo to the action of mutagens.
