An analysis of chemical mutagenesis in rice (Oryza sativa L.)

Abstract:
The present investigation was carried out to study the effect of the chemical mutagen EMS in the popular rice varieties ADT 43 and ADT 45. The LD50 values of EMS were fixed as 0.6 per cent for ADT 43 and 0.8 per cent for ADT 45 which are suitable for inducing viable mutants. The widest spectrum of viable mutants like early, spreading, narrow leaf, lax panicle, long grain, awned grains and hairy grains were noticed in the M2 generation. The mutagenic effectiveness was maximum at 0.8 per cent EMS in ADT 43. The mutagenic efficiency based on injury was maximum at 0.6 per cent EMS in ADT 43 and the mutagenic efficiency was maximum at 0.8 per cent EMS in ADT 43 based on lethality.
