Effect of gamma rays and EMS on mutation frequency, mutagenic efficiency and effectiveness in M2 generation of chilli


Author(s): Dr. Sonali Ramaji Soyam

Abstract: Comprised effectiveness and efficiency of gamma rays and EMS for inducing mutation in chilli seeds were treated with gamma rays and EMS. The number of variants and mutation frequency was observed in each treatment in M2 generation. Mutation frequency as the frequency at which a specific kind of mutation was found in the population of cells or individuals. The frequency and saturation of mutations can be regulated by varying the mutagen dose and mutagenic agents can induce different extensions of genomic lesions, ranging from base mutations to larger fragment insertions or deletions. Mutagenic effectiveness reflects rate of mutation in relation to mutation dose, whereas mutagenic efficiency is the mutation rate in relation to lethality or biological injury. Lethality or biological injury based on germination, increased with increasing doses of irradiation and EMS. The maximum mutagenic efficiency and effectiveness was recorded in the lower doses of mutagenic treatments 0.2% EMS and 100 Gy gamma rays.
