Abstract

The present study investigated the effects of EMS on crop phenotypes on four mungbean varieties viz., Co (6), Co (7), VRM and VBM. The germination percentage was affected by EMS treatment with increase in dose or concentration of mutagen. The doses can be determined by establishing the LD 50 value for the mutagen to be used. The expected LD50 values of EMS for Co (6), Co (7), VRM 1 and VBM 3 are 37.15, 39.81, 28.18, 32.35 respectively. Several plant traits like germination percentage, survival percentage, root length, shoot length, was affected with the mutagenic treatments. Co7 shows better germination and survival percentage compared to other genotypes. Hence Co7 chosen for establishment of TILLING population.
