ABSTRACT
Semi dent maize (Zea mays) variety EV-6098 was treated with different concentrations of chemical mutagens namely, Diethyl Sulphate (DES), Ethyl Methane Sulphonate (EMS) and Ethylene Imine (EI). To do mutations, various concentrations such as 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110 and 120mM for 5 hours were subjected to 300 seed sample of each concentration and with one respective control. The LD50 was observed in 60mM of EMS, 50mM of DES and 50mM of EI. The physiological, morphological and different yield attributes were mainly decreased seed germination percentage, seedling survival ratio, days to first tesseling, days to first silking, plant height, number of leaves per plant, number of ears per plant, number of seeds per ear, ear length, and width, 100 seed weight, seed yield per plant, fresh weight per plant and dry weight per plant. The rising concentration of the EMS, DES and EI resulted in reduced physiological and yield attributes have been concerned with chromosomal abnormalities caused to the cell of the maize plant affected by chemical mutagen.
Key words: Zea mays, Diethyl Sulphate (DES), Ethyl Methane Sulphonate (EMS), Mutagen
