Abstract: Seeds of 2 varieties viz., major and minor of Vicia faba L. were subjected to 4 different concentrations i.e., 0.1, 0.2, 0.3 and 0.4% of Ethyl Methane Sulphonate (EMS). Meiotic studies were carried out in the control as well as in the treated materials. Different types of meiotic abnormalities such as stickiness, univalents, multivalents, unorientation of chromosomes, precocious separation of chromosomes at metaphase, bridges, laggards and unequal separation of chromosomes at anaphase were recorded. In general, the meiotic abnormalities in both the varieties increased along with the increase in concentration of mutagen. However, Vicia faba L. variety minor showed more chromosomal abnormalities as compared to Vicia faba L. variety major at the same treatment.
