Abstract: Coriander (<em>Coriandrum sativum </em>L.) is an annual herb, mainly cultivated for its fruits as well as for the tender green leaves. It is native of the Mediterranean region. In India, it is grown in Andhra Pradesh, Tamil Nadu, Karnataka, Rajasthan and Madhya Pradesh. Research waconducted for studying the induced mutation in Coriander two types viz., CO 3 and K selection (Sn-K) were selected. Based on sensitivity studies, four doses of gamma rays (10, 15, 20, 25 kR ), four doses of EMS (10, 15, 20, 25 mM) and four doses of combination treatments (10 kR + 10 mM, 10 kR + 15 mM, 15 kR + 10 mM, 15 kR + 15 mM) were attempted. There were differences in the germination percent among controlled, pot studies and field conditions in both the varieties in all treatments. This indicated that the germination response is not only dose, mutagen and genotype dependent but also, affected by the prevailing environmental conditions.
