Mutation breeding in crop plants is an effective approach in improvement of crop having narrow genetic base such as Bhendi or Okra (Abelmoschusesculentus (L)moench). The main objective of the present study is to determine the effect of different concentration of ethyl methane sulphonenate (EMS) and colchicine. In Mahyco hybrid, colchicine (0.4, 0.6 and 0.8 percent concentrations) and EMS (0.8 percent) and in TCR 2086 variety (Col 0.4, 0.6, 0.8 percent) EMS (0.8, 1.0, 1.2 percent). The observations were recorded in M2 generations of different morphology and yield characters such as plant height, number of branches per plant, number nodes per plant, fruit length, fruit girth, number of fruits per plant, number of seeds per fruit, fruit weight and fruit yield per plant. In M2 preplanning Mahyco hybrids and TCR 2086. Significant increase in colchicine treatment which compound to EMS for most of yield and its component traits.
