Mutagenic Effect of Gamma Ray, Ethyl Methane Sulphonate and Sodium Azide on Seedling Height and Survival of Sunflower [Helianthus annus L.]

Seeds of sunflower [Helianthus annus L. ] Bhanu& 55-56 were treated with various concentration of Gammaray [10kR, 20kR, 30kR] Ems [0.05 %, 0.10 %, 0.15]& [0.01 %, 0.02 %, 0.03 %] respectively, For studying seedling height [Shoot& root] and survival percentage of plants. In this investigation found that when the increasing concentration of mutagenes the decrease seedling height in compair to control. The data on plant survival in the present studies indicate that the survival percentage decreases with increase the mutagenic treatment
