Irradiation Induced Mutations of Embryogenic Cell Suspension Cultures and Production of Homogeneous Mutants in Sweet Potato, Ipomoea batatas (L.) Lam
Embryogenic cell suspension cultures of sweet potato cvs. Kokei No.14 and Lizixiang were irradiated with γray. The doses of irradiation ranged from 5 Gy to 25 Gy. The irradiated suspension cultures were cultured and gave large numbers of regenerated plants (M1V1). M1V1 plants were transplanted in the field, and variations of leaf shape, leaf color, root skin color, root flesh color, dry matter content and taste after steaming were observed in M1V1. The homogeneous mutants of root skin color and the m...
