用６０Ｃｏγ射线辐照甘薯品种高系１４号和栗子香的胚性悬浮细胞，辐射剂量为５～２５Ｇｙ。将辐照后的胚性悬浮细胞进行培养，获得了大量再生植株，即辐照后代Ｍ１Ｖ１。将这些辐照后代移植于大田，对其主要形态特征和经济特性进行了调查。结果表明，辐照后代在叶形、叶色、薯皮色、薯肉色、干物率及食味等性状上发生了明显变异，获得了薯皮色同质突变体和一批干物率高或者食味优的突变体
The 60Co γ-rays were used to irradiate the embryogenic suspension cells of sweet potato variety “Gao-xuan 14” and chestnut fragrant with radiation dose of 5 ~ 25Gy. The irradiated embryogenic suspension cells were cultured, and a large number of regenerated plants were obtained, that is, the irradiated offspring M1V1. These irradiated offspring were transplanted to the field and their main morphological and economic characteristics were investigated. The results showed that there were significant variations in the leaf shape, the leaf color, the potato skin color, the flesh color, the dry matter rate and the taste and taste of the irradiated offspring. Mutant mutton kiwifruit and a group of dry matter rate or taste good Of the mutant
