摘 要 ：用~(60)钴γ-射线辐照易感甘薯黑斑病的徐薯18品种,在 M_1V_3获得了5个高抗黑斑病的无性系突变体,在后代群体中也出现高感无性系,因此借助于辐照从优良遗传背景但不抗黑斑病的材料中,有可能得到具高产潜力、优质和抗病的新品种。有关生长缓慢和皮色镶嵌等突变多发生在 M_1V_1,在 M_1V_2或 M_1V_3进行选择常常能得到经济性状较

Abstract:Xu-18,a variety susceptible to black rot 〔Ceratostomella fimbriata(Ell.et Hals)Elliott〕,was irradiated with gamma ray from a ~80Cosourc.Five clonal lines highly resistant to black rot were obtainedin M_1V_3,althongh there Were also highly susceptible lines in the progenypopulation.It is therefore
