甘薯是完全的(尽管有部分变异)同源六倍体,有很强的自交和杂交不亲和性。自从Miller首次报道了X射线诱发甘薯突变体以来,相继发表了许多论文。我们正在进行下列三方面的研究:1.突变形成的方法;2.直接利用数量和质量性状得到改善的突变体;3.辐射在杂交育种上的应用。 Sweetpotato is a complete (albeit partially variant) hexaploid with strong selfing and hybridization incompatibility. Since Miller first reported X-ray-induced sweet potato mutants, many papers have been published. We are conducting the following three aspects of research: 1. Methods of mutation formation; 2. Direct utilization of mutants with improved quantitative and qualitative traits; 3. Application of radiation in crossbreeding.
