利用遗传突变基因改良特用玉米 Ⅴ.甜玉米胚乳突变基因的效应与利用

Application Genetic Mutant Gene for Improvement of Particular MaizeV. The Effects and Application of Sweet Corn Mutant Gene

简要说明甜玉米突变基因由来以及研究近况。甜玉米在碳水化合物中形成的隐性突变基因占有相当大的比例,其种源丰富,已育成多个品种。在育种技术方面,着重介绍新方法——转座子育种技术。

This paper presents origin of sweet corn and the recent research development in this area. The proportion of recessive mutant genes of sweet corn formed in carbohydrate is considerable high with abundant germphasm resources. Many hybrid sweet corn have been breeded. New technology of breeding method, the transposable element tagging, is detailed.
