摘要
配子体基因Ga控制着玉米的杂交不亲和性,杂交不亲和性具有遗传隔离和防杂保纯的作用。本研究利用Ga基因对甜玉米种质资源进行改良,通过杂交、回交转育及混合花粉鉴定法,将配子体基因成功转育到甜玉米的优良自交系上,为甜玉米的遗传隔离和杂种优势利用奠定了基础。
Cross incompatibility in Zea mays is controlled by gametophyte gene （Ga gene）. The cross-incompatibility has the function of genetic isolation and keeping seed purity. In this study, the Ga gene was used to improve genetically sweet corn lines. Through mixing pollen and backcross method, the cross-incompatibility or Ga gene was transferred successfully into the sweet corn lines, which establishing the foundation of heterosis utilization.
