甜菜波型双_2不育系与保持系,是我们利用波型不育系为母本与双丰二号为父本测交和连续回交进行核置换转育出来的。在转育雄性不育系的研究过程中初步看出甜菜雄性不育常和双亲亲缘有宓切关系。 Beet wave type double _2 sterile line and maintainer line, we use the wave sterile line as the female parent and Shuang-Fung 2 as the male test and continuous backcross nuclear transplanting. In the process of transplanting male sterile lines, it is initially concluded that the male sterility of sugar beet is often related to their relatives.
