我国甜菜雄性不育选育工作,历经6—10年的时间,陆续培育出一批甜菜雄性不育系及保持系,并配制出数百个杂交组合,其中有些组合表现出明显的杂种优势,这些都是可喜的成绩。但是,也出现了一些问题,比如个别甜菜雄性不育系的育性不稳,一些不育系的不育株率有所下降,在选育的理论和某些技术方面还存在一定的盲目性。至此,初 China’s sugar beet male sterile breeding work, after 6 to 10 years time, one after another to cultivate a group of sugar beet male sterile lines and maintainers, and the preparation of hundreds of hybrid combinations, some of which showed obvious heterosis, These are gratifying results. However, some problems have emerged, such as instability of individual sugar beet male sterile lines, the decline of the number of sterile lines in some CMS lines, and some blindness in the theory of breeding and some techniques . At this point, early
