摘　　要：1991年在本院试验地种植的选自组合[门源×(Tobin×门源)F_1]F_6的白菜型春油菜双低品系88—523中发现了一株花叶不育株,此不育株的雄蕊呈戟形、无花粉,雌蕊稍弯曲。用几个不同品种(系)与其进行测交和回交,证明该不育属细胞质雄性不育,命名为88—533A细胞质雄性不育。用国内外的亲本材料与不育材料测交,结果表明,保持基因型易在青海和印度的常规品种中找到,而恢复基因则在加拿大的单双低油菜品种(系)中较易获得。One male sterile plant with curved leaf in double low line 88-533 was discovered in 1991.The expression of fertility in F1 and BC1 derived from crosses and backcrosses between several varieties and the sterile line indicated that male sterile line belonged to CMS,and it was named as 88-533 CMS.Various crossing experiments indicated that it was easy to find its maintainers in the spring B.campestris germplasm resources from Qinghai and India and its restorers would be obtained from the single and double low varieties from Canada.
