摘　　要：用大麦7条染色体标记性状的材料作父本,与自然突变雄性不育株90-0713和90-0732配置14个杂交组合。通过F_1和F_2代的性状表现研究雄性不育性的遗传和基因定位。各组合的F_1代均可育,F_2代的可育株和不育株的分离符合3:1的比例,表明雄性不育性受隐性单基因控制。90-0713的雄性不育基因位于第1条染色体上与红茎基因(Rs)连锁遗传,其交换率为14.46±1.88％,而90-0732的雄性不育基因则位于第3条染色体上与黄条纹叶基因(yst)连锁遗传,其交换率为30.58±4.19％。14 crossing combinations were mated with spontaneous male sterile lines'90-0713 and 90-0732'and the lines with tagged characters of 7 chromosomes of barley. The genetics and gene location were studied through F_1 and F_2 generations. F_1 plants of all combinations were fertile and the ratio of fertile and sterile plants in F_2 conformed to the theoretical ratio of 3:1, which showed that the male sterility was controlled by a single recessive gene. The male sterile gene of 90-0713 was located in the first chromosome and linked with the red stem gene(Rs) ,and that of 90-0732 was located in the third chromosome and linked with yellow streaked leaf gene(yst). The exchange rate were 14. 46+1. 88％ and 30. 58±4. 19％ for the two sterile lines separately.
