| 摘 要： | 选用254份黄淮麦区小麦品种(系),利用BFMR1,DFMR2和微卫星xgwm261标记检测了矮秆基因Rht-B1b,Rht-D1b和Rht8的分布.结果表明,在254份材料中,含有Rht-B1b,Rht-D1b和Rht8基因的材料分别有84,171和178份,平均株高分别为80.7,78.5和80.7 cm.只含有Rht-B1b,Rht-D1b和Rht8基因的材料分别有15,36和31份,平均株高分别为83.8,80.1和86.2 cm.只含Rht-B1b和Rht-D1b基因有16份,平均株高为73.7cm,Rht-B1b和Rht-D1b基因具有累加效应,两个基因同时存在时株高降低幅度会更大.只含Rht-B1b和Rht8基因的有94份,只含Rht-D1b和Rht8基因的有28份,同时含有Rht-B1b,Rht-D1b和Rht8基因的有25份,同时不含这3个矮秆基因的有9份,说明黄淮麦区小麦品种(系)中绝大部分品种均含有不同种类的矮秆基因.微卫星WMS 261及基于PCR的2个STS标记可以分别用于对品种(系)中Rht8,Rht-B1b和Rht-D1b基因型的鉴定以及育种世代该基因型的筛选.

| Abstract: | The distribution of Rht-B1b,Rht-D1b and Rht8 for 254 wheat lines from Huang-huai wheat area was studied by means of molecular markers BFMR1, DFMR2 and Xgwm261.The results showed that 84,171 and 178 lines were found to take Rht-B1b,Rht-D1b and Rht8 gene respectively,and that the corresponding average height was 80.7,78.5 and 80.7 cm respectively.The number of lines only with Rht-B1b,Rht-D1b and Rht8 was 15,36 and 31 respectively,and the corresponding average height was 83.8,80.1and 86.2 cm respectively.Sixte... |
