| 摘要: |
| 以药用野生稻1665(O.officinals)和栽培稻桂99远缘杂交的抗褐飞虱近等基因系B3F4分离群体为材料,利用随机引物对其抗褐飞虱基因进行了RAPD标记研究,获得3个与抗褐飞虱基因表现连锁的RAPD分子标记(S229703、S403783和S11591408)。采用MAPMAKER/EXP.Version 3.0分析,结果表明3个RAPD分子标记与抗褐飞虱基因属于同一连锁群,覆盖大小为18.1 cm,标记间平均距离为4.53 cm,为下一步水稻抗褐飞虱基因的精确定位和克隆奠定坚实的基础。 |

| Abstract: |
| B3F4,a near-isogenic line(NIL)with Bph,was screened by distant hybridization of Oryza officinals 1665 and Oryza sativa Gui99,three molecular markers,S229703,S403783 and S11591408,linked to Bph,were obtained through RAPD analysis of B3F4 with random primers. The result of MAPMAKER/EXP. Version 3.0 analysis showed that these three molecular markers were belonged to the same linkage group with Bph,the covered range was 18.1cM and the average distance between markers was 4.53cM. This result will facillitate the futher accurate localization and cloning the Bph gene. |
