| 摘 要： | 利用"实践八号"育种卫星搭载"玉香油占"干种子,在褐飞虱爆发条件下,从M2代中首次获得农艺综合性状优良的抗褐飞虱水稻突变体PR955。遗传分析表明,PR955的抗褐飞虱性状受1对显性基因控制。米质检测分析表明,PR955的出糙率、精米率、整精米率均达国家一等优质米标准,综合评定为二等优质米。

| Abstract: | The dry seeds of rice variety Yuxiangyouzhan were carried by recoverable satellite shijian-8. Under the eruption of rice brown planthopper in Changsha in 2008, resistance-brown planthopper mutant PR955 was selected from M2 population on ground. PR955 had elite comprehensive agronomic traits. Genetic analysis and chi-square test showed that resistance character controlled by an dominance major gene. Indicated after the grain quality detection and analysis result that, PR955 reaches national high quality rice level of standards in brown rice rate, milled rice rate, as well as head milled rice rate. Its rice qualifies the second grade high-quality rice according to the high-quality rice standards of the Department of agriculture. |
