航天诱变水稻抗褐飞虱新种质的培育、遗传分析与生物学特性
Development of a Novel Rice Germplasm in Resistant Brown Planthopper from Space-induced Rice Mutants and Analysis of Its Genetic Traits and Biological Characteristics
摘要
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.关键词
