超级早稻中早39稻瘟病抗性的系谱分析
Genealogical Analysis on Resistance to Magnaporthe oryzae of Super Early Rice Zhongzao 39
摘要
Abstract
[Objective]To clarify the genetic basis of the durable resistance to Magnaporthe oryzae of the super early rice Zhongzao 39,[Method]blast resistance assessment, molecular marker screening and gene sequencing were conducted.[Result]Zhongzao 39, Jinzao 47 and Zhongzu 3 showed positive bands to all the molecular markers for 7 resistant genes Piz, Pi9, Pib, Pi36, Pi64, Pi-d2 and Pi-d3; The resistance performance of Zhongzao 39, were fully consistent with Jinzao 47 and Zhongzu 3 to the 5 isolates collected from Zhejiang and Jiangxi Province, China; Molecular sequencing results showed that all the test materials contain Pi-d2 resistant alleles. [Conclusion]These results showed that the genetic basis of durable resistance to Magnaporthe oryzae of Zhongzao 39 was contributed by Jinzao 47 and Zhongzu 3.关键词
