| 本文旨在揭示元江普通野生稻渗入系白叶枯病抗性与粳籼分化的关联性。利用SSR标记从分子角度分析280份云南元江普通野生稻渗入系的粳籼类型,并采用人工剑叶接种方法鉴定渗入系对中国标准白叶枯病菌(C4-C9)的抗性,通过SPSS软件分析渗入系不同粳籼分化类型对白叶枯病抗性的影响。280份渗入系出现了明显的粳籼分化,对供试菌株的抗性良好,抗谱多样化。在所有参试材料中,相对于粳型材料,籼型抗性材料所占比例多,平均病斑长度短,抗谱也较广。元江普通野生稻中的广谱高抗白叶枯病基因主要渗入到籼稻中,广谱高抗白叶枯病抗性基因来源于籼型材料可能性较大,推测水稻白叶枯病基因可能起源于籼稻。 |

| This paper aims to reveal the connection between bacterial blight resistance and japonica-indica differentiation of Yuanjiang common wild rice introgression lines. The japonica-indica type of 280 Yunnan Yuanjiang common wild rice introgression lines was analyzed by using SSR marker on the molecular point of view, and the introgression lines were inoculated with six races (C4-C9) of Xanthomonas oryzae pv. oryzae (XOO), in order to assess the resistance of the introgression lines to bacterial leaf blight. SPSS software was used to analyze the difference of resistance to bacterial leaf blight among different indica-japonica differentiation type in introgression lines. There were obvious indica-japonica differentiation in the 280 introgression lines, which showed good resistance to the tested strains and diversity of resistance spectrum. In all the materials tested, compared with japonica rice, indica resistant material accounted for more proportion, the average lesion length was short, the resistance spectrum was broader. It is possible that the broad-spectrum resistance to bacterial blight is derived from indica rice, suggesting that the rice bacterial blight gene may originate from indica rice. |
