中文摘要: |
用4个稻瘟病菌小种对浙江省280份水稻新品种(系)进行稻瘟病抗性分析,结果表明:浙江省水稻新品种(系)对稻瘟病菌具有较好的抗性,籼稻和粳稻对参试菌株的全抗率分别为21.62%和39.05%,说明粳稻具有较籼稻更广的抗谱;浙江省新品种(系)对ZB13小种具有较高的感病率,籼稻和粳稻的感病率分别为69.37%和52.07%。 |
英文摘要: |
Four races of Magnaporthe grisea were used to evaluate the resistance of 280 new rice varieties(lines) from Zhejiang to rice blast.The results showed that the resistance of new rice varieties(lines) from Zhejiang to rice blast was high.The resistance ratio of indica rice to all races tested was 21.62% and that of japonica rice was 39.05%,which indicates that the resistance spectrum of japonica rice was broader than that of indica rice.The susceptibility ratio of new rice varieties(lines) from Zhejiang Province to ZB13 race was higher,and the susceptibility ratios for indica and japonica rice were 69.37% and 52.07%,respectively. |
