| 摘 要： | 用生物间遗传学关于毒力频率的方法,结合传统的鉴别寄主方法分析不同品种间稻瘟病菌群体的毒力差异。用于抗瘟性分析的菌株是2007年～2008年采集于黑龙江省17个县(市)、农场15个栽培品种共21份稻瘟病标样,共116株,在全国统一的7个鉴别品种上测试,共鉴定出7群20个中国生理小种,优势种群为ZA、ZD,总出现频率69.8%,优势小种为ZA49、ZD5,总出现频率37.9%。将其中的48株生理小种分别接种到供试的15份材料上,结果表明:同一生理小种的不同菌株在鉴别品种外供试材料上的反应差异较大,不同优势小种对同一品种致病力反应差异也较大;毒力频率低于30%品种有垦稻12、龙粳26号,是抗性较好的品种。 |

| Abstract: | The pathogenic frequency differences among blast pathogen populations were analyzed by pathogenic frequency in biological genetics and through conventional host identification method,and the results showed that among 116 strains in 21 races obtained from 15 cultivated rice varieties in Heilongjiang in 2007 and 2008,20 strains in seven races identified in seven test rice varieties were found.The dominant populations were ZA and ZD with a frequency 69.8% and the dominant races were ZA49 and ZD5 with a frequen... |
