不同花生品种对花生褐斑病的抗性评价

Evaluation of Resistance of Different Peanut Varieties to Peanut Brown Spot

采用自然病圃检测法,分别对34种花生品种(系)进行了花生褐斑病抗性评价,以期为抗病育种及田间病害防治提供理论依据。研究结果表明,不同花生品种间对花生褐斑病的抗性存在着显著差异,供试34个花生品种中没有对褐斑病免疫的品种,高抗品种3个,中抗品种9个,抗病品种11个,感病品种8个,高感品种3个。聚类分析结果表明,翼9801等6个品种抗性较好,可进一步加以利用。

In this study, 34 peanut varieties were evaluated for their resistance to brown spot disease by natu- ral bed test, in order to provide theoretical basis for resistance bleeding and field Disease control. The results showed that peanut brown spot disease was diffm^nt between different peanut varieties. The following conclu-sions showed ： there were no immune against brown spot disease in 34 peanut varieties, 3 high resistance varieties,9 resistant varieties, 11 resistant varieties, 9 susceptible varieties and 3 sensitive varieties. The results of cluster analysis showed that 6 varieties had good resistance and could be used further.
