不同花生品种(系)对花生网斑病的抗性评价

Evaluation of Resistance of Different Peanut Varieties to Peanut Net Blotch

[目的]为花生品种示范推广提供理论依据。[方法]采用室内离体喷雾接种法和田间抗鉴圃自然感染诱发法,分别对37个花生品种(系)进行了花生网斑病抗性评价。[结果]室内离体接种法和田间抗鉴圃自然感染诱发法结果基本一致,不同花生品种(系)间对花生网斑病的抗性存在显著差异。[结论]供试37个花生品种中,抗病品种4个,中抗品种22个,感病品种7个,高感品种4个,未发现免疫和高抗品种。

[Objective]To provide theoretical basis for the demonstration and promotion of peanut varieties.[Method]The indoor in vitro spray inoculation method and the field natural infection induction method were used to evaluate the resistance of net spot of peanut to 37 peanut varieties(strains).[Result]The results of indoor in vitro spray inoculation method and the field natural infection induction method were basically the same.There were significant differences in resistance to peanut net spot among different peanut varieties(strains).[Conclusion]In this study 37 varieties of peanut were tested,4 varieties were disease resistant,22 varieties were medium resistance,7 varieties were disease-sensitive,4 varieties were high-sensitive,immune varieties and high-resistance varieties were not found.
