不同花生品种对花生果腐病的抗性鉴定

采用自然病圃鉴定法，对76个花生品种（系）进行了花生果腐病抗性评价，以期为抗病育种及田间病害防治提供理论依据和抗性材料。结果表明，不同花生品种间对花生果腐病的抗性存在着显著差异，供试76份花生品种（系）中未发现对果腐病免疫的品种，获得高抗品种2个，抗病品种7个，中抗品种12个，感病品种21个，高感品种33个。聚类分析结果表明，分支I中的9个品种（尤其是花育9115）抗性较好，可进一步加以利用。花生对果腐病的抗感性与荚果鲜重之间不存在显著相关。

Evaluation of resistance of different peanut varieties to peanut pod rot

he resistance evaluation to peanut pod rot of 76 peanut varieties（lines）was carried out in naturaldisease field, with the aim to provide theoretical basis for disease resistance breeding and field disease control. Theresults showed that there were significant differences in the resistance of different peanut varieties to peanut pod rot.Among the 76 peanut varieties tested, there were no immune varieties to peanut pod rot, 2 high resistant varieties, 7resistant varieties, 12 medium resistant varieties, 21 susceptible varieties and 33 high susceptible varieties. The re⁃sults of cluster analysis showed that the resistance of 9 species in branch I（especially Huanyu 9115）was desirableand could be further utilized. The correlation between peanut resistance to pod rot and pod fresh weight was ana⁃lyzed and no correlation was found.
