| 摘 要： | 本文描述了河南省发生日趋严重的花生网斑病在田间出现的一种新的病斑类型,并结合已报道的两种病斑类型,对3种病斑类型的病原菌开展致病力差异研究。研究结果表明:田间新发现的花生网斑病病斑特征明显,综合分析后将花生网斑病病斑类型分别定为网纹型、类褐斑型和污斑型;同一花生品种上3种病斑类型病原菌菌株间存在明显的致病力差异,同一病斑类型菌株对不同花生品种的致病力也表现出显著差异。

| Abstract: | A new lesion type of peanut web blotch caused by Peyronellaea arachidicola was described and the virulence differences of the pathogens resulting in different lesion types were investigated in this research. By a comprehensive analysis of the lesion features, three lesion types of peanut web blotch were sorted, including type of reticulate elongation, type of brown spot like and type of irregular stain. Furthermore, virulence test showed that virulence was significantly different not only among pathogens caused three lesion types on the same peanut cultivar, but also among the peanut cultivars caused by same pathogen with the same lesion type. |
