本试验对山东省7个植棉地区的30个棉花枯萎病菌菌种标样进行了生理型鉴定。结果证明,这些菌种均属于生理型2号小种。又根据其对不同陆地棉品种的致病力差异,区分为四个致病类型,可供棉花抗病育种和品种合理布局参考。
In this experiment, 30 cotton Fusarium oxysporum strains were identified in seven cotton planting areas in Shandong Province. The results show that these species belong to Physiological 2 race. According to their differences in the pathogenicity of different upland cotton varieties, divided into four pathogenic types, for cotton disease-resistant breeding and variety reasonable layout reference.
