通过 1 8个菌株对 2 3个不同抗、感品种的棉花苗期接种试验 ,及 1 0个菌株对 9个苏棉 1 2号R和 1个南农 1号耐黄萎病株行的苗期和吐絮期病指相关分析 ,明确了要培育出能在大多数病区都表现抗病的棉花品种 ,应以V2 5、XS4这样的强致病力菌株作为病圃鉴定菌株。棉花抗黄萎病育种目标应以抗强致病力或落叶型菌系为主
A total of 28 strains of cotton seedlings were inoculated with 23 different resistant and susceptible cultivars, and 10 seedlings of 9 Sumian 12 R and 1 Nannong 1 resistant to Verticillium dahliae Period and bollworm disease related analysis, it is clear that we should cultivate cotton varieties that can show disease resistance in most wards. Virulent virulent strains such as V2 5 and XS4 should be used as pathogen identification strains. Resistance to Verticillium wilt breeding objectives should be resistant to strong virulence or deciduous strains
