大豆品种抗病虫性评价及多抗性抗源筛选

Identification of Diseases and Insect Pests Resistance and Screening of Multi-Resistance Sources of Soybean Varieties

通过人工接菌和田间自然鉴定的方法,对大豆食心虫、大豆蚜和大豆菌核病进行了品种抗性鉴定。从92个品种和品系中,鉴定出高抗大豆食心虫6个,抗16个,中抗36个,感虫34个。从112个品种(系)中,鉴定出高抗大豆菌核病1个,抗12个,中抗17个,感57个,高感25个。从34个初选品种(系)中,鉴定出中抗大豆蚜12个,感22个。综合选出抗2虫1病、抗倒伏及高产的多抗品种6个。

Using artificial inoculation and field identification, resistance of soybean varieties to soybean pod borer, soybean aphid and Sclerotinia stem rot was identified. Among 92 varieties, 6 HR, 16 R, 36 MR and 34 S were identified to resist soybean pod borer. Among 112 varieties, 1 HR, 12 R, 17 MR, 57 S and 25 HS were identified to resist Sclerotinia stem rot. Among 34 varieties, 12 MR and 22 S were identified to resist soybean aphid. 6 multi-resistant high-yield soybean varieties resisting 2 insect pests, 1 disease and lodging were comprehensively screened.
