大豆蚜虫抗性鉴定技术及抗性资源筛选

Identification Techniques and Screening of Soybean Aphid Resistant Germplasm

探讨人工气候箱和田间网室2种接蚜鉴定方法对大豆蚜虫的鉴定效果,并用田间网室鉴定方法对109份黑龙江省栽培大豆进行蚜虫抗性分析。结果表明:田间网室和人工气候箱均能准确鉴定大豆品种的抗性;所有鉴定品种间抗性差异明显,但是没有免疫和高抗品种,抗性材料37份,占总检测材料的33.9%。

The soybean aphid has recently become a principal pest of soybean in many areas.Selecting resistance cultivars is the most practical and effective means of pest control.In this paper we implemented the growth-chamber and field cage screening method respectively,and found the field cage screening method had same effect as growth-chamber screening method.One hundred and nine soybean cultivars from Heilongjiang province were evaluated in field cage,and 37 accessions were found to resistant to the soybean aphid and no strong resistance germplasm was found.
