摘要：

在观察筛豆龟蝽发生情况及其在大豆上的危害特征基础上,比较了田间自然危害条件下各种抗性鉴定指标，以茎枝黑霉程度结合叶片紫斑数为抗性分级指标鉴定了国内外大批资源，筛选出58份抗、感食叶性害虫的大豆材料，其筛豆龟蝽抗性结果表明，品种间、观察日期间和区组间都有极显著差异，品种×观察日期互作也极显著，最终筛选出PI227687、安陆小黄豆、花柒黄毛豆、沔阳白毛豆等高抗种质，并提出了一套鉴定方法和指标。

Abstract:

Globular stink bug [GSB, Megacota cribraria (Fabricius)] is reported as one of the often-happened insects, and sometimes, soybean plants are seriously damaged in the production in central and southern China. The objective of the present study was to establish an evaluation system of resistance to the insect and to identify resistant sources for breeding purposes. Based on the observation of occurrence and symptoms of the insect on soybeans, a set of resistance (damage) indices were designed and compared. Among them, the grade system according to the degree of black mildew on stem and purple spots on leaves was chosen to evaluate the resistance to GSB of 58 entries screened from 6724 domestic and foreign germplasm accessions. The results showed that there existed significant difference among accessions, observation dates, blocks, and accession×date. A group of highly resistant accessions, such as PI227687, Anluxiaohuangdou, Huaqihuangmaodou, Mianyangbaimaodou, were screened for breeding purposes. At the same time, a set of identification procedure and grading system were proposed for further study.
