摘　　要：对来自中国、俄罗斯、加拿大、匈牙利、奥地利、德国、法国、波兰等20个国家的336份大豆材料进行大豆食心虫的抗性评价,鉴定筛选出高抗材料58份,抗性材料64份,抗虫材料占34.7%,主要来自中国和俄罗斯。大豆品种抗虫性与大豆品种农业性状进行相关分析,及不同地理生态区大豆资源的抗虫性结果表明:大豆品种抗虫性与与节数、单株粒数、单株粒重、百粒重、豆荚茸毛密度、种皮颜色呈显著相关,大豆植株矮小,籽粒小、豆荚荚毛少,种皮黑色的大豆品种抗虫性较好。336 soybean cultivars from China, Russia, Canada, Hungary, Austria, Germany, France, Poland and other 20 countries were estimated with the resistance to soybean pod borer and 58 eultivars were found to be highly resistant to soybean pod borer and 64 euhivars with satisfied resistance were screened, accounting 34. 7%. The relationships were studied between soybean pod borer resistance and agricultural characters. The results showed there is significant eorrelationship between nods number in main stem, pods number per plant, seeds per plant, seed weight per plant, weight of 100 seeds, pnbes-cenee den- sities, color of seed coat and soybean pod borer resistance. The conclusion was that the soybeans, which hadless nods in main stem, small seeds, non-lodging, low density of pubescence, black color of seed coat possessed poor egg deposition and less damage from soybean pod borer.
