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。
The resistance evaluation of 336 soybean materials from 20 countries including China, Russia, Canada, Hungary, Austria, Germany, France, Poland and so on was evaluated. Fifty-eight high resistant materials, 64 resistant materials, Insect material accounted for 34.7%, mainly from China and Russia. Insect resistance of soybean cultivars and soybean cultivars were analyzed and the results showed that the insect resistances of soybean cultivars were similar to those of the soybean cultivars with the same number of pests, the number of seeds per plant, the weight per plant, Heavy, pod hair density, the color of the seed coat was significantly related to soybean plant short, small seeds, pods less pods, seed coat black soybean varieties better resistance.
