摘　　要：以13个北美大豆生育期组标准品种（MG0~MGⅢ）为对照,对东北及内蒙古地区不同生态区的25份大豆主推品种进行生育期组划分。结果表明：对照品种（MG0~MGⅢ）虽然生育日数存在差异,但在各年份均可正常成熟。参试品种（系）生育期组属MG0的最多,其次为MGⅢ、MGI、MGⅡ。由赤峰大豆综合试验站选育的优质高油、高产大豆品种赤豆1号和赤豆3号生育期组属MGI和MGⅡ。试验结果明确品种在赤峰地区的生育期组归属,为全国大豆生育期组系统的建立和不同区域新品种在各大豆产区的审定、繁殖和推广提供参考。Compared with 13 North America standard varieties （MGO - MG I11 ）, the growth periods of 25 varieties from different ecological areas in Northeastern China were studied. The results showed that although there were dif- ferences of growing period, all the controls could mature regularly in tested years. Most of tested varieties were subordinated to MG0, others were subordinated to MG m, MG I ,MG ]]. ＇Chidou 1＇ and ＇Chidou 3＇, bred by Chifeng Comprehensive Soybean Experimental Station, were subordinated to MG I and MG 11. The experiment made clear the growth period classification of soybean varieties in Chifeng, which provided the reference for not only validation, breeding and promotion in different regions, but also the establishing of soybean MG system and regionalize production regions in China.
