以38个分属MG000~MGVIII的北美大豆生育期组标准品种的生育期表现为参考,通过多点对比试验,对来自16个试验组的国家大豆品种区域试验19个对照品种进行生育期组鉴定与划分。所有品种均在北京、武汉两地春播,并选用部分代表性品种在18个国家大豆品种区域试验点进行补充试验。结果表明,国家大豆品种区域试验对照品种的生育期组介于MG0~MGVI之间。不同区域的对照品种可归属相同的生育期组。北方春大豆区晚熟组、西北春大豆区、黄淮海夏大豆区及西南山区春大豆区的对照品种均属MGIII;长江流域春大豆区、热带亚热带夏大豆区对照品种属MGV或MGVI。热带亚热带春大豆区2个对照品种福豆301和泉豆7号所在生育期组差异较大,分别归属MGII和MGIV。根据生育期组并考虑其他因素,建议将黄淮海夏大豆品种区域试验组由目前3个组以黄河为界划分为2个组,并对南方部分试验组进行调整。北方春大豆晚熟组和西北春大豆区对照品种尽管生育期组相当,但因品种抗旱性要求不同,建议分别设置区域试验。 Based on the growth performance of 38 North American soybean growth stage standard varieties belonging to MG000 ~ MGVIII, 19 control varieties from the national soybean variety regional test from 16 experimental groups were identified by multi-point comparison test. With the division. All cultivars were sowed in spring in Beijing and Wuhan, and some representative varieties were selected for supplementary testing in regional soybean test sites in 18 countries. The results showed that the national soybean varieties regional test control varieties of the growth period between the MG0 ~ MGVI. Control breeds in different regions can belong to the same fertility group. The control varieties of late spring in northern spring soybean group, northwest spring soybean region, Huang-Huai-Hai summer soybean region and southwest mountainous spring soybean region belong to MGIII. The control varieties of spring soybean zone and tropical summer soybean zone in the Yangtze River Basin are MGV or MGVI. The tropical subtropical spring soybean area two varieties Fukuda 301 and Spring bean 7 where the growth period group differences are attributed to MGII and MGIV respectively. According to the growth period group and considering other factors, it is suggested that the regional experimental group of Huanghuaihai summer soybean varieties be divided into two groups from the current three groups with the Yellow River as the boundary, and some southern southern experimental groups will be adjusted. The northern spring soybean late-maturing group and the northwest spring soybean area control varieties despite the same growth period group, but the drought resistance requirements of different varieties, it is recommended to set the regional test.
