东北黑土区中部海伦地区大豆品种生育期组归属研究

The Study on the Maturity Group of Soybean Varieties in Hailun in the Centre of Black Soil Region in Northeast China

为了实现大豆不同栽培区域间的科学引种,以13个分属于MG(maturity group)000-I的北美大豆生育期标准品种的生育期表现为参考,在海伦试验站,通过4年的对比试验,对14份的东北黑土区中部海伦市的主栽品种和新近选育品种的生育期组进行鉴定和划分。结果表明:除了PI548596在2011年未能正常成熟以外,其余12个北美标准品种和所有的13个北美标准品种在2011-2014年均能够正常成熟。参试的14份大豆品种的生育期组介于MG00-MGI之间,其中主栽品种和新选育的品种有84%属于MGI组,而国家及省级区域试验对照品种绥农14在2011和2013年属于MG0组,而在2012和2014年则属于MGI组。

To promote the scientific introduction of soybean varieties among different cultivation regions in China, 14 soybean varieties including the major varieties and new varieties of Hailun city were compared with 13 MG standard varieties of North America including MG000-MGI maturity groups.The results showed that all standard varieties could mature in Hailun station in autum from 2011-2014 with exception of PI548596 in 2011, indicating that selected reference varieties were suitable for the climatic conditions in Hailun city. The tested 14 varieties from Hailun belong to MG00-MGI maturity groups, and 84%of major and new varieties belong to MGI maturity group.However, the control variety of Chinese national and province experiments, Suinong 14, belonged to MG0 in 2011 and 2013, but to MGI in 2012 and 2014.
