黑龙江省主要大豆品种生育期组归属研究

以12份分属MG0-MGⅢ的北美大豆生育期组标准对照品种在黑龙江省三江平原地区的生育期表现作为参考依据,分别于2012、2013年对黑龙江省大豆区域试验对照品种和主栽品种进行生育期组归属划分,以明确该区域大豆主要品种的生产适应范围。结果表明,2012-2013年北美大豆标准生育期对照品种组间生育日数呈不断递增趋势,界限清晰,数据可用于生育期组划分参考,归属品种各生育阶段生育日数与标准品种差异显著。综合两年试验结果,确定归属于MG0组的大豆品种有华疆2号、黑河38、黑河43和黑河45,归属于MGⅠ组的大豆品种有合丰51、合丰50、合丰55、绥农26、绥农28和黑农44,归属于MGⅡ组的大豆品种有黑农51和垦丰16。

Classification on maturity groups of main soybean cultivars in Heilongjiang

12 MG standard varieties of MG0～MGⅢ from north USA sown in Sanjiang plateau of Heilongjiang were used as reference to identify the MG categories for local popular varieties in Heilongjiang in 2012 and 2013. The results showed that the maturity group’s growth period of the north USA standard varieties presented constant increase trend, and the borders were obvious that can be used for maturity group classification. There were significant differences in different growth period between group varieties and standard varieties. Results from 2 years showed that Huajiang 2, Heihe 38, Heihe 43 and Heihe 45 belonged to MG0 group; Hefeng 51, Hefeng 50, Hefeng 55, Suinong 26, Suinong 28 and Heinong 44 belonged to MGⅠgroup; the varieties of Kenfeng 16 and Heinong 51 belong to MGⅡ group.
