安徽淮北地区主栽大豆品种生育期组划分的研究初报

A Preliminary Study on Maturity Group Classification of Soybean Cultivars in Huaibei of Anhui

为了明确安徽淮北地区主栽大豆品种生育期组的划分,方便大豆不同地区之间的引种,于2012、2013年以13份北美大豆标准品种MG(maturity group)Ⅱ-MGⅤ生育期组为参照,通过2年对比试验,对安徽淮北地区22份主栽品种和最近几年新育成品种的生育期组进行划分。结果表明,13个北美标准品种在宿州均能正常成熟,22份试验品种的生育期组介于MGⅡ-MGⅤ。其中,在MGⅡ组和介于MGⅣ-MGⅤ组的品种各有1个,均占参试品种数的4.5%;MGⅢ组和介于MGⅢ-MGⅣ组的品种各有8个,均占参试品种数的36.4%;;MGⅣ组有4个,占参试品种数的18.1%。综合2年的试验结果,安徽淮北地区的主栽品种主要集中在MGⅢ和MGⅣ两个生育期组内。

In order to promote introduction between different regions and clear to know soybean varieties classifi- cation in area of Huaibei. We identified the MG （ maturity group） categories for 22 main cuhivars with 13 MG standard varieties from North America, which covered MG Ⅱ-MG Ⅴ in this study. The results showsed that the 13 MG standard varieties and 22 main cultivars could mature in 2 years. 1 soybean cuhivars belonged to MG Ⅱ and MGIV-MG Ⅴ , respectively, account for 4.5 %. 8 soybean cultivars belonged to MG m and MG m-MG IV, respec- tively, account for 36.4%. 4 soybean cuhivars belonged to MGIV, account for 18.1%. Comprehensive 2 years re- suits demonstrated that the main cuhivars belonged to MG Ⅱ-MG Ⅴ in Huaibei of Anhui.
