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 clarify the division of main growing soybean groups in Huaibei area of Anhui Province and facilitate the introduction of different regions of soybean, reference was made to the growth stages of 13 North American soybean standard varieties (MG) (maturity group) Ⅱ-MG Ⅴ in 2012 and 2013, Through two years of comparative experiments, 22 main cultivars in Huaibei area of Anhui province and the newly growing varieties in recent years were divided into two groups. The results showed that 13 North American standard cultivars could mature normally in Suzhou, and 22 test cultivars had the same growth period between MGⅡ-MGⅤ. Among them, one in MGⅡgroup and one in MGⅣ-MGⅤ group, accounting for 4.5% of the tested varieties; MGⅢgroup and MGⅢ-MGⅣgroup each had 8 varieties, The number of 36.4% ;; MGⅣ group of 4, accounting for 18.1% of the number of varieties tested. Based on the results of two years’ experiment, main cultivars in Huaibei area of Anhui Province are mainly concentrated in two growth stages of MGⅢ and MGⅣ.
