摘 要： 福建省清流县种子管理站承担国家热带亚热带地区夏大豆品种区域试验，引进7个热带亚热带地区夏大豆品种进行区域试验。结果表明：华夏2号早熟，抗倒伏性较好，平均产量为3 343.5  kg·hm-2  ，比对照品种华夏9号、华夏2号分别增产21.01%、27.30%，且达极显著水平;桂夏7号熟期适中抗倒性较好，平均产量为2 844.0  kg·hm-2  ，比对照品种华夏9号、华夏3号分别增产2.91%、8.26%，增产未达显著水平;华夏14号早熟，抗倒伏性好，平均产量为2 806.5  kg·hm-2  ，比对照品种华夏9号、华夏3号分别增产1.59%、6.86%，增产未达显著水平。综合各品种生育期、产量、商品性（籽粒大小）、株高等特征特性考察，建议桂夏7号进入生产试验，华夏2号、华夏14号等2个品种继续参加区域试验;桂1306、桂夏豆109等2个品种终止试验。

Abstract：  Qingliu Seed Management Station in Fujian Province undertook a regional test of summer soybean varieties at tropical and subtropical area in China， in which seven summer soybean varieties from tropical and subtropical area were introduced and compared. The results showed that ‘Huaxia No.2 had characteristics of early maturity， high lodging resistance and average yield of 3 343.5  kg·hm-2  ， which was very significantly higher than the control ‘Huaxia No.9 and ‘Huaxia No.2 by 21.01% and 27.30%， respectively. ‘Guixia No.7 had characteristics of moderate maturity period and high lodging resistance and averaged yield of   2 844.0  kg·hm-2  ， which was higher than that of the control ‘Huaxia No.9 and ‘Huaxia No.3 by 2.91% and 8.26%， respectively without significant level. ‘Huaxia No.14 had characteristics of early maturity and good lodging resistance. The average yield of ‘Huaxia No.14 was of 2 806.5  kg·hm-2  ， which was higher than the control ‘Huaxia No.9 and ‘Huaxia No.3 by 1.59% and 6.86%， respectively without significant level. By comprehensive analysis of their growth period， yield， commodity character （grain size） and plant height， so we suggested that ‘Guixia No.7 could be used in production experiment; ‘Huaxia No.2 and ‘Huaxia No.14 should continue to be in regional test and the test of ‘Gui 1306 and ‘Guixiadou 109 should be halt.

清流縣位于福建省西北部，属亚热带季风气候，全年无露期245～278 d，年平均气温19.6℃，年平均日照时数1 877.7  h，年降水量1 600～ 1 800  mm[1-2] 。福建是大豆极缺省份，由于大豆育种力量薄弱，生产应用的夏大豆品种少，主要以春大豆品种倒种为主。为筛选适合福建省种植的高产、优质、成熟期适中的大豆新品种，为科学、公正、及时地审定大豆品种提供依据，满足福建省对高产大豆品种的种植需求，清流县种子管理站承担了2017年国家热带亚热带地区夏大豆品种区域试验。现将试验结果报道如下。

1 材料与方法

1.1 供试材料

供试大豆品种共7个，其中桂夏豆109、桂夏7号、桂1306、华夏2号、华夏14号、华夏9号（CK 1，作为中熟品种对照）、华夏3号（CK 2，作为迟熟品种对照）由华南农业大学选育。……
