国家热带亚热带地区夏大豆品种区域试验

    Regional Test of Summer Soybean Varieties in Tropical and Subtropical Area China

    • 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.
