Abstract?The test was arranged by the intercomparison method, comparative test was conducted on 33 new summer soybean varieties (lines) in Henan Province. Results showed that a total of 18 varieties of Yongpengdou 6, Shangdou, Zhoudou 46, Zhudou 35, Yuyandou 086, Sudou 13, Zhongdou 6301, Sudou 8, Guodou 2, Xudou 11, Wufengdou 8, Yufengdou 369, Huayu 11, Shengyu 10, Zhonghuang 321, Weidou 22, Kedou 29, Daoqiu 23 showed 5% higher yield than Zheng 196 (CK). The yield increase ranged from 6.21% to 59.74%;plant height was 728-104.0 ?cm. The height of the bottom pod was 8.6-16.6 ?cm,mostly higher than Zheng 196 (CK), which was suitable for machine collection;the number of main stem nodes was 11.4-18.4,effective branches ranged from 0.6 to 3.6,compared with Zheng 196 (CK), both were moderate;the grain weight per plant was 23.3-34.3 g,100grain weight was 19.0-27.6 g,the number of grains per plant was between 81.6 and 180.4;the effective pod number per plant was 38.6-91.8. These 18 varieties showed better performance compared with Zheng 196 (CK). Growth period was between 109 and 113 d, none of which exceeded Zheng 196 (CK). Therefore, these 18 varieties were suitable for subsequent trials.

大豆是中國重要糧食作物之一,已有5 000年栽培歷史[1],而且大豆含有豐富植物蛋白質,是重要的食用植物油和飼料蛋白來源。隨著農業供給側結構的改革,大豆在農業生產中占有重要地位,2017年全國大豆播種面積超過0.08億hm2[2],大豆面積的增加不僅提升了國產大豆供給水平,也為有效應對國內外復雜環境和風險挑戰提供了基石。
河南是黃淮海大豆產區的重要省份,大豆常年種植面積達46.67萬hm2[3],但平均單產長期在22 500 ?kg/hm2左右。而大豆是優化調整種植結構的主要作物,因此推出一批高產優質、效益較高的大豆品種是大豆產業發展的關鍵[4]。為了發揮農業科研單位的優勢,推進河南大豆產業可持續發展,2019年新鄉市農業科學院承擔了河南省夏大豆新品種(系)比較試驗,筆者研究了河南省供試大豆新品種(系)的農藝性狀和產量,篩選出高產、穩產、適應性強、綜合性狀優良、適合大面積機械化種植的大豆新品種,旨在為新品種審定和推廣提供科學依據[5-11]。
