江汉平原早熟大豆新品种适应性研究

Research on the Adaptability of New Early Maturing Soybean Varieties in Jianghan Plain

引进18个近年新育成的早熟大豆(Glycine max)品种在江汉平原进行了适应性试验。结果表明,鄂2074不倒伏,产量最高,适应性最强;油春14-3和油春16-332产量高,轻度倒伏;鄂2077产量较高,不倒伏,适应性较好;油春316、油春337和油春15-3产量高,倒伏较重;贡827、油春11-1和油春327产量表现一般,轻度倒伏或不倒伏,均不推荐种植;中豆40和鄂2066产量中等,倒伏严重;油春314、油春11-6-1、衡春9451、湘春豆26、天隆1号和油春14-1等品种产量表现较差,均不宜在江汉平原种植。

Adaptability of 18 new early maturing soybean varieties was studied. The results showed that E 2074 had the strongest adaptability,with no lodging and the highest yield. Youchun 14-3, Youchun 16-332 and E 2077 had stronger adaptability. Youchun 14-3 and Youchun 16-332 had negligible lodging and better yield, and E2077 had higher yield with- out lodging. You chun 316, You chun 337 and You chun 15-3 had more serious lodging and high yield. Gong 827, You chun 11-1 and You chun 327 had no lodging or negligible lodging and average yield, so they could not be recommended for planting. Zhongdou 40 and E 2006 had medium-yield and serious lodging, and other varieties such as You chun 314, You chun 11-6-1, Heng chun 9451, Xiang chundou 26, Tianjiangyihao and You chun 14-1 had poor yield. They are not suitable for planting in this area.
