2005年全国热带亚热带春大豆品种区域试验

National spring-sowing soybean trial in tropical and subtropical regions in 2005

2005年全国春大豆热带、亚热带南方(北片)区域试验共有9个参试品种(系),对各参试大豆品种的产量、生育期及主要农艺性状的分析结果显示,粤春04-5产量最高,比浙春3号增产20.30%,达极显著水平;粤春04-6比浙春3号减产50.80%,比桂早1号减产72.88%,均达极显著水平;除粤春04-6生育期为117天外,其余8个大豆品种的生育期为104～107天.

National spring-sowing soybean trials in the south China＇s tropical and subtropical regions included 7 lines and 2 control varieties. This paper has analysed the yield performance, growth period and main agronomic traits of the lines. The result showed that Yue Spring 04-5 was highest in yield, increasing 20.30% as compared with CK1, reaching the remarkable level. Yue Spring 04-6 was 50.80% lower in yield than CK1, 72.88% than CK2, both reaching the extremely remarkable level. Except Yue spring 04-6, all lines could normally mature, with growth period ranging from 104 to 107 days. In addition, major agronomic traits such as plant height, branching number and pod number per plant were analysed.
