摘要
对我国黄淮海产区和北方产区生产上推广的 5 3个大豆品种的主要农艺性状进行了分析比较。结果表明 ,黄淮海产区品种的主要产量性状都明显优于北方产区的品种 ,但北方产区品种大都偏早成熟 ;我国上述 2个产区大豆品种在单株荚数、单株粒重、单株粒数等一些产量性状上与国外品种存在着明显的差距。就 2个产区材料分别所作的相关分析指出 ,大豆分枝数、主茎荚数、分枝荚数、单株荚数均与单株粒重和粒数呈显著或非显著的正向相关 ;主茎节数与主茎荚数呈显著正相关 ,与百粒重呈显著或非显著的负向相关 ;株高与主茎节数、单株粒数与单株粒重正相关极显著 ;百粒重与主茎节数、主茎荚数、单株荚数。
The comparison amongst agronomic traits of fifty-three varieties of soybean, which were from the growing-areas of Huanghuaihai and northern China for the study, showed that most of the yield component of varieties from Huanghuaihai areas were superior to that of those from north China. But most of the latter were with earlier maturity. There were remarkable differences between the China-developed varieties and the exotic in some main yield component, such as pods per plant, seed weight per plant, seed number per plant — the former materials were generally with lower numerical values. The correlation analyses ,by using all above materials, indicated that significantly positive or non-significantly positive relations existed between branch number, pods in main stem, pods in branches, pods per plant and seed weight or seed number per plant. There was a striking positive relativity between node number and pod number in main stem while that between the node number and 100-seed weight was negative. Between plant height and main stem nodes, seed number and seed weight per plant was significant positive; whereas negative between 100-seed weight and nods and pods of main stem, pods and seeds per plant.
