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、单株粒数呈显著或非显著的负相关 The main agronomic traits of 53 soybean cultivars promoted in the production areas of Huang-Huai-Hai and North China were analyzed and compared. The results showed that the major yield traits of the Huang-Huai-Hai region were significantly better than those of the northern region, but the cultivars of the northern region mostly prematurely mature. The soybean yield of the two regions in China was significantly higher , Grain yield per plant and some other yield traits and foreign varieties there is a clear gap. According to the correlation analysis of the two producing areas respectively, the number of branches, the number of main stems, the number of pods and the number of pods per plant were significantly or non-significantly positively correlated with the grain weight per plant and grain number ; The number of main stems had a significant positive correlation with the number of main stem pods and a significant or non-significant negative correlation with the weight of 100-kernels. There was a significant positive correlation between plant height, number of main stems, ; 100-grain weight had significant or non-significant negative correlation with the number of main stems, main stem pods, pods per plant and grain per plant
