在甘肃中部沿黄灌区，选用22个大豆品种（系），在早熟马铃薯套作大豆的模式下，研究了各品种（系）主要农艺性状与产量之间的关系。相关性分析表明，大豆产量与主茎节数、有效分枝数、有效荚数和单株粒数呈极显著正相关。通径分析表明，单株粒数对产量贡献最大，其次是百粒重和有效荚数。通过聚类分析，供试材料可分为4个类群，选用域类最适宜。

The 22 soybean vareties(lines)was adopted to investigate the correlation between the main agronomic characters and yield under pototo intercropping soybean patterns in Gansu Irrigation Districts along Yellow River . The results indicated that the yield had significant correlation with the number of main stem,the number of efficient branch,the number of efficient pod,and the number of seed per plant . The path coefficient analysis showed that the number seed per plant contributed to yield mostly,then was 100-seed weight and the number efficient pod . Through cluster analysis,the results indicated that the materials could be classified into 4 groups, each group had its obvious features and theⅡgroup is suitable for early potato intercropping soybean condition .
