应用多元统计方法对黑龙江省审定的lO个高蛋白大豆品种的农艺性状与蛋白、产量之间的关系进行相关及通径分析。结果表明：高蛋白大豆品种的主茎节数、单株荚数、单株粒数、单株粒重与产量呈极显著正相关，茎粗与产量呈正相关，底荚高度与产量呈显著负相关，大豆蛋白含量和百粒重呈显著正相关。株高、主茎节数、单株粒重对产量的影响力最大。对于高蛋白大豆育种，应考虑选择株高中等偏高、主茎节数多、单株粒重大，同时百粒重较大、生育期为中晚熟的品种。

The correlation and path analysis among agronomic traits, protein and yield ol 10 hlgla protein soy- bean cultivars were examined by applying multivariate statistical analysis. The results indicated that： there were significantly positive correlations between node number of main stem, pods per plant, seed weight per plant and yield; stem diameter with yield. There was a significantly negative correlation between bottom pod height with yield, while protein content and 100-seed weight was significant positive correlated. The plant height, main stem and seed weight per plant had greater influence on yield. For breeding of high protein soy- bean the selection of medium high plant height, greater node number, grain weight per plant and 100-seed weight as well medium-late ripening variety should be considered.
