摘　　要：为明确黑龙江省不同生态区近30年大豆育成品种主要育种性状的选择目标，利用相关系数、主成分分析方法对育种性状进行了分析。结果表明：第1生态区可同时选择株高与蛋白质含量，第2生态区可同时选择百粒重、蛋白质含量和产量，第3生态区可同时选择株高与百粒重，第4、6和9生态区可同时选择脂肪含量与产量，第8生态区可同时选择百粒重与蛋白质含量，第10生态区可同时选择株高与脂肪含量，第11生态区可同时选择蛋白质含量和产量。在主成分分析中，选取累计贡献率为80．12％-90．77％的前3个主成分来评价黑龙江省大豆品种资源。All soybean cultivars released in the past 30 years from different ecological regions in Heilongjiang province were analyzed by correlation coefficient and principal component analysis for traits selection. The results showed that it was feasible to select plant height and protein content simultaneously in the first ecological region, 100-seed weight, protein content and yield in the second ecological region, plant height and 100-seed weight in the third ecological region, fat content and yield in the fourth,the sixth and the ninth ecological region, 100-seed weight and protein content in the eighth ecological region, plant height and fat content in the tenth ecological region, protein content and yield in the eleventh ecological region. Then first three principal components whose accumulative contribution rate varied from 80.12% to 90.77% were selected to evaluate soybean resource in Heilongjiang province.
