摘　　要：应用灰关联分析法对河南安阳市农业科学院2011年大豆区域试验当中的15个品种的农艺性状与单株产量之间的关系进行灰关联分析。结果表明,各农艺性状对单株产量的影响,以单株荚数最大,其次为单株粒数、分枝数,百粒质量和株高对单株产量影响则较小,节数影响最小。在安阳市生态条件下,大豆高产育种的策略应确定为:在稳定粒数和百粒质量的基础上,侧重选择单株荚数、单株粒数和分枝数多的品种类型。Gray correlation analysis was conducted for 15 species from soybean regional pilot project in Anyang Academy of Agri- cultural Sciences. The results showed that among all yield influencing traits, the bean pad mumber per plant was the most important, and factors of bean mumber per plant, branch number per plant, 100-seed weight and plant height had relatively small influence, and the nod number the least influence. It is concluded that under the ecological conditions in Anyany, the strategy for high-yielding soybean breed- ing is to pay attention to select higher per plant bean pad number, seed number and branch number based on stable per plant seed num- ber and 100-seed weight.
