运用灰色关联度分析方法，对15个冬小麦新品种(系)的产量与7个主要农艺性状的关联度进行了分析。结果表明，有效穗数与产量的关联度最大，r值为0.696 4；其次是株高、基本苗、穗长、千粒重，r值分别为0.683 9、0.682 0、0.681 8、0.675 9。

By using the gray correlation analysis method， correlation degree for yield of 15 new winter wheat varieties (lines) and seven major agronomic traits were analyzed. The results showed that there has a maximum correlation degree between effective spikes and yield， r value was 0.696 4， and the next were plant height， population density， ear length， grain weight， r values were 0.683 9， 0.682 0， 0.681 8， 0.675 9， respectively .
