摘　　要：以2019-2020年国家冬麦区黄淮北片水地组区试试验结果为依据,对包括对照在内的14个品种的主要农艺性状与产量进行灰色关联度分析,以期为黄淮小麦育种提供参考。结果表明主要农艺性状与小麦产量的关联度大小为生育期>基本苗>株高>667 m^(2)穗数>成穗率>千粒重>容重>穗粒数。在山东小麦育种中应注重对生育期、基本苗、株高及667 m^(2)穗数这几个重要性状的选择。Based on the results of regional test of irrigated field group in winter wheat region from 2019 to 2020 in north part of Huanghe River and Huaihe River watershed,the main agronomic characters and yield of 13 varieties including control were analyzed by grey correlation degree,it is expected to provide a reference for wheat breeding in Huanghe River and Huaihe River region.The results showed that the correlation degree between main agronomic traits and wheat yield was as follows:growth period>basic seedling>plant height>ear number per mu>ear rate>1000 grain weight>bulk density>grain number per ear.In Shandong’s wheat breeding,the selection of growth period,basic seedling,plant height and ear number per 667 m^(2) should be paid attention.
