摘　　要：以13个油用向日葵新品种(系)为试验品种,运用灰色关联度分析法,分析了8个主要农艺性状与产量关系的密切程度。结果表明:油用向日葵主要性状对产量的关联顺序依次是:花盘直径>百粒重>茎粗>结实率>株高>生育期>含油率>籽仁率。花盘直径对产量影响最大,籽仁率对产量的影响最小。In 13 oil sunflower varieties （lines） to test the new varieties, using the method of grey correlation analysis,we analyzed the close degree of 8 main characters and yield relationship was done.The results showed that： oil sunflower was mainly associated with the order for production traits were： disk diameter〉 hundred-grain weight〉 stem diameter〉 setting rate〉plant height〉growth stage〉 oil content〉 seed kernel rate. Disk diameter had the greatest impact on the yield,but seed kernel rate had the least impact on the yield.
