摘要： 为改良河西地区食用型向日葵品种,采用灰色关联度分析法对8个食用型向日葵品种的10个农艺性状分别与产量、品质、发病率进行灰色关联度分析。结果表明生育期和茎粗是影响子实粗蛋白含量的主导因子；子实形状是影响子实粗脂肪含量的主导因子,同时子实的宽、长也是影响子实油酸、亚油酸含量的主导因子；子仁率和生育期是影响植株发病率的主导因子；百粒重和盘径是影响产量的主导因子。以上几个指标可以作为河西地区选择食用型向日葵品种的参考指标, 为科学合理的选择食用型向日葵品种, 保证食用型向日葵品质提供参考。

Abstract: The paper aims to improve the edible sunflower varieties in Hexi area. We analyzed 10 agronomic characters of 8 edible sunflower varieties with yield, quality and incidence rate respectively by adopting grey correlation analysis. The results showed that: the dominant factors that influenced the content of coarse-protein were the fertility period and stem thickness; the dominant factor that influenced the content of coarse-fat was seed shape, and the width and length of seed were also the dominant factors affecting the content of seed oleic acid and linoleic acid; the seed kernel rate and fertility period were the dominant factors affecting the incidence rate of plant; the 100-grain weight and sunflower head diameter were the dominant factors affecting the yield. The above indexes can be used as reference indexes for choosing edible sunflower varieties in Hexi area.
