摘要： 应用灰色关联度分析方法,对适合我市的夏大豆育成品种进行分析,结果表明:各农艺性状与蛋白质含量的关联度由大到小依次是:产量>生育日数>百粒重>单株荚数>株高>单株粒数>脂肪含量>始花(R1)~成熟(R8)日数>主茎节数>出苗~始花(R1)日数;对蛋白质含量影响最大的是产量,影响较大的是生育日数、百粒重、单株荚数。与脂肪含量的关联度由大到小依次是:始花(R1)~成熟(R8)日数>株高>生育日数>主茎节数>产量>蛋白质含量>单株荚数>单株粒数>百粒重>出苗~始花(R1)日数;对脂肪含量影响最大的是始花(R3)~成熟(R8),影响较大的是株高、生育日数、单株节数。

Abstract: In the paper the correlation degree among main agronomic characters and quality characters of summer soybeanvarieties.The results showed that: the order of main agronomic characters and content of protein was yield> growth period>100 seed weight> number of pot per plant> height> number of seed per plant> content of fat> days during R1- R8> number of caulis?? node> days during seedling to R1.The most effective factor for the content of protein was yield. Growthperiod, 100 seed weight and number of pot per plant ranked after it .The order of main agronomic characters and content offat was days during R1- R8> height> growth period> number of caulis?? node> yield> content of protein> number of potper plant> number of seed per plant> 100 seed weight> days during seedling to R1.Themost effective factor for the contentof fat was days during R1- R8.Height, growth period and number of caulis?? node ranked after it .

Key words: Summer soybean, Content of protein, Content of fat, Agronomic character, Grey correlat ive analysis
