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
