Abstract:
Five high oil content soybean were selected and four crosses were made.The correlation and path-coefficient of oil content，protein content and the major agronomic characters in F2were analyzed.The results indicated that oil content in F2was extremely negatively correlated with protein content，node number of main stem，seed weight per plant and 100-seed weight in F2；the protein content had significant positive correlation with node number of main stem，pod number per plant and seed number per plant；seed weight per plant had significant positive correlation with nodes number of main stem，pod number per plant，seed number per plant and 100-seed weight.The direct minus effect of seed weight per plant to oil content and seed number per plant to protein content was the most significant，the total content of protein and oil was mainly affected by the indirect minus effect of pod number per plant，the most effective factor for seed weight per plant was seed number per plant.
