Protein and oil are two of the important quantitative traits closely related to the nutrient quality in soybean(Glycine max [L. ] Merry). The content and yield of protein and oil have become one of the main goals in soybean breeding. For soybean breeding programs, understanding the inheritance is of importance. Genetic analyses of protein and oil content in soybean seed have been reported. Most of the studies showed that protein and oil content are quantitatively inherited. Genetic effects, heritability and correlation of protein and oil content in soybean seeds have been estimated.
