Locational variation of chemical components in soybean seed of high-protein lines

Soybean seeds are one of the most improtant sources of protein and oil in the world. Recently, emphasis has been placed on the chemical composition of soybean seeds for the processing soybean foods. This study was conducted to determine the influence of location on chemical composition of 3 genotypes of soybean seeds grown at 6 locations. On the mean value, Cheju showed the highest in crude protein content whereas Mokpo was the lowest, on the other hand, Mokpo showed the highest in crude lipid content. It was suggested that environmental factors contributed greatly to seed chemical composition. On the correlation coefficient among the chemical constituents and yield, it was shown that the protein content was negatively influenced by lipid and carbohydrate content but yield was not correlated by chemical constituents. There was a positive correlation between protein content and yield, and a negative correlation between lipid content and yield, only in Cholwon. No significant effect of interaction between location and variety was found in the analysis of variance for seed crude protein and lipid content. The results show that soybean lines having high protein or lipid can be selected regardless of locations.
