Abstract
Soybean grain with high protein and high oil contents is desirable in the global market for its special food application. In this study, we intent to determine genetic variation for seed protein and oil content and to utilize the traits to develop new improved cultivar to both traits. Thirteen genotype of soybean were grown in a randomized block design with three replications for two cropping seasons. Seed weight/plant, grain yield m2, seed protein and oil content were observed from each plot. Except for grain yield, cropping seasons did not affect all traits observed in this study. There were large variation found among genotypes for seed weight, grain yield and seed protein content but not for seed oil content. Grain yield was positively correlated to seed weight but negatively correlated to seed protein content. Seed oil content did not significantly correlated to any traits. The result indicated that all traits may be utilized as selection criteria in a soybean
breeding program and it is possible to develop a cultivar with high yield as well as high seed protein or high seed oil content.
