STUDY ON THE STABILITY OF THE YIELD AND THE MAIN SEED QUALITY CHARACTERS IN HIGH PROTEIN SOYBEAN CULTIVAR

Based on the method of Yu strong's stable parameters analyses .we analysed nine high protein soybean cultivars,both on their stability of the yield and the main seed quality characters. It was found that the high protein soybean cultivars Tong Non 9,Tong Non 10 and Tong Non 11 are high yield,high protein, better seed appearance quality and stability. It was also faund that if a cultivar contained higher protein,the rate of full seeds was higher,and the rate of seed coat mottling and the percentage of damaged seeds were lower, then the quality characters were more stable. The chemical component was more stable than seed appearance quality. Meanwhile,we analysed the relationship between stability of the protein and some plant characters,and the relationship between variation of the protein and the climatic factors from flowering to ripening.
