Study on Relationship Between Different Growing Phases and Quality Breeding in Soybean

选择脂肪含量高的材料应选择播种到出苗日数短、开花期较晚和成熟期较早的材料为宜；选择蛋白质含量高的材料应选择出苗到开花时间短、开花期长和成熟期较晚的材料为宜。

The relationships of oil,protein to growing phases were studied in this paper with 68 test materials.The result shows:it's the best for soybean breeding of high oil content to choose the materials with characteristics of the short dates from sowing to emergence late_flowering early_maturing phases;it's the best for soybean breeding of high protein content to choose the materials with characteristics of the short dates from the emergence to flowering and the long flowering and growing periods.
