A principal component analysis and cluster analysis were made of 12 biological characters of 30 spring soybean new strains bred in recent years.The results show that with cluster analysis based on genetic distance 30 spring soybean new strains could be divided into four groups of different characteristics.With principal component analysis some comprehensive character factors such as plant height,growth period,branch number,pod number and grain weight were selected and a preliminary comprehensive evaluation of the varieties（strains） was made to provide useful information for soybean breeding.
