Abstract: The isoperoxidase electrophoregrams of 20 millet varieties which were collected from Yellow River valley in Shandong provinceve were analysed by suing PAGE and polar ordination method The result showed that the 20 varieties could be classified into 6 groups but there were large similarity in electrophoregrams among the varieties and the groups which suggested that these varieties from different districts of Shandong province were closely related and that the classification on molecular levelw as more accurate than on morphological or ecological bases Polar ordination of isoenzyme electrophoregrams could identify difference quantitatively among millet varieties.

Key words: Millel Varieties, Isoperoxidase, Polar ordination
