In this paper , we analyzed the fat and protein content of 200 soybean varieties released in Heilongjiangprovince during 1951 -2000 .The results showed that the highest fat content was in the 1960’ s and 1970’ s , which were21 .67 % and 21 .20 %respectively .The lowest fat content was in the 1990’ s , which was 20 .03 %.The average fat contentof 200 varieties was 20.74 %.The average protein content of 200 varietiesd was 40 .25 %.To study the 172 varieties in different ecological region during 1951 -2000 .The results showed that the content offat and protein had apparent geographic distribution .The high fat region was in the western dry soil region .The low fatregion was in northern high latitude region .The high protein region was in southern black soil region and eastern wetland.The low protein region was in western dry soil region .According to the apparent geograsphic distribution phenomena, we may carryout the distribution plant and specialization production of the super quality soybean varieties .
