Abstract: The ecological adaptation of soybean was discussed by means of the relational analysis of the grey system theory aeeording to soybean yield and its charaeteristics. The results showed that the relational coefficient and grade of grey system theory was the most practical parameter. Using a proportion value of ecological and produetion characters to production as a base for characteristics selecting on soybean breading is a good and practical method.
