The results shown that: Latitude and year's weather conditions affected protein content of soybean seeds importantly. Elevation affected oil content significantly. There was important difference in protein / oil content among different eco - geographical regions. The zone, in which there was the highest content of protein / oil, was that one with latitude from 0°to 20°59′ . And in this zone, there were different elevation regions, in which protein or oil content was the highest. For high pro-tein, it was the elevation region with 500 - 1000 m; for oil, it was 0~ 500 m. Protein / oil content was also different among different years. However, the changing range among years in Tropical and Subtropical regions was smaller than that in Temperate Regions. The relationship between protein / oil content and latitude, elevation or soil pH in the regions outside the Tropic of concerned and the Tropic of Capricorn was more significant than that in the region inside Regression Lines, i. e.
