摘　　要：研究了大豆品种Ｗｉｌｌｉａｍｓ的蛋白质和脂肪含量在世界各地的表现。结果表明，在不同生态地理区域间，大豆蛋白质和脂肪含量有很大的差异。纬度０°－２０°５９’区域内蛋白质和脂肪含量最高，但在此区域内，海拔５００—１０００米的中等海拔地区蛋白质含量最高，０－５００米的低海拔地区脂肪含量最高。不同年度间蛋白质、脂肪含量亦不相同。但是低、中纬度的热带和亚热带地区年际间含量变化小于中高纬度的温带和冷凉地区的年际变化。北回归线以北、南回归线以南的地区蛋白质和脂肪含量与地理纬度、海拔高度、土壤酸碱度的相关显著性高于回归线以内的赤道雨林、热带草原区。就世界范围来看，大豆的蛋白质含量与脂肪含量负相关高度显著。蛋白质与产量负相关亦高度显著，但年度之间相关程度不同；脂肪含量与产量正相关接近显著，但受环境影响很大，有的年份、有的地区相关不显著。The performance in world-wide of protein and oil content of a soybean cultivar, Williams,was studied. The results showed that there was significant difference in protein/oil content amongdifferent ecogeographical regions. In the zone with 0°- 20°59', latitude, there were the highestcontent regions of protein and oil. But within the zone the highest region for protein content wasthe part with 500-1000m of elevation and the highest region for oil content was the part with 0-500 m of elevation. There was different protein and oil content in different years, but the variation among years in tropical and subtropical zones was smaller than that in temperate zone andcold region.The significance of correlation between protein/oil and latitude, elevation or soil pH in theregions outside of the regression lines was higher than that inside of the repression lines, and in equatorial rainforest region and tropical grassland region.In world-wide, there was high negative significant correlation between protein and oil content. Also the negative correlation between protein and yield was highly significant. But therewas some different correlation level in different years. The positive correlation between oil content and yield was close to significant, and it was influenced by environment. In some years orsome regions, this correlation was not significant.
