The component and content of fatty acid are important standard to evaluate the quality of soybean (Glycine max L. ). Although more and more QTLS related with fatty acid were developed, but the accuracy and validity of these QTLs didnt show very well in different populations by different method of data analysis, or in different environment. In this paper, 83 fatty acid QTLs were collected. They were all projected on the public genetic linkage map, Soymap2,by BioMercalor2.1. And a consensus genetic map from individual map with QTLs, genes and other loci was built. A method of meta- analysis was used to deduce the true QTLs' locus with confidence interval of 95%. Nineteen true QTLs were acquired. All the QTLs were mapped on 10 linkages group, mainly distributed on A1, B2, D1b, D2,E,G,and L linkages group as clusters. Most QTLs were related with multiple trait of fatty acid in soybean. The results narrowed down the reported QTLs, which provided the base for QTL fine mapping and gene cloning.
