Qtl that control seed protein, oil, and fatty acids contents

Plant breeders and farmers aim at developing soybean cultivars and lines with high seed protein and oil contents, high oleic acid contents, and low palmitic, stearic, and linolenic acid contents. Therefore, different types of molecular markers and mapping populations have been used to genetically map quantitative trait loci (QTL) that control seed protein, oil, and fatty acids in soybean using biparental populations as well as wild soybean accessions via genome-wide association studies (GWAS). Here, we summarized QTL mapping data for seed protein, oil, and fatty acids content from 1992 to 2000. Candidate genes identified within these QTL regions are also summarized. These findings are promising; however, decades of followed studies are still needed to fine map these regions, identify candidate genes, and understand the full extent of the metabolic pathways involved in these traits.
