Genome-wide association mapping of QTL underlying seed oil and protein contents of a diverse panel of soybean accessions

To investigate the genetic basis of variation in oil and protein contents in soybean seeds, a diverse collection of 421 mainly Chinese soybean cultivars was genotyped using 1536 SNPs, mostly from candidate genes related to acyl-lipid metabolism and from regions harboring known QTL. Six significant associations were identified for each of seed oil and protein contents which individually explained 2.7–5.9% of the phenotypic variance. Six...
