QTL mapping and QTL-seq results. (a), QTL peak map of soybean chromosome 20 from 178 RIL lines across six tested environments. (b), Overlapping relationships among SPC quantitative trait loci (QTLs) in this and previous studies (since 2010). For facilitate comparison, all results are uniformly converted to version glyma 1.0. (c), SNP-index graphs generated from whole-genome resequencing using a QTL-seq analysis. The black lines indicate the average SNP index based on a 1-Mb genomic interval with a 100-kb sliding window. Blue and red lines represent the statistical confidence intervals at significance levels P < 0.05 and P < 0.01, respectively
