Fig. 2: Statistics of trait-associated variants detected by meta-analysis of GWAS results in 6 rice panels.

a Lead variants of QTLs from GWAS and meta-analysis for different phenotypes. b Illustrated of the 156 QTLs along the rice chromosomes. The colors of the QTL labels represent different phenotypes, as listed in the legend. The density of SNP + PAV is measured in a 100 Kb window for each chromosome. QTLs labeled with underscores were identified by both GWAS and meta-analysis. Inverted triangles in red indicate that overlapping QTLs of different phenotypes. c Percentage increase in QTL number by meta-analysis relative to individual GWAS results. d Percentage increase in heritability explained by QTLs of meta-analysis relative to individual GWAS results. In (c, d), the error bands indicate 95% confidence intervals, p-values were calculated by two-sided spearman correlation test.
