Fig. 2From: An RTM-GWAS procedure reveals the QTL alleles and candidate genes for three yield-related traits in upland cottonThe RTM-GWAS results of BN. a Manhattan (left) and quantile–quantile plots (right) of BN. Each dot indicates one SNPLDB marker. The horizontal dashed red line represents the normal significance threshold of 0.05. b Distribution of allele effect of the significant SNPLDB loci for BN. The bars above the abscissas mean positive effect values improving fiber quality, while the bars below the abscissas represent negative effect values reducing fiber qualityBack to article page
