Figure 4.

(A) The −log ^p-value for each SNP marker in the chromosome 5 QTL support interval. Values were plotted against their respective physical positions (Mbp). The blue line represents the significance threshold (p = 1.6 × 10⁻⁴). (B) The −log ^p-value for each SNP marker in the chromosome 6 QTL support interval. Values were plotted against their respective physical positions (Mbp). The blue line represents the significance threshold (p = 1.6 × 10⁻⁴). (C) Effect of SNP marker Ha6_7633946 on CGT number. The box plot of each allele at SNP marker Ha6_7633946 shows the significant association with CGT number in the validation panel (p = 0.0004). The horizontal bar (bold) indicates the median, discontinuous lines represent the upper and lower quartile, and the outlier data are labeled by a circle. (D) Effect of SNP marker Ha5_10149906 on CGT number. The box plot of each allele at SNP marker Ha5_10149906 shows the significant association with CGT number in the validation panel (p = 0.004). The horizontal bar (bold) indicates the median, discontinuous lines represent the upper and lower quartile, and the outlier data are labeled by a circle.
