图2 粒长、粒宽和粒厚显著相关的SNP分布统计 红色、蓝色和黄色背景分别代表粒长、粒宽和粒厚; 竖线表示籽粒大小性状关联到的位点在染色体上的位置; 比例尺表示关联位点的显著水平; 直方图的高度表示位点的频率。

Fig. 2 Distribution of SNPs significantly correlated with kernel length (KL), kernel width (KW), and kernel thickness (KT) Red, blue, and yellow backgrounds represent KL, KW, and KT, respectively. Vertical lines indicate the position on the chromosome of the loci associated with kernel size traits. The scale bar indicates the significance level of the association site; the height of the histogram indicates the frequency of the loci.
