图4 大麦7个连锁群SSR位点的连锁不平衡分布箭头指示连锁群区域, 对角线上方为成对位点间 D′ 值, 下方为成对位点间LD的支持概率。 A: 地方品种; B: 栽培品种, 椭圆圈显示较高水平的LD位点分布。
Fig. 4 Distribution of LD among SSR loci on 7 linkage groups of barley Double-headed arrows show the region of linkage groups. D ′ value of the corresponding marker pair and its P- value are shown in the upper and lower triangles, respectively. A: landrace; B: developed variety. The oval circles show distribution of LD loci in high levels.
