图6 qPH3.2.2的精细定位 A: 红色区域为qPH3.2初定位区间, 绿色和蓝色分别是qPH3.2.1和qPH3.2.2重定位区间; B: 利用2个跨叠系N4和N5定位qPH3.2.2; C: qPH3.2.2精细定位结果。N代表评估表型的单株数目。AA表示携带qPH3.2.2位点的等位基因; aa是以W2为背景的等位基因。

Fig. 6 Fine mapping of qPH3.2.2 A: the pre-mapping result of qPH3.2 located on red bar, green and blue bars indicate the remapping results of qPH3.2.1 and qPH3.2.2, respectively; B: the mapping results of qPH3.2.2 using N4 and N5 overlapping lines; C: the fine mapping results of qPH3.2.2; N indicates the number of the evaluated individuals in each line. AA means the allele derived from qPH3.2.2; aa indicates the allele derived from genetic background W2.
