图5 qTBN5进一步定位及连锁标记开发 a: 交换株代换作图定位qTBN5, L1为昌7-2, L5为郑58, L2~L4为重组株, **表示在 0.01水平差异显著; b: 标记检测郑58和昌7-2及BC1F2世代部分单株基因型, 红色M13为通用引物序列。

Fig. 5 Further mapping and linked markers development of qTBN5 a: qTBN5 detected on the substituted segments in recombinant lines; L1: Chang 7-2; L5: Zheng 58. L2-L4: recombinant lines; “**” shows significance at P<0.01 as determined by t-test. b: genotypes identification of qTBN5 in BC1F2 backcross population. M13: Red indicates universal primer sequences.
