图3 耐深播主效位点qMES20-10的精细定位
A: 目标QTL qMES20-10所在的染色体区段。B: 用BC₄F_2:3家系进行精细定位。R1~R9表示9种不同的重组类型, 黑色和白色区段分别代表来自亲本3681-4和X178的染色体片段。^**和 ^*分别表示在0.01和0.05水平下差异显著, NS表示无显著差异。

Fig. 3 Fine mapping of the major QTL qMES20-10 for deep-seeding tolerance
A: the locus of target QTL qMES20-1 on bin 10.06. B: fine-mapping utilizing BC₄F_2:3 lines. R1-R9 represent the nine recombinant types. Black and white bars represent chromosomal segments derived from 3681-4 and X178. ^** and ^* mean significant difference at the P < 0.01 and P < 0.05, respectively; NS means no significant difference.
