图5 WinQTL复合区间方法确定花色QTL连锁群位置 图A中, X轴表示19条染色体, Y轴分别表示LOD值和加性效应a (H1); 横线表示LOD阈值线。图B、图C分别表示在7号染色体和13号染色体检测到的一个花色QTL位点; X轴表示对应染色体上的遗传距离, Y轴分别表示LOD值和加性效应a (H1); 横线表示LOD阈值线。

Fig. 5 Chromosomal location of QTL for petal color by WinQTL CIM X-axis represents 19 chromosomes, and Y-axis represents the LOD value and the additive effect a (H1) in Figure A; the horizontal line represents the LOD threshold line. Figure B, there is a represent QTL of petal color in figure C detected on chromosome 7 and chromosome 13, respectively; X-axis represents the genetic distance on the corresponding chromosome, and is marked with the corresponding linkage marker position, Y-axis represents the LOD value and the additive effect a (H1), respectively; the horizontal line indicates the LOD threshold line.
