Figure 2. Comparison of the soybean A1 and B2 linkage groups
(right) constructed by the Jinong17 × Jinong18 RIL population (right)
with the corresponding linkage group of GmComposite 2003 genetic map
(left). The genetic distances (cM) are shown on the left side and the
markers on the right. The common markers between the two maps are
highlighted in yellow boxes and connected by black lines, except for the
ones of whose positions are rearranged which are connected by red lines.
2.3. QTL mapping for isoflavone content
in soybean seeds
In total, we identified 22 main effect QTLs associated with the main
soybean isoflavones including daidzin, glycitin and genistin and total
isoflavone content, explained 0.35% to 2.06% of the phenotypic
variation. The detailed information for all QTLs is shown in Table 2.
All QTLs located on 11 linkage groups. The range of LOD scores and
additive effects for the QTLs ranged from 2.98 to 37.30 and −0.34 to
1.27, respectively.
