Fig. 3From: Fast-track breeding system to introduce CTV resistance of trifoliate orange into citrus germplasm, by integrating early flowering transgenic plants with marker-assisted selectionGenetic linkage map using the BC1 population obtained from the cross between ‘Hyuganatsu’ and F1–2-11. The CTV resistance locus (●) and T-DNA integrated region locus (▲), located on LG2 and LG9, respectively. CAPS markers assigned on the linkage map are utilized for graphical genotyping analysis, for the evaluation of the genetic background substitutions from the trifoliate orange onto the citrus germplasm. The solid ring indicates a QTL controlling a trifoliate leaf, and the hollow black ring indicates a QTL controlling the long thornsBack to article page
