These QTL on 2AL are located between Xgwm71.2/Xgwm558 and Xgwm294, with an interval of 22 cM according to the consensus map of Somers  or 16.1 cM according to the ITMI map (http://wheat.pw.usda.gov/ggpages/SSRclub/GeneticPhysical/). From this TGW-QTL-rich region, only one gene, TaCwi-A1, has been isolated thus far between the Xgwm 71.2 and Xbarc15 deletion bin ‘C-2AL1–0.85’, which is adjacent to the centromere . By integrating the information from the ITMI (http://wheat.pw.usda.gov/ggpages/SSRclub/GeneticPhysical/) and ‘Yu 8679 × Jing 411’ SSR + SNP  maps, the location of TaFlo2-A1 was inferred on deletion bin ‘2AL1–0.85-1.00’. Hence, the TaFlo2-A1 is a TGW-related gene located on the distal deletion bin of chromosome 2AL, and the molecular marker ‘TaFlo2-InDel8’ is an addition to the kit of wheat breeders for marker-assisted selection.
