Abstract：Most quality traits of wheat (Triticum aestivum L.) are quantitative traits controlled by multiple genes, and discovery of main effective quantitative trait locis (QTLs) which control quality related traits in wheat can provide useful information for molecular breeding. The 585 QTLs of wheat quality related traits reported were collected, and 264 meta quantitative trait locis (MQTLs) were predicted by meta-analysis which included 34 MQTLs for water absorption (ABS), 26 MQTLs for flour protein content (FPC), and 84 MQTLs for grain protein content (GPC), 52 MQTLs for kernel hardness (KH), 39 MQTLs for sedimentation value (SV) and 29 MQTLs for wet gluten content (WGC). Then the technology based on BioMercator software and marker projection were used to integrate QTLs on the wheat quality related traits which were from different genetic mapping population into a reference map. The MQTLs on wheat quality related traits were inhomogeneous distribution on chromosomes, and some QTLs concentrated clusters. The finding of real QTLs section (or site) which controlled wheat quality related traits and the construction of integration map provide reference data for exploring genes on wheat quality related traits, candidate genes and marker-assisted breeding.
