%X In this study, quantitative trait loci (QTLs) with additive effects, epistatic effects for CNSB specific volume in bread wheat (Triticum aestivum L.), were studied in cultivars Huapei 3 and Yumai 57 (Triticum aestivum L.). The DH population and the parents were planted in 2007 and 2008 in Tai¨An and 2008 in Suzhou. QTL analyses were performed using the software of IciMapping v2.2 based on the mixed linear model. Five putative QTLs for CNSB specific volume were detected on 5 chromosomes where single QTLs explained 5.11% to 9.75% of phenotypic variations. All of them had negative effects on specific volume and were contributed by Yumai 57 alleles. Qsv-1B was detected in both environment 1 and 3 with 13.88% and 4.83% phenotypic variations which had positive effects and was transmitted by Huapei 3 alleles. Fourteen pairs of QTLs with epistatic effects were detected for specific volume. Seven major QTLs, Qsv-1B/Qsv-3A, Qsv-2D/Qsv-3A, Qsv-3A/Qsv- 5B1, Qsv-1B/Qsv-6D, Qsv-2D/Qsv-4D, Qsv-4A/ Qsv-6B and Qsv-3A/Qsv-7D could account for 13.88%、20.39%、18.88%、12.31%、18.78%、11.98%, and 17.05% of the phenotypic variation of specific volume. The information obtained in this study will be useful for manipulating the QTLs for CNSB specific volume property by molecular marker-assisted selection (MAS).
