摘要： Spikelets compactness (SC) plays an important role in the yield improvement and Fusarium head blight (FHB) resistance of wheat. In this study, 151 recombinant inbred lines (RIL) derived from a cross between Yangmai 4 (YM4) and Yanzhan 1 (YZ1) and 143 RIL derived from a cross between Yangmai 5 (YM5) and YZ1 were used to construct two wheat hexaploidy genetic linkage maps, evaluate SC across three years and identify quantitative trait loci (QTL) for SC. A total of seven QTL were identified in two populations and explained the phenotypic variation ranging from 6.27% to 22.49%. Four QTL were co-located in two genomic regions on chromosomes 2D and 6B, namely, QSc-2D and QSc-6B, respectively. Comparison analysis showed that QSc-6B is a novel QTL, whereas QSc-2D was located in the interval of Rht8. Significant additive effects of QSc-2D and QSc-6B on SC were observed in two RIL populations. Moreover, the positive alleles of these two QTL extremely significantly increased grain number per spike (GNS) but did not have a significantly negative effect on thousand-grain weight (TGW), kernel length (KL) and kernel weight (KW). Whether in spray or point inoculation, QSc-6B did not significantly influence FHB resistance in two populations. However, QSc-2D significantly affected FHB resistance in spray inoculation in YM4/YZ1 population. A breeder-friendly Kompetitive Allele-Specific PCR (KASP) marker KASP_6B for QSc-6B has been developed and verified in a set of 181 wheat cultivars/lines. Furthermore, we preliminary analysed the candidate genes within the physical interval of QSc-6B by sequence similarity, spatial expression patterns and collinearity analysis. TraesCS6B03G1206900, TraesCS6B03G1214800 and TraesCS6B03G1218300 show specific expression in spikelet. These results provide valuable information for map-based cloning of QSc-6B and a useful tool for wheat breeding.
