摘要： Expressed sequence tag-simple sequence repeat (EST-SSR), simple sequence repeat (SSR), and sequence-related amplified polymorphism (SRAP) markers were used to construct the first intra-specific genetic linkage map for B. oleracea var. alboglabra. In addition, QTL locations were determined for bolting and flowering traits. A total of 189 polymorphic marker loci were detected in the two parents, with 45 marker loci not located on any linkage group (LG). The remaining 144 loci defined ten LGs and included 69 EST-SSR loci, three SSR loci, and 72 SRAP loci. The length of the map was 1,173.8 cM, the average distance between loci was 8.15 cM, and the proportion of segregation distortion loci was 25.7%. Three QTLs controlling bolting time and two QTLs controlling flowering time were detected in the F-2:3 generation, which explained 37.07% and 18.44% of the phenotypic variation, respectively. Two QTLs controlling bolting time and two QTLs controlling flowering time were detected in the F2 generation, which explained 27.90% and 25.59% of the phenotypic variation, respectively. In both generations, QTLs ftB.1 and ftA.1 were located on LG5, and the distance between the two QTLs was only 1.0 cM, suggesting that they could be at an identical locus. These results provide a useful reference for future QTL studies on bolting and flowering time in B. oleracea var. alboglabra, and can be used to identify markers linked to these QTLs for marker-assisted selection in commercial breeding programmes.
