Quantitative trait loci (QTL) mapping and marker development are essential steps in any molecular breeding programme. In this study, QTL for photosynthetic pigment concentration were identified using a doubled-haploid (DH) population of 112 lines derived from an F-1 hybrid of Pak Choi, 'Shuly', obtained from a cross between Brassica rapa lines SW-13 and SU-124 through microspore culture. QTL mapping was carried out using a modification to the map of 'Shulv. Alignment of the linkage groups was carried out with those of reference B. rapa maps, allowing the assignment of these groups as A01-A10. In total, 11 QTL were associated with photosynthetic pigment concentration and identified on linkage groups A05, A08, and A10. The maximum phenotypic variance for a single QTL was 38.0%. Markers closely linked to these QTL could assist in the development of Pak Choi cultivars with increased yield, due to having improved photosynthetic capabilities.
