In brackets, the population used for QTL mapping is displayed (BC backcross, DH doubled haploid, NILs near-isogenic lines, RILs recombinant inbred lines). A detailed description of the QTLs is given in the Supplementary Material
aNames of the QTLs consisting of the qualifier “Q”, the trait abbreviation, the determined population, the mapped chromosome and a QTL number to distinguish between QTLs on the same chromosome. Markers with a distance ≤20 cM were considered to be a single QTL
bChromosomal location of the SSR markers
cPosition of the SSR markers on the chromosome in centiMorgan (cM) (von Korff et al. 2004). If several markers were significant, the cM range is given
dBin marker class following Kleinhofs and Graner (2001) and Costa et al. (2001). In the case of several significant markers, the Bin class range is displayed. An additional number in brackets gives the Bin class following Marcel et al. (2007). As the Bin class of Marcel et al. (2007) was available only for some markers, in the case of several significant markers belonging to the same QTL, these markers are given in italics
