Figure 6. Quantitative trait loci (QTL) for brittle rachis and threshability. QTL detected on chromosome 5A in the Triticum aestivum ssp. tibetanum Shao population from accessions Q1028×ZM9023.
Marker positions are shown on the right of the linkage map, and distances between loci (in centimorgans, cM) are shown on the left. The vertical dashed line indicates the significance threshold (LOD = 2.5).
