Locations of 5 QTL underlying cyanogenic potential. Box-bars with extending lines at the right side of the linkage group indicated the region within 1and 2 LOD units of the peak. The QTL names are on the right of each box-bar. The significance of Kruskal-Wallis analyses are shown at the left side of the linkage group (* is P ≤ 0.1, ** is P ≤ 0.05, *** is P ≤ 0.01, **** is P ≤ 0.005, ******* is P ≤ 0.00001). All symbols colored with blue, red and pink, refer to the analysis in 2008 at Rayong, 2009 at Rayong and at Lop Buri, respectively.
