Fig. 2. Molecular linkage map of 97 RFLP and 1 SSR loci and location of the QTLs from the combined analysis. Numbers to the right of the chromosomes indicate the cumulative distance in centimorgans (cM). The small, filled boxes along the chromosome indicate the positions of the bin boundaries. The numbers between the bin boundaries indicate bin number. The open circles along the chromosomes indicate approximate centromere position. The Bars indicate the region in which LOD scores exceed 3.5 and the number within the bars indicates the maximum LOD score and its position.
