Figure 2

A. Hbs-1 in the IT84S-2246 x TVu14676 population. The major locus for the heat-induced browning of seed coats phenotype was mapped using datasets from two experiments. Hbs-1 spanned 49.51 cM to 50.69 cM on linkage group 9. SNP marker 1_0032 was the most significant marker for both experiments accounting for 28.3% and 34.1% of the phenotypic variance and is highlighted in red on the linkage group. The significance threshold is indicated by the horizontal broken line. B. Hbs-3 in the IT84S-2246 x TVu14676 population. The minor locus for the heat-induced browning phenotype was mapped using two experimental datasets (Interval Mapping analysis shown). Hbs-2 spanned 8.67 cM to 20.97 cM on linkage group 3. SNP markers 1_0280, 1_1534 and 1_1404 shared the same marker bin, accounting for 6.2% and 6.8% of the phenotypic variance and are highlighted in red on the linkage group. The significance threshold is indicated by the horizontal broken line on the graph.
