*LG, linkage group; Chr, probable chromosome based on fluorescent in situ hybridization data. ^†Physical chromosome size was based on the relative size of chromosomes [48] and an estimated 300 Mb genome size. ^‡Total number of markers in each linkage group. ^§When two or more markers had 0% recombination, we selected a single marker to generate the maps. ^¶Calculated as the unadjusted map length divided by the number of intervals (mapped markers minus 1). The interval spacing reported under the total is 1,134.84 cM divided by 202 intervals.
