A description of the mapping population, molecular markers employed, and map positions may be found in Lexer et al. (2003a) and Rieseberg et al. (2003).

^aLowercase letters following linkage group numbers refer to fragmented segments in the Rieseberg et al. (2003) population and do not correspond to the uppercase letters employed in Figure 2 and Figures S1–S5 (available at http://www.genetics.org/supplemental/).
