Fig. 2. QTL regions identified by environment for the traits daidzein, genistein, glycitein, and total isoflavone content using interval mapping (a) and composite interval mapping (b). QTL with a LOD score > 2.0 are presented to the right of each linkage group with a vertical bar. Letters above the vertical bars indicate the corresponding trait. D, daidzein; G, genistein; GY, glycitein; T, total isoflavone. A dashed line between linkage groups indicates linkage inferred from the linkage of SSRs in the study by Cregan et al. (1999). SSR loci are listed to the right and map distances in centimorgans are listed to the left of each linkage group. Loci with segregation distortion (P < 0.05) are indicated with an asterisk.
