Fig. 1. Confirmed QTLs were projected on the soybean composite linkage map. The confidence interval region of a QTL is indicated by the length of a thin line above the linkage group map. The position of a QTL is indicated by the vertical thin line. The soybean accession on each thin line indicates that a QTL was reported in this accession. The number in parentheses following the accession indicates races—1, race 1; 2, race 2; 3, race 3; 5, race 5; 6, race 6; and 14, race 14. The letters in parentheses following the race indicates studies where QTLs were reported (a) Concibido et al., 1994; (b) Concibido et al., 1996; (c) Concibido et al., 1997; (d) Glover et al., 2004; (e) Guo et al., unpublished (PI 90763); (f) Heer et al., 1998; (g) Meksem et al., 2001; (h) Mahalingam and Skorupska et al., 1995; (i) Wang et al., 2001; (j) Webb et al., 1995; (k) Yue et al., 2001a; (l) Guo et al., unpublished (PI 404198A); (m) Yue et al. (2001b). QTLs detected in PI 4376122 (Lu et al., unpublished) were not projected because the study is in progress.
