Fig. 3. A graph of LOD score versus map distance (in centimorgans) in the upper portion of soybean linkage group I for seed protein, oil, and yield in 1996 and 1997. The LOD scores were derived from linear regression (LR- diamond symbols), simple interval mapping (SIM-thin lines), and composite interval mapping (CIM-thick lines) analyses. The permutation-derived (n = 1000 per trait) LOD score significance criteria were 3.4, 3.2 (horizontal thin lines), and 3.8 (horizontal thick lines), respectively. For the protein QTL plot, the effects of the closest dominant RAPD marker OPAW13a and closest flanking SSR markers (Satt496 and Satt239) are indicated.
