Fig. 1. A map of a portion of the white clover genome, indicating the positions of 23 QTLs for seed yield and its component traits. Box-bars indicate the genome region within one LOD unit of the peak LOD score, extending lines indicate genome region with LOD scores within 2 LOD units of the peak. The QTL names are to the left of each boxed bar. Only the nine linkage groups with seed production QTLs are depicted; in this experiment no QTLs were detected on the other seven linkage groups.
