Fig. 1. Summary and comparison of plant height, growth habit, and flowering QTLs detected in the full-sib Leymus triticoides x (L. triticoides x L. cinereus) TTC1 and TTC2 families based on 2002, 2003, 2004, and average measurements. The approximate location of QTLeffects (LOD 3.3), corresponding to a genome-wide P 0.05 signficance level, detected using a restricted multiple QTL model (rMQM) are indicated by black or white bars for each trait x year. The updated molecular genetic linkage maps include 488 homologous AFLP markers and mapped in both TTC1 and TTC2 families (Wu et al., 2003), 50 anchor markers (larger bold marker text) mapped in TTC1 and/or TTC2 families (Wu et al., 2003), and 17 additional anchor markers (larger bold italic marker text) mapped in the TTC1 and/or TTC2 families. Annotation next to each anchor marker indicate homoeologous groups of barley (H), wheat (ABD), cereal rye (R), and in parentheses oat chromosome designations.
