Fig. 5. Comparisons between observed grain yields in barley and those predicted by the two models, QTL-BL and SYP-BL (redrawn from Yin et al., 2000a). Because the denso gene affected most model input traits, QTL-BL predicted two clusters in yields that match the segregation of the gene (the dwarf recombinant inbred lines had higher yields than the tall lines).
