Fig. 1. QTL plots for the 14 agronomic traits in common bean and the alignment of linkage groups from the current map (linkage groups G1–G12), the previous map that was developed at the University of Florida (linkage groups A–K; Vallejos et al., 1992) and the core map of common bean (B2–B11; Freyre et al., 1998). The maps were drawn on the same scale. No common loci were found between linkage groups G8 or G12 of the current map with linkage groups H and L of the University of Florida map. Vertical bars indicate the location of QTL for a given trait with a LOD value >2.5 in the mean environment (see Table 6). Map units are in centimorgans. Loci that deviated from Mendelian segregation ratio are indicated with *. Y = seed yield; DF = days to flowering; DM = days to maturity; PH = plant height; TN = total nodes; TB = total branches; Ag = branch angle; HD = hypocotyl diameter; Lg = lodging; HI = harvest index; UP = upper pods; PPP = pods per plant; SPP = seeds per pod; SW = 100-seed weight; GH = growth habit.
