Fig. 1. Linkage map from 98 F4 derived recombinant inbred lines originated from a cross between Bunsi and Raven. Linkage groups B2, B5, B7-b and B8 correspond to the integrated map (Freyre et al., 1998) and QTL for white mold resistance were identified by composite interval mapping analysis over two years, 2001, 2002. AFLP primers used: E = EcoRI primer; M = MseI primer, followed by three selected bases and fragment size (bp). PvPr-2, Pgip, ChS, Lec-2 and Lec-3 are defense response genes mapped to the integrated bean map.
