Fig. 2. Genomic localization of QTL identified for field resistance to L. maculans in DH and F2:3 Darmor x Samourai populations compared with those revealed in the Darmor-bzh x Yudal DH population (Pilet et al., 1998a) across a total of 4 yr. Resistance was assessed by the mean disease index (I) in the two crosses and the percentage of lost plants (P) in the cross Darmor-bzh x Yudal. Note: Linkage groups (LG) of genetic maps constructed from the DH Darmor-bzh x Yudal population and the DH and F2:3 Darmor x Samourai progenies were named DY, DS and DS*, respectively. Only the LG where QTL were identified are represented. Distances between markers are indicated in Kosambi cM. QTL length is the confidence interval where the likelihood of the presence of a QTL is within tenfold (1 LOD) of its maximal value
