The CLF (Corynespora Leaf Fall) disease caused by the necrotrophic fungus Corynespora cassiicola has gained increasing importance in most areas of rubber cultivation in Asia and West Africa. To avoid developing susceptible varieties, we want to develop a selection program based on a better understanding of the interaction between the parasite and the plant. In a previous study, we purifieda secreted toxin, cassiicolin, from the culture filtrate of an aggressive C. cassicolastrain (CCP, from Philippines). The amino acid sequence and three-dimensional structure of the toxin were described previously.The application of purified cassiicolin or conidial suspension inoculation from the CCP isolate resulted in the same visual symptoms with similar sensitivity profiles, suggesting that cassiicolin is an important effector of C. cassiicola pathogenicity (Barthe et al. , 2007; Breton, Sanier, & d'Auzac, 2000; Deon et al., 2012a; Deon et al., 2014; Deon et al., 20 I 2b ). The construction of genetic linkage maps for cultivated rubber clones (Hevea brasiliensis) has and continues to be an important research goal to facilitate quantitative trait locus (QTL) analysis for use in a marker-assisted selection in breeding (Le Guen et al., 2011; Lespinasse et al., 2000; Pootakham et al., 2015; Prapan et al., 2006; Souza et al., 2013). Our recently published maps were constructed from the cross of cultivated rubber clones, in which isozyme biochemical markers and molecular markers (RFLP, RAPD, AFLP or SSR or SNP) were used. The objective of the present study was to explore a new genetic map in order to identify QTLs of sensibility/tolerance to C. cassiicola secreted effectors. The FI progenies derived from the cross of two cultivated clones PB260 x RR1M600, planted in two trials in Ivory Coast, were genotyped using SSR markers only. Three saturated genetic maps were constructed: one for each site and one consensus map. Eighteen linkage groups corresponding to the eighteen chromosomes of
