Abstract:
The reported variation in the reaction of wild Lactuca species to pathogens and pests is summarized, including viral pathogens (e.g. Lettuce mosaic virus - LMV, Mirafiori lettuce virus/Lettuce big vein virus - LBVV, Cucumber mosaic virus - CMV), bacterial pathogens (corky root - Rhizomonas suberifaciens, bacterial leaf spot -H Xanthomonas campestris pv. vitians), oomycete and fungal pathogens (downy mildew - Bremia lactucae, powdery mildew -Golovinomyces cichoracearum, anthracnose - Microdochium panattoniana, stemphylium leaf spot - Stemphylium spp., sclerotinia drop NDASH Sclerotinia spp., verticillium wilt NDASH Verticillium dahliae, fusarium wilt - Fusarium spp., pythium wilt - Pythium tracheiphylum), nematodes (potato cyst nematode - Globodera rostochiensis, root-knot nematode - Meloidogyne spp., incognita, hapla, javanica, enterolobii), insects and mites (the green lettuce aphid - Nasonovia ribisnigri, the green peach aphid - Myzus persicae, the potato aphid - Macrosiphum euphorbiae, leafminer - Liriomyza spp.). The approaches used to exploit wild Lactuca spp. in lettuce breeding are discussed and known examples of lettuce cultivars with traits derived from wild Lactuca spp. are described.
