Abstract :Pepper (Capsicum annuum L.) (Solanales: Solanaceae) is one of the most important agricultural products consumed in the world. Root-knot nematodes (RKNs (Meloidogyne spp.)) are major pests that occur dramatically damage on pepper. However, the management of RKNs has some difficulties and one of the most effective methods is using resistant cultivars in infested areas. In this study, the efficiency of molecular markers linked to Me1 and N genes was investigated. The study was conducted in laboratory and under controlled conditions at Akdeniz University Faculty of Agriculture, Department of Plant Protection Nematology Laboratory in 2022. Pepper genotypes belonging to two main varieties (Charleston pepper and Bell pepper) were tested against S6 isolate of Meloidogyne incognita (Kofoid & White, 1919) Chitwood 1949 (Tylenchida: Heteroderidae), and screened with molecular markers. As a result, molecular markers linked to two genes gave compatible results with pathologic tests. These markers can be successfully used for marker assisted selection in pepper genotypes.
