First Report of Columbia Root-Knot Nematode (\u3ci\u3eMeloidogyne chitwoodi\u3c/i\u3e) in Potato in Turkey

Columbia root-knot nematode, Meloidogyne chitwoodi Golden et al., was identified from potatoes, Solanum tuberosum L., collected from Nigde Province, Turkey in September 2006. Seed potatoes are the most likely source for this introduction. The nematode is currently found to be infecting potatoes grown in the Netherlands, Portugal, Belgium, Germany, the United States, Mexico, South Africa, and Argentina. M. chitwoodi acquired a quarantine status in Europe (1) because of its potential to become established worldwide and its high damage probability. Some countries prohibit import of both seed and table stock potatoes originating in states known to harbor M. chitwoodi. Lesions on the potatoes had discrete brown coloration with white central spots in the outer 1 cm of the tuber flesh

IDENTIFICATION AND GENETIC DIVERSITY OF MELOIDOGYNE CHITWOODI IN POTATO PRODUCTION AREAS OF TURKEY

WOS: 000274364600006Root-knot nematodes (Meloidogyne spp.) were first detected in Turkey during regional nematode surveys of potato fields of Nigde province. Twelve populations of Meloidogyne were collected and identified based on morphological characteristics as well as molecular methods including species-specific primers, confirming that all twelve populations were M. chitwoodi. To estimate genetic relationships among these twelve populations, random amplified polymorphic DNA (RAPD) analysis was done and the results were subjected to UPGM analysis. Analysis of 394 RAPD markers resulted in a similarity coefficient, ranging between 0.64 and 0.81 with a mean similarity of 0.72. The populations Mc3 and Mc4 displayed the greatest genetic similarity (81%). The lowest level of similarity (65%) was observed between Mc9 and Mc7. The large genetic variation among the M. chitwoodi populations indicates that multiple sources of inoculum might have been introduced to the region or that the populations formerly existed in these potato growing areas of Turkey
