Occurrence of resistance-breaking populations of root-knot nematodes on tomato in Greece
European Journal of Plant Pathology 113 (1), 101-105
Abstract: Nine populations of Meloidogyne spp. from Greece have been identified as M. javanica or M. incognita using either isozyme phenotypes or the sequence characterized amplified region-polymerase chain reaction (SCAR-PCR) technique. Virulence against the Mi resistance gene was assayed by pot experiments in controlled conditions and revealed the ability of five populations of M. javanica and one population of M. incognita to reproduce on tomato cultivars containing that gene. A resistance-breaking population of M. incognita is reported for the first time in the country; the M. javanica populations constitute new records for the Greek mainland.
