Abstract: Fourteen imported potato cultivars (Agria,Ajax,Ariane, Atica, Cozmos, Draga, Escort, Ilona, Lesita, Mirka, Mondial, Morene, Planta and Spunta ), grown in Saudi potato fields, were evaluated for their host suitability to Meloidogyne javanica in greenhouse tests. The standards and parameters adopted by the International Meloidogyne Project were followed. All tested cultivars were found to be susceptible and good hosts to M. javanica. Values of gall index GI ( 0 - 5 ) ranged from 3.3 for cv. Planta to 5.0 for cv. Agria, Mondial and Morene. Reproduction factor RF ranged from 4.1 for cv. Lesita to 94.7 for cvs. Mondial. Although all cultivars were designated as susceptible, they differed (P0.05) with respect to GI, RF and number of eggs per gram fresh root. Development or introduction of resistant cultivars is essential for the management of M. javanica in our potato fields
