Abstract: In a survey of nematodes associated with potato conducted in six major potaro- producing regions of Saudi Arabia from 1989 to 1991, following genera in descending order of frequency were found: Aphelenchus (40%) Okyiencht-(28%). Tylenchorhynchus(20%),Mebittogynt (19%).Aphebnthoidet lyttnchuisi. (10%),Subanguina (6%), Tnchodarus (5%). fratylcnchus and Heltcntfenehzx (2%), MacMpasihohia (0.7%) and ParaiylcHchus and Cocoptmrvs if (1%). Distribution ircrjuency and population density of these genera varied among the six regions - Hail and Tsthyk wcie ihe lowest Wiih respect IO diversity and density, Gassim and Riyadh were moderate ami Hofuf and Najran were itac highest. Prominence- values of the jssoriatcd ncrnstixles indicated that Mclaidagyne $pp (mainly Mjavanica) were, by far the must prominent plant-parasitic nematodes in Saudi potato fields, followed by 7>tenckorhynchus spp., and then by Ditytenchus spp (mainly D. destructor).
