Abstract

Twenty five isolates of Meloidogyne collected in two Moroccan vegetables growing areas (Oualidia and Souss-Massa) were identified by esterase profiles. 80-82 % of isolates were from M. javanica and 18-20 % were from M. incognita. The former species was found on crops grown in plastic greenhouses, as well as on crops grown in open field, mainly tomato, eggplant, melon, and banana, and on weeds. M. incognita was found on sweet pepper and carnation grown under plastic greenhouses and on tomato grown in open field. Of the twenty isolates of Meloidogyne tested, nine tomato resistance breaking isolates of M. javanica were found virulent on the cv. Darus, and six of them were virulent on the cv. VFN8. Additional sources of resistance in Lycopersicon peruvianum P1270435 and in L. peruvianum var. glandulosum PI126443 were resistant to some extent to the tested M. javanica isolates.
