N2  - This work was done during the period from 2011-2015 to produce cucumber inbred lines possessing high level of resistance to root- knot nematodes, Meloidogyne spp. combined with highly commercial acceptable characters. This study was divided into three phases; The first one was performed under micro plot and field conditions extending for five successive generations as a complementary phase to a previous breeding program to satisfy the goal of this study. Evaluation for resistance was estimated based on four nematode parameters, viz., root gall index, numbers of galls, egg masses and eggs (fecundity). Results showed that level of resistance was gradually increased with the progress in the inbreeding program by selecting. The last advanced step in the breeding program yielded three inbred lines which were highly resistant to Meloidogyne spp. compared with beit alpha variety. These inbred lines are potentially promising as a good source for producing new hybrids characterized by high nematode resistance level and good yield quantity and quality. The second phase was done to evaluate the best produced inbred line against five nematode populations originated from different localities of relatively of various governorates at the different nematode levels, the results indicated that the successfulness of the breeding program. The resistant inbred line suppressed the nematode populations much more than happened by the susceptible beit alpha cultivar
