The resistance of 4 cotton, 2 sesame, and 6 flax cultivars to the root-knot nematodes Meloidogyne arenaria (Ma), M. incognita race 1 (Mil) and/or M. javanica (Mj) was determined in green house studies. The results showed that the cotton cvs Giza 77, Giza 85, Giza 88, Giza 89 and sesame cvs Shandwil 1 and Toshka 1 were resistant (R) to the tested nematode species. On the other hand, six flax cultivars were tested, among them Giza 1 and Giza 5 were susceptible (S) to all the tested nematode species; Giza 6 was susceptible to Ma and Mj, while Sakha 1 was susceptible to Ma only. Giza 6 was highly susceptible (HS) to Mj only whereas Sakha 1 was highly susceptible to Mi and Mj. The flax cultuvars Giza 7 and Giza 8 were susceptible to Ma and Mi while these were moderately susceptible (MS) to Mj only. In three separate experiments the response of 4 banana cultivars (Baladi, Grand Naine, Magraby and Williams), 3 peach rootstocks (Bitter almond, Baladi, and Nemaguard), and 6 ornamental palm trees (California Washington palm, Mexican Washington, Canary date palm, Queen palm, Common palmetto, and Date palm) were tested for resistance to Mi1 and Mj. The banana and peach rootstock Bitter almond were highly susceptible to Mil and Mj. Baladi peach rootstock was highly susceptible to Mj. but resistant to Mil, whereas Nemaguard rootstock was resistant to both Mil and Mj. The tested palm trees viz., date palm, California and Mexican Washington palms were susceptible to Mil and Mj. whereas Canary date palm was moderately susceptible to both nematode species. The Queen palm was susceptible to Mil but moderately resistant to Mj.
