Twenty seven leguminous cultivars were tested for their host response to Meloidogyne javanica. The nematode species succeeded in developing and multiplying on almost all the tested crops. According to rating scale based on nematode reproduction, Lencoln and Victory cultivars of pea were considered as highly susceptible hosts with (Rf) values 36.5 and 25.68 folds, respectively. While Maser-1 cultivar of broad bean and Bronco, Exira, Giza-6, Polista and Savana cultivars of common bean were classified as moderately susceptible hosts to
nematode infection with (Rf) values ranged between 5.27 and 14.21 folds. Thirteen other tested cultivars were found least susceptible with (Rf) values ranged between 1.13 and 4.86 folds. On the other hand, M. javanica failed to reproduce and multiple on Giza-2 and Giza-30 of fenugreek and Giza-1 and Giza-2 of lupine which were ranked as highly resistant hosts with (Rf) values 0.12, 0.33, 0.19 and 0.42 folds, respectively, whereas Giza-843 and Giza-51 of broad bean and lentil were regarded as resistant hosts to nematode infection with (Rf) values 0.59 and 0.80 folds, respectively.
