| Abstract | ||||
| Ten Cruciferae crops species were evaluated for their host’s response to root-knot nematode,Meloidogyne javanica. The nematode succeeded in developing and multiplying on all most tested cultivars (cvs.). The ten plant species were divided by their degree of susceptibility to root-knot nematode,Meloidogyne javanica as follows: Radish Baladi cv., Cabbage Brunswick cv. and Cabbage Japanese cv. were very resistant host to nematode infection. The calculated values of the numbers of galls per root and rates of nematode reproduction on such cultivars were (24.50–0.15), (9.00 –0.04) and (6.25–0.02) respectively. While Cabbage Sabeini cv., Cauliflower Sultani cv. and Cabbage Dutch cv. were slightly resistant hosts to nematode infection. The calculated values of the numbers of galls per root and rates of nematode reproduction on such cultivars recorded moderate values were 63.75–0.58, 62.25–0.02, and 61.75–0.76 respectively. Turnip Baladi cv., Turnip Japanese cv., Red Radish cv. and Cauliflower Chinese cv. were susceptible hosts to nematode infection, their calculated values of the numbers of galls per root and rates of nematode reproduction on such cultivars were 290.75–9.29, 232.75–4.92, 169.50–4.29 and 120.75–0.29, respectively. | ||||
