In a pot experiment certain cultivare of winter and sununer
field crops were evaluated for their resistance to some common
neratode genera in Egypt. Results indicated that in winter crops
wheat cvs. Giza 157 Giza 155 and Chenah 70; barley cv. Giza
121; and clover y. Meskawy were resistant to Pratylenchus zeae.
Faba bean cv. Romy was resistant to tieloidogyne avanica. On
the contrary1 f aba bean, cultivar Giza 1; wheat ave. Giza 157,
F Giza 156 and Chenab 70; and Egyptain lupin cv. Balady were highly
susceptible to K. javanica. Wheat cv. Giza 157; faba bean cvs.
Giza 1 and Giza 3 were highly susceptible to 14. incognita race
3. Faba bean (Introduction 155), flax cv. Rauliuns; and fenugreek
cv. Balady were highly susceptible to !. zeae. The other hosted
cultivare of winter field crops varied in their reaction to root—
knot and lesion nematodes. Root-knot and lesion nematodes signif j
cantly affected dry weights of the tested winter field crops.
In summer field crops, seasame cv. Giza 23 was resistant to M.
javanica and M. incognita race 3, but it was susceptible to P.
zeae. Cotton cvs. Giza 70 and Giza 74 were resistant to M.
javanica,, but they were susceptible to M. incognita race 3 and
P. zeae. On the contrary, soybean cv. Williams was resistant
to P. zeae but it was susctible to the two species of root—
