REACTIONS OF SOME GRAMINEOUS AND LEGUMINOUS PLANT CULTIVARS TO MELOIDOGYNE INCOGNITA AND M. JAVANICA

Abstract

The reactions of 6 corn, 8 whead and 24 leguminous plant cultivars to Meloidogyne incognita race 1 and M. javanica were studied in pot experiments. All corn cultivars tested were susceptible to both nematodes except that cv. Cairo 1 was moderately resistant to M. incognita and cv. TH 310 was moderately resistant to M. javanica. Wheat cvs Giza 160, Sakha 8, Sakha 61, Sakha 69 and Stork were resistant, whereas cvs Giza 157 and Land Race were susceptible or moderately susceptible to both nematode species. Most of the leguminous cultivars tested were susceptible whereas alfalfa cv. Cuf 101 was resistant to the root-knot nematodes. Lupin cvs Giza 1 and Giza 2 were resistant to M. javanica and peanut cv. Giza 4 was resistant to M. incognita.
