Response of Tomato Cultigens to Meloidogyne javanica and Races of Meloidogyne incognita.
Thirty-six cultigens of tomato were evaluated for resistance against Meloidogyne javanica and four races of M. incognita with standards and parameters adopted by the International Meloidogyne Project. Most cultigens were susceptible to the nematodes, including some that were previously reported to be resistant to these nematodes. Ten accessions, namely Pusa-120, Calmart VFN, Panjab 6.NR-7, EC173898 (72T6), EC173897 (Cal-Mart), EC173896 (Kewalo), CLN363BCF-167-1-0, CLN363BCF-190-1-0, CLN363BCF-344-0-0, and CLN299BCF-4-1-4-1-1-0, were immune to all test nematodes. VFN-Bush and VFN-8 were resistant to all four races of M. incognita and immune to M. javanica. Three cultivars (Pant-T, Money Maker, and Pelican) exhibited a degree of race-specific resistance to M. incognita. Pant-T and Money Maker were hypersusceptible to race 1 and race 4 of M. incognita, respectively, but were susceptible to other races. Pelican was tolerant to M. incognita race 3 but resistant to the other races.
