Growth and resistance response of tomato genotypes to root-knot nematode, Meloidogyne incognita
Keywords:Root-knot nematode, tomato
AbstractTwenty-five exotic accessions belonging to Solanum lycopersicum and six commercial cultivars of tomato were evaluated to identify the source of resistance against root-knot nematode, Meloidogyne incognita and effect of nematodes on plant growth characteristics. Infection of root-knot nematode, M. incognita resulted in reduction in plant growth characteristics and increase in root damage in all the accessions. Two accessions, EC631364 and EC620395 were found susceptible and remaining accessions were found highly susceptible. Therefore, none of the germplasm screened in the present study is useful as M. incognita â€”resistant parental material in tomato breeding programs.
