Decrease in Globodera rostochiensis (Wollenweber) (Nematode: Heteroderidae) population density on resistant tomato cultivars in greenhouse trials

We developed polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) markers for the potato cyst nematode (PCN) resistance gene Hero A in tomato. Using these PCR-RFLP markers, we evaluated the presence of Hero A in tomato cultivars. All cultivars displayed complete concordance between their PCN phenotype and the genotype as determined by PCR-RFLP. We confirmed that PCN-resistant tomato cultivars in Japan contained the Hero A gene, whereas susceptible cultivars did not. PCN is a highly important quarantine pest, and the PCR-RFLP markers for Hero A provide a means of testing for resistance without the need to use live nematodes. Nematol. Res. ( ), -

Tobacco cyst nematode (TCN) Globodera tabacum is able to develop and reproduce on tomato plants and eggplants. As a consequence, plants with a heavy infestation show stunted growth. The most effective and environmentally benign method for managing plant nematodes is through exploitation of host resistance. However, comparatively little information is available on the relative rates of reproduction of TCN on different tomato cultivars and resistance to TCN has not been studied in detail. In the present study, we compared the response of several tomato cultivars to inoculation with TCN in order to identify those with greatest resistance. As a result, five new TCN-resistant tomato cultivars, 'Doctor-K', 'Sugar-Lamp' 'Carol-', 'Carol-Queen', and 'Chelsea-mini', were identified. Nematol. Res. ( ), -( ).
