Various methods of screening for resistance to root-knot nematodes were compared and evaluated. Seedling populations of Solanum spp., grown in clay pots and plastic tubes with silver sand and inoculated with juveniles of Meloidogyne chitwoodi and M. hapla, showed large differences in the number of egg masses on roots 7 weeks after inoculation. The differences were reproducible when re-testing was done with cuttings and plants from tubers. No resistance to Meloidogyne spp. was observed with ten potato cultivars when grown in clay pots, plastic tobes or closed containers. Plants from tubers in growth pouches developed a large two-dimensional root system, and after inoculation with juveniles the infection process could be observed over 8 weeks. A method of infecting potato tuber tissue with Meloidogyne is described, using tuber slices in Petri dishes as a potential screening test for tuber resistance. [ABSTRACT FROM AUTHOR] |
