The application of an excised root assay for the determination of susceptibility or resistance to root-knot nematodes (Meloidogyne spp. Goeldi) in potatoes (Solanum spp. L.)
Excised roots of six potato selections were challenged with egg inoculum of fourMeloidogyne species:M. chitwoodi, M. javanica, M. incognita, andM. hapla. The dual cultures were established under aseptic condition...
