In the 1940's the root-knot nematode resistance gene (Mi) was introgressed into the cultivated tomato from the wild species, L. peruvianum, and today it provides the only form of genetic resistance against this pathogen. We report here the construction of a high resolution RFLP map around the Mi gen

## Summary A dominant allele at the __Mi__ locus on chromosome 6 of tomato (__Lycopersicon esculentum__ Mill) confers resistance to three species of rootβknot nematodes (__Meloidogyne__). The resistance, which is associated with a localized necrotic response, was originally introduced into tomato f
The dominant gene I2 confers on tomato (Lycopersicon esculentum) resistance against the fungus Fusarium oxysporum f. sp. lycopersici race 2. A restriction fragment length polymorphism (RFLP) marker, TG105, has recently been found to be tightly linked to I2. The potential for cloning this gene by a r
