ABSTRACT:

The Mi gene is a single dominant gene that confersresistance to M. incognita, M. javanica, and M. arenaria. It is locatednear the centromere of chromosome 6. Bailey (1940) provided an earlyreport of the wild Tomato species Solanumperuvianum as a source of resistance to root-knot nematodes. Due toreproductive incompatibilities between the Solanum lycopersicum and S.peruvianum, embryos resulting from crosses do not reach maturity. Consequently, techniques for embryo rescue techniques were developed in whichimmature embryos are dissected from seed and cultured axenically. Thetechnique appears to have been first used to transfer the Mi gene from wildTomato into commercial cultivars by Smith (1944) in crossing Solanum lycopersicum var.
