Abstract
Three field trials were conducted to determine response of Meloidogyne javanica to tomato cultivars containing the Mi gene for resistance. Trials were conducted in the Spring and Fall of 1997 and Spring of 1998 on the same site. Tomatoes were grown on polyethylene mulch in a site initially treated with methyl bromide and then inoculated with M. javanica via drip tubing. Cultivars with the Mi gene were ;PSR 8991994; and ;Sanibel; while susceptible cultivars were ;Colonial; and ;Agriset 761;. Fruit weights were only significantly increased in one test by using resistant tomato. However root galling was greatly reduced with resistant cultivar in the three tests. Population densities of second-stage juveniles were low in soil samples collected from the resistant cultivar in the one test where data were collected. In the three successive crops no evidence of resistance-breaking biotypes of M. javanica was observed.
