Abstract

Six tomato cultivars Moneymaker, Beefsteak, Roma, Summertaste, Mini Roma and Smallfry were tested for their
susceptibility to root- knot nematodes at inoculum levels of 200, 400, 600 Juveniles (J2) per pot. All were found to be
susceptible to varying degrees as egg masses were present in all with Moneymaker and Roma being the most susceptible
and Mini Roma, the least susceptible. The inoculum levels had a significant effect (p<0.05) on the number of galls and
plant weights. The gall numbers and plant weights was negatively correlated, with the highest gall numbers and lowest
plant weights recorded at the highest inoculum level in all cultivars except in Mini Roma in which there was little
variation in gall numbers and plant weights.
