Abstract The resistance of Lycopersicon hidutum LYC4 to Botrytis cinerea was evaluated by inoculating spore suspension to seedlings，and leaf，stem，fruit segments．The results showed that the disease index was 0 in both seedlings and detached-leaves，the relative stem infection rate and fruit rot expansion rate were 0 and 5.7 %，respectively．For this reason，the L. hirdutum LYC4 is considered to be highly resistant to tomato gray mold.
