Fusarium wilt
The CLN3241-coded F 7:8 lines and check differentials were assessed in separate trials for resistance to race 1 and race 2 of F. oxysporum f. sp. lycopersici according to Sheu and Wang (2006). Checks included Bonny Best (susceptible), UC 82-L (race 1 resistance conferred by I gene) and Florida MH-1 (I gene and race 2 resistance conferred by I-2 gene). AVRDC isolates Fol-11A (race 1) and Fol-34-1 (race 2) were used for inoculation. The inoculum was prepared
by blending 7-day-old potato dextrose agar plates with distilled water (125 mL per plate). Two- week-old tomato seedlings were uprooted and root-dipped in the fungal culture slurry for 5 min and then transplanted to trays containing fresh potting mixture. The inoculated plants were kept in the greenhouse with the mean temperature above 25 ◦C. Plots of entries and checks included 12 plants and plots were arranged in a RCBD with three replications. Each plant was visually scored three weeks after inoculation according to the following scale, where 0 = healthy; 1 = slight vas- cular discoloration; 2 = severe vascular discoloration usually with stunting; 3 = plant wilted beyond recovery or dead.
