Popis: Mi derived from Anahu and Cf-2 derived from Indian River are approximately at locations 35 and 43 on the long arm of chromosome 6 of the tomato (Lycopersicon esculentum Mill.). Ontario 7716 contains the leaf mold resistance gene Cf-11 which was derived from an aberrant plant of Mass. #2. Both Cf-2 and Cf-11 confer immunity from Cladosporium fulvum Cke. races 1 and 10. Cf-11 confers high resistance to race 6 and slight tolerance to race 12 whereas Cf-2 does not confer any resistance to these races of C. fulvum.
