Abstract

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 (L. 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 C. 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.
