Inheritance of tomato resistance to Colletotrichum dematium
HortScience 25 (5), 562-564
Abstract: A tomato (Lycopersicon esculentum Mill.) breeding line (81B416) with' resistance to anthracnose caused by Colletotrichum dematium was crossed to three susceptible genotypes. Parental, F₁, F₂, and backcross populations were analyzed in the cross with 'US28', while parental, F₁, and F₂ populations were tested in crosses of 81B416 with 'US141' and 81B9. Inheritance of resistance was primarily additive, but 3- and 6-factor scaling tests indicated the presence of dominance and epistatic effects. The average broad-sense heritability estimate was 0.57; narrow-sense heritability was estimated at 0.42.
