Two tomato (Lycopersicon esculentum Mill.) cultivars, Bonny Best and Immur Prior Beta, and their reciprocal hybrids were grown in the greenhouse to investigate the effects of multipaternal pollination on percentage fruit set, fruit weight and the leaf character ratio of the progeny seedlings. Mixed pollen did not increase the percentage fruit set significantly, but increased the fruit weight for the true breeding cultivars. The seedling leaf shape in the progenies from the self-, cross- and mixed-pollinations indicated that a plant favors its own genotype pollen when there is a mixture of genotypes present at the time of pollination.
