title: Mentor pollen effects on gametophytic incompatibility in Nicotiana, Oenothera and Lycopersicum.
abstract: Attempts were made, through mentor pollen techniques, to overcome self-incompatibility in species belonging to the genera Nicotiana and Oenothera and in a hybrid of Lycopersicum, which are characterized by a gametophytic system of incompatibility. While radiation-killed incompatible pollen did not generate mentor effects in any of the material tested, radiation-killed compatible pollen was found to promote a high level of illegitimate fertilizations by incompatible pollen in N. alata. No evidence was obtained that radiation-killed compatible pollen could induce mentor effects in strictly self-incompatible clones of O. organensis and of the interspecific hybrid L. esculentum x L. peruvianum.
