Abstract: All tested plants of 11 accessions of the typical form of Lycopersicon peruvianum and 11 of its variety dentatum were found to be self-incompatible. Reactions tested extensively in one collection conformed exactly to the Nicotiana scheme. In addition, the other available species of the green-fruited subgenus Eriopersicon—L. peruvianum var. humifusum, L. glandulosum, and L. hirsutum—are self-incompatible, the reaction in the three species seeming to be as strong in their native habitat as in cultures in California. The species of the red-fruited subgenus Eulycopersicon are self-fertile, as is also L. hirsutum f. glabratum.
