Abstract: Diallel matings of F1 plants from intraspecific (Capsicum cardenasii) and interspecific (C. pubescens × C. cardenasii) crosses indicated a gametophytic system of incompatibility of the Nicotiana type in both species. Each F1 progeny, regardless of the direction of the cross, constituted four intrasterile, interfertile groups. When self-incompatible C. pubescens or C. cardenasii plants were crossed with self-compatible C. pubescens, all F1 and F2 plants were self-compatible. F1 plants accepted pollen readily from either parent. In contrast to Nicotiana, however, the self-incompatible strains accepted pollen readily from self-compatible plants.
