INSTANCES of male sterility resulting from the interaction between the cytoplasm of one
species and the nuclear contents of others have been reported in the genus Begonia
by Villerts (1942, quoted by Edwardson, 1956), in Nicotiana by Clayton (1950) and
also by Koopmans (1955) in interspecific crosses between Solanum chacoense and
S. rybinii. In the interspecific and intergeneric crosses studied by the author, staminal
sterility appeared characteristically in .certain combinations when S. spontaneum was
the pistillate parent, confirming the findings of Raghavan (1951). In all cases, reciprocal crosses gave fertile plants only.
