It is known to all that cytogenetical studies on the species and their hybrids in the section Tuberarium of the genus Solanum offer many important theoretical grounds not only to elucidation of evolutional relationships in the genus but also to breeding works of potato by using its related species with economically valuable characters. From this point of view, our information has to some extent been being advanced by earlier workers. View seems still to be divergent, however, on genome constitution and basic number in the genus, because the cytological behavior is very singular. The triploid species and hybrids are a favorable subject for investigating such problems, which have already been studied by MUNTZING (1933), OPPENHEIMER (1933), EMME (1936), PROPACH (1937), LAMM (1945), KOOPMANS (1951), OKUNO (1951) and PRAKKEN and SWAMINATHAN (1952) etc. In order to research accurately inter-relationships between the meiotic behavior and the genomic affinity, the present author has dealt with the F_1 hybrid from the cross S. longipedicellatum×S. Schickii and its parent species as the materials in this study, and the results will be given in this paper.
