| Outline of Final Research Achievements |
We aimed to develop a new CMS line of eggplant using the cytoplasm of Solanum macrocarpon. Since F1 of S. macrocarpon and eggplant is sterile, in this study, F1 was treated with colchicine to produce the amphidiploid, and then the amphidiploid was self-propagated to produce self-fertilized seedlings of the amphidiploid. Using these seedlings from the amphidiploid, we aimed to develop a male sterile line with the cytoplasm of S. macrocarpon. As a result, the cytoplasmic replacement line of eggplant using the cytoplasm of S. macrocarpon has male sterility without anther dehiscence, and the development of a new male sterility line of eggplant can be expected in the future.
