| Abstract: | Summary Fusions of protoplasts from Nicotiana langsdorffii and Nicotiana glauca were induced using polyethylene glycol. Parasexual hybrid colonies were selected for their ability to grow without growth substances. Hybrid plants, regenerated after grafting, were all tumorous and exhibited morphological and chromosome number variations. Out of 48 colonies selected in vitro only 6 regenerated flowering plants. Two of these plants had 42 chromosomes and were morphologically identical to the sexual amphidiploid Nicotiana glaucaxlangsdorffii. |
