Abstract
Ploidy stability in dihaploid cultivars of Solanum tuberosum and in wi ld genotypes, regenerated from cryopreserved shoot-tips, was assessed by flow cytometry. Frozen shoot-tips were compared with explants of po tato subjected to other in vitro manipulations. The frequency of polyp loidization was minimal in plants regenerated from cryopreservation as compared with those derived from leaf explants and protoplasts. Cryop reservation does not appear to induce ploidy changes in sensitive diha ploids of S. tuberosum.
