Summary

Ploidy stability in dihaploid cultivars of Solanum tuberosum and in wild genotypes, regenerated from cryopreserved shoot-tips, was assessed by flow cytometry. Frozen shoot-tips were compared with explants of potato subjected to other in vitro manipulations. The frequency of polyploidization was minimal in plants regenerated from cryopreservation as compared with those derived from leaf explants and protoplasts. Cryopreservation does not appear to induce ploidy changes in sensitive dihaploids of S. tuberosum.
