Investigation of the post-cryogenic regeneration ability of potato varieties under different cultivation conditions by E. S. Bespalova, Yu. V. Ukhatova, N. N. Volkova, E. V. Oves, N. A. Gaitova, T. A. Gavrilenko

“…The factor “prolonged dark incubation of explants” did not have a significant effect on the frequency of post-cryogenic regeneration of the studied varieties except for one variety (Krepysh), for which a significant increase in the regeneration rate was observed for the shoot tips cultivated in the darkness compared to the cultivation under the photoperiod 16/8 hours (light/darkness). The frequency of post-cryogenic regeneration of shoot tips was higher than that of the axillary buds for all varieties; however, these differences were significant (p < 0.05) only in two cases: for the variety Udacha (a photoperiod of 16/8 hours) and for the variety Krepysh (the dark incubation). …”
