The viability of pollen of 5 collectible varieties of Russian plum of the Pushkinskiye and Pavlovskiye VIR Laboratories SPB before and after cryopreservation was studied. It was found that a significant factor for the level of pollen viability is “variety” (p=0.07), the factors “cryopreservation” (p=0.457), “year” (p=0.221), as well as the interaction of the factors “variety× cryopreservation” (p=0.172), were not significant at the p<0.05 level of significance. For long-term storage of Russian plum pollen in liquid nitrogen, the year of pollen collection is not a significant factor. For most genotypes, no negative impact of cryoсonservation on pollen viability was revealed. The varieties ‘Aureus’, 'Podarok Sankt-Peterburgu’ and ‘Exotica’ after cryopreservation for 1 year showed a tendency to increase the pollen viability indicators.
