Abstract: A comprehensive study was conducted to develop an effective protocol for the clonal micropropagation and subsequent acclimatization of three mint (Mentha) cultivars: ‘Pamyati Kirichenko’, ‘Botanicheskaya’, and ‘Serebryanoe Chudo’. This research investigated the influence of nutrient Murashige–Skoog medium composition with the addition of growth regulators (BAP/NAA) on in vitro morphogenesis, as well as the impact of two acclimatization methods to in vivo conditions (direct field planting and a two-stage acclimatization approach) on field performance, yield, and essential oil composition in three mint cultivars. The results revealed a distinct cultivar-specific response. The ‘Pamyati Kirichenko’ and ‘Botanicheskaya’ cultivars showed high efficiency on the BAP/NAA medium and good survival rates with both acclimatization methods. In contrast, the ‘Serebryanoe Chudo’ cultivar exhibited pronounced sensitivity to the medium with growth regulators and a low survival rate upon direct planting (40.5%). The two-stage acclimatization method proved critically important for this cultivar, enabling an increase in survival to 68%, as well as improvements in yield, essential oil output, and the restoration of its cultivar-specific linalool profile (59.5% linalool). It was established that, for cost-effective production, an individual selection of technological parameters for each genotype is necessary at all stages of microclonal propagation.
