The southern region of Kazakhstan represents the northernmost boundary of the natural habitat of five wild almond species, among which Amygdalus communis L. is of particular interest due to a range of favorable traits for use in breeding programs and cultivation in the region. The current distribution range of common almond growth was clarified using GPS to determine precise coordinates, and a schematic map was developed. Monitoring revealed a significant reduction in population size. In the surveyed areas, 54 trees were selected and described. Seed material was collected from 34 genotypes and characterized according to a descriptor. Genotypes A3, A8, and A15 were identified as having favorable trait combinations. To restore populations and preserve the gene pool of Amygdalus communis L., a method of clonal micropropagation was employed. The composition of the nutrient medium was optimized for establishment, multiplication, and rhizogenesis. It was determined that Murashige and Skoog (MS) medium without phytohormones is effective for in vitro establishment (70% regeneration rate). For multiplication, MS medium with 0.5 mg/L BAP (6-benzylaminopurine) was used (with a multiplication rate of 3.5 per explant). For rhizogenesis, MS medium with 0.5 mg/L BAP, 0.02 mg/L gibberellic acid (GA), and 0.1 mg/L IBA (indole-3-butyric acid) was used. A total of 340 clonal Amygdalus communis L. plants with closed root systems were grown for field collection. The research results can be applied for the restoration, propagation, and conservation of populations both in vitro and in situ, as well as for the inclusion of selected high-performing genotypes in breeding programs.
