is the one of the most frost-tolerant species in the genera, used as a rootstock for colder regions. Natural populations of have a fragmented character of distribution in the Northwestern Caucasus, one of the coldest regions of cultivation. To predict the behavior of populations in an extreme environment, it is necessary to investigate the intraspecific genetic diversity and phenotypic variability of populations in the colder regions.

In our study, 51 commercial cultivars of , 3 accessions of and 57 accessions from six geographically distant populations were investigated using 19 microsatellite and 10 inter simple sequence repeat (ISSR) markers. After STRUCTURE analysis, the single accessions of were allocated to three genetic clusters.

Both stresses cause osmotic changes in the cells of the tea plant by decreasing their water potential. To develop cultivars that are tolerant to both stresses, it is essential to understand the genetic responses of tea plant to these two stresses, particularly in terms of the genes involved.

The acclimatization of tea plant from tropical to temperate climate regions resulted in unique germplasm in the North-Western Caucasus with extremely frost-tolerant genotypes.
