This article presents the results of a comprehensive study on Rosa acicularis Lindl., Rosa laxa Retz., and Rosa spinosissima L. growing in the sharply continental climate of the Kazakhstan Altai under diverse ecological and phytocenotic conditions. All three wild rose species show notable ecological plasticity, allowing them to thrive in heterogeneous environments. A total of 41 populations were recorded: 12 of R. acicularis, 13 of R. laxa, and 16 of R. spinosissima, with vertical distribution ranging from 404 to 1837 m a.s.l. Nine populations where each species dominates its plant community were selected as model sites to assess ecological, biological, and economic traits. For each population, the floristic composition and structure were described, and morphometric, resource, and physiological indicators were evaluated. Significant phenotypic variation was noted in plant height, bush diameter, leaf traits, and fruit morphology and taste. Under natural conditions, industrial thickets are mainly formed by R. laxa in the Southern Altai and by R. spinosissima in the Southwestern Altai due to their wide distribution and high plant density. Fruit weight ranged from 2.23 to 2.47 g (R. acicularis), 2.28 to 2.68 g (R. laxa), and 2.17 to 2.55 g (R. spinosissima), values generally lower than those previously reported. Based on coefficients of variation for intra-population diversity in morphological and quantitative traits, several promising populations were identified. These populations hold potential for selecting valuable forms for breeding programs and for establishing a regionally adapted gene pool.
