Техногендiк экожүйелердегі шырғанақтың генетикалық алуандығы

   Genetic diversity is a key indicator of a species’ evolutionary development, adaptability, and long-term survival, making its conservation and study an important scientific task. Sea buckthorn (Hippophae rhamnoides L.), traditionally used for centuries and valued for its high content of bioactive compounds, is gaining increasing economic significance. This study assessed the genetic diversity of H. rhamnoides in technogenic zones of Northern Kazakhstan using ISSR markers. Seeds were collected from two populations in the Prigorodnoye forestry of the Kostanay region. ISSR analysis revealed a high level of polymorphism within populations (87 %) and a lower level between them (13 %). UPGMA clustering showed genetic differences both between and within populations, indicating heterogeneous origins and possible cross-pollination.
