The article presents the results of a study on the study of the peculiarities of rhizogenesis of local grape varieties adapted to the conditions of Azerbaijan. The rooting of grapes in in vitro culture is determined by the mineral and hormonal composition of the nutrient medium, the morphological development of regenerated plant varieties. The culture of grapes, on average, takes root well both in natural conditions and on artificial nutrient media. However, obtaining a high quality root system (branched, without callus tissue at the base of the root) requires the determination of a suitable nutrient medium and cultivation conditions. The objects of the study were microcuttings of local grape varieties of Madrasa and Bayan Shirey, as well as Murashige and Skoog (MS) medium, modified with various combinations and concentrations of auxins and cytokinins (IBA, BAP, 2ip) in 9 variants. The research results showed that the main factors affecting the intensity and quality of rooting are the concentration and type of auxin in the nutrient medium. So, the optimal medium for in vitro rooting of both grape varieties was MS medium with an IBA content of 1.0 mg/l, except for the number of roots, the maximum number of which was obtained on MS medium with a 2.0 mg/l IBA content.
