The article presents the results of three years of researches conducted at the Department of Viticulture of Kuban State Agrarian University, to study the processes of shoots and rooting of the three-bud cuttings of grapes of Pervenets Magaracha, Podarok Magaracha and Cytrony Magaracha of the selection of Magarach Institute of Grape and Wine. The area of these varieties, which are inter-specific hybrids, in the Krasnodar region is more than 2 thousands hectares. The cuttings were rooted in sawdust in a greenhouse on a heated rack. It was found, that the regenerative capacity of cuttings was strongly dependent on the method of their storage prior to installation on the germination. The best results were obtained in the case when cuttings had been stored in the refrigerator before starting the experiment. The lowest impact of the way to store cuttings was on the percentage of cuttings with blossoming eyes, and the largest - the length of the shoots, the output of the cuttings with at least 3 of the roots, and the average number of roots developed on one cutting. Rooting of cuttings and their growth with three and more roots were different over the years for the varieties of Pervenets Magaracha and Cytrony Magaracha, in favor of one sort or another, but the average 3-year difference between varieties was not significant. On average, in two or three years, the maximum number of roots appeared in the variety of Cytrony Magaracha, which was a bit ahead of Pervene
ts Magaracha. The difference in the number of cuttings formed at the roots was authentic. Correlation analysis showed that the closest relationship to the performance of the rooting ability of cuttings was found in the length of the shoots. The level and the nature of the identified correlations suggests that the rooting ability of the cuttings of the varieties of Pervenets Magaracha was determined primarily by hormonal activity, Podarok Magaracha by its supply of plastic substances, and Cytrony Magaracha had equally both factors
