The global warming of the climate, a phenomenon that has significantly characterized the last decades, has considerably influenced the evolution of the thermal and water regime annually and during the growing season in the viticultural ecosystem of the Odobeşti vineyard, the atmospheric and pedological drought characterizing the last four years of viticulture. In this context, the use of drought-resistant rootstocks for grafting is one of the solutions to counteract this extreme phenomenon that is increasingly present in the wine-growing areas of southern Moldova. In the present paper, preliminary results are presented regarding the grafting affinity of three new vine varieties created at RDSVO Odobești (′Putna′, ′Măgura′ and ′Vrancea′), on three rootstocks with drought tolerance obtained by Romanian viticultural research (′Drăgășani 70 M.′, ′Crăciunel 71 Bl.′, ′Ruggeri 140 Vl.′). For comparison, the rootstock ′Berlandieri x Riparia Sel.Oppenheim 4 –4 Bl.′ was used, with the widest use for grafting in the Odobești wine-growing area. The preliminary results obtained show a good and very good grafting affinity on ′Ruggeri 140 Vl.′ rootstock. for all three varieties studied.
