Research on the agrobiological and technological potential of some hybrid elite with biological resistance obtained at r.d.s.v.v. odobesti

The practice of sustainable viticulture by reducing the quantities of pesticides applied by phytosanitary treatments and capitalizing on the ecopedoclimatic conditions specific to each wine-growing area, involves obtaining and promoting vine varieties with complex biological resistance, with high potential for adaptation to changes caused by climate change and valuable agrobiological and technological potential. In response to this, at R.D.S.V.V. Odobesti were studied in order to evaluate the agrobiological and technological potential three hybrid elites with biological resistance: hybrid elite 10-1-6 (Traminer roz x Isabella), hybrid elite 2-5 (Galbena de Odobesti x Lydia) and hybrid elite 10-18 (Riesling italian x Siebel 6720). This paper presents the ampelographic description and the agrobiological and technological potential of the elites studied during the years 2020- 2021. The results obtained from this study showed that these hybrid elites have high productive and qualitative potential, show high biological resistance to the main diseases of the vine, and can be proposed for approval in order to improve the national assortment, in the context of sustainable viticulture
