The behavior of Putna table grape variety in the Odobeşti vineyard in the conditions of years 2020-2022

Abstract

The study falls within the general context of research on the agrobiological and technological value of vine varieties for table grapes existing in the culture, adapted to the changing climatic conditions permanent. The ʹʹPutna variety was obtained at RDSVO Odobești through intraspecific sexual hybridization between the ʹCeaușʹ x ʹMuscat de Alexandriaʹ varieties and approved in 2014. In the climatic conditions of the study period (2020-2022) the ʹPutnaʹ table grape variety showed good fertility (70.2% fertile shoots), medium growth vigor good tolerance to the main cryptogamic diseases. Medium-sized grapes (299.7 g) reached consumption maturity in the first decade of September, achieving an average production of 5.97 kg/bunch, of which 82.9% was commodity production. It showed a high potential for the accumulation of sugars in the grains (187.7 g/L), with an average total acidity value of 4.6 g/L H2SO4, very well balanced glucoacidimetrically (27.3), that place it in the group of valuable table grape varieties.
