Rezumat

The research followed the behaviour of white grape vine varieties in the ampelographic collection over a ten-year period (2012-2021). The fertility of the shoots, recorded different values depending on the variety and climatic conditions. The relative fertility coefficient recorded both subunit and superunit values depending on the year, with one exception, the variety Fetească regală Cl. 21 Bl., where the values were only superunitary (1.13-1.67), while the maximum value of the absolute fertility coefficient was recorded for the variety Blasius, ranging from 1.23 to 2.10. In terms of average grape production, for the period 2013-2021, the varieties Brumariu stood out with a production value of 15828 kg/ha and Selena with 13729 kg/ha. At the opposite end of the scale were Columna (8095 kg/ha) and Donaris (7764 kg/ha). Total sugar content values at harvest maturity varied from variety to variety and from year to year. In this respect, the Selena variety came first, with an average total sugar content of 210 g/l. Columna had the lowest average total sugar content (167 g/l).
