In 2015, we at the University Center for Viticulture and Enology Meranovo, Faculty of Agriculture and Life Sciences, studied the length of the vegetation and sensory properties of 81 table grapes varieties. The length of the vegetation of individual varieties was determined by the system BBCH. Studied varieties are divided into a very early, early, medium late, late and very late depending on the time of ripening cultivar 'Red žlahtnina'. Sensory evaluation was performed by means of tasting the grapes of each variety of technological maturity (65 to 75 ° Oe). In the period between 11. 8. -22. 9. 2015 we conducted five tastings. The varieties were divided according to the color of grape skins and origin (vinifera varieties or interspecific hybrids). The length of the vegetation, a median of 155 days at the white, 135 days for the pink and 140 days at the blue varieties. Resistant varieties in quality not different from varieties of Vitis vinifera L., because the sensory assessment did not find statistically significant differences between them. The experiment showed that the production in Slovenia suitable for both white and blue and pink varieties of table grapes.

COBISS.SI-ID: 4118572In 2014, we at the University Center for Viticulture and Enology Meranovo monitor the phases of development of some resistant varieties of table grapes. We monitored the number of days elapsed in each variety of sprouting (BBCH 05) the technological maturity (BBCH 89). Technological maturity of the grapes was determined by analysis of the sugar content (65 to 75 ° Oe) and the sensory evaluation of maturity. Phase budding first (March 21) occurred at the variety 'Einset seedless', the latest (April 7)at varieties 'Sophie', 'Angel' and 'Schuyler'. Depending on the duration of the vegetation (from sprouting until technological maturity) are a group of early varieties (130-145 days) ranked the variety 'Xenia' 'Reflex', 'Prima', 'Black Magic', 'Kyoho', 'Clara' and ' Vierul 59 '. In the group of medium-late varieties (146-165 days) were classified varieties 'Prezentabil' 'Patrizia' 'Primus' 'Galant', 'Carmen', 'Sophie,' 'eins seedless', 'Angel' and 'Schuyler' . Among the late varieties (165 days and more), we ranked the variety 'Muscat Blue', 'Ontario', 'Teresa' and 'Guzun'. In sensory evaluation, we found that the skin of berries most distracting the variety 'Schuyler', but at least the variety 'Black Magic'. The seeds were the most distracting the variety 'Muscat Blue', but at least in the varieties 'eins seedless', 'Black Magic' and 'Evita'. Most evaluators to buy a variety of 'Prima', 'Evita' and 'Primus', almost no one would have bought varieties 'Guzun'.
