Bud-burst period: everage.
Ripening period: everage.
Yield: good and constant.
Ampelographic characters:
very homogeneous variety, the main differences concerning vigour and productivity. The bud, with an expanded apex, is velvety and whitish-green-colored with yellow shades. The leaves are medium-sized, almost whole, sometimes three-lobed are of a pale, shiny green color, with evident teeth. The V- or U-shaped petiolar sinus has edges that almost never overlap. The underside is arachnoid. The medium-small, cylindrical, compact cluster has only one wing. The medium-sized berry is spheroid in shape and more-or-less yellow in colour. The thick skin has an evident umbilicus and the flesh is juicy and sweet, with a simple flavour.
Cultural aptitude:
fairly vigorous vine, with a drooping but balanced growth habit. It adapts to different types of soil, provided they are not poor in magnesium or very humid, and possibly hilly. It accepts different climates, but it prefers dry ones.
Training system and pruning:
it adapts to different training and pruning systems, provided they are not too expanded and rich. For this reason, mechanising the various operations is easy with suitable training systems.
Susceptibility to diseases and adverse conditions:
normal. Very susceptible to magnesium deficiency. Good resistance to winter cold and spring frosts.
Enological potential:
it produces a straw-yellow, slightly scented wine, with a dry flavour, not very full-bodied, fairly alcoholic, pleasantly bitter and fruity, with a fragrant freshness when young. It is also suitable for production of sparkling and semi-sparkling wines.
Clones in propagation:
VCR364, VCR365, ISV1, FEDIT10, RI12V18, RI12V23.
Clones undergoing homologation procedure:
VCR367, VCR477, VCR298, VCR300, VCR303.
