MANZONI BIANCO

VINES

Origin

The Manzoni 6.0.13 crossing, or rather the white Manzoni, is a vine obtained in the 1930s as part of a vine genetic improvement program conducted by Prof. Luigi Manzoni at the Conegliano Technical Agricultural Institute and in close collaboration with Prof. G. Dalmasso, director of the then Experimental Station for Viticulture, now CRA-VIT. It was obtained from the cross between the Rhine Riesling and Pinot bianco varieties. The genetic improvement program used the traditional crossing technique: the Rhine Riesling emasculated was used as a female parent, while Pinot Blanc was used as a male parent, as pollen donor.

Ampelographic Characteristics

  • posture: erect;
  • sprouts apex: semi-open with medium striated anthocyanin distribution;
  • leaf: medium-small. Pentagonal flap; five-lobed, dark green upper page, pentagonal-orbicular, V-shaped petiolar sinus, glabrous.
  • bunch: small, often with a wing, medium compact;
  • berry: the berry is small, spherical, with a rather thick skin.

Phenological and production characteristics

It has medium fertility with the first bunches already bearing the basal buds. The most used form of cultivation until a few years ago was the Sylvoz, but currently in the new plantings the choice of the Guyot is generally adopted due to the low vigor. The production is contained and due to the small size of the bunch (min 80 g, max 150 g). Since its establishment it has been positively evaluated for its excellent resistance to cryptogams (downy mildew and powdery mildew), but also against botrytis and esca disease.
