Announcement of Three New Grape Varieties
Red Wine Grapes:
 |
Red wine grape released 10 July 2006:
'Corot noir'™ (formerly NY70.0809.10 - SV 18-307 x Steuben) produces a highly ranked
vinous, vinifera type wine. The vine is vigorous and very productive at
Geneva. Some cluster thinning is usually required to avoid overcropping.
Vines are healthy with good powdery mildew and Botrytis rot resistance
and often maintain green leaves up until frost. Fruit maturity is late,
with harvest Oct. 15-20 in Geneva.
Predicted temperature of 50% primary bud kill in mid winter = -15.1 F

Red wine grape released 10 July 2006:
'Noiret'™ (formerly NY73.0136.17 - [(NY33277 x Chancellor) x Steuben]) produces an
excellent full-bodied wine with a distinct pepper character and moderate
tannin content. Vines have generally been vigorous and productive in
the Finger Lakes of New York, though older vines occasionally show a
slow decline in vigor that may be indicative of a need for grafting.
The leaves show moderate resistance to powdery mildew, but both fruit
and leaves require a regular spray program to control downy mildew.
Fruit maturity is mid-season, approx. Oct. 1 in Geneva.
Predicted temperature of 50% primary bud kill in mid winter = -14.3

Red Wine Grape released, February, 2003:
GR 7 - ("Geneva Red 7") - (Buffalo x Baco noir) highly vigorous, highly productive and winter hardy, with moderate resistance to diseases. 'GR 7' makes dark red wines with a classical hybrid aroma. It has better tannin structure than Baco noir and De Chaunac. It still has a short finish. It is best made as a light (not heavily extracted) wine. Use hot pressing, short skin contact time or some carbonic maceration. It has a place in traditional red hybrid blended wines, and is already in limited commercial production.
Predicted temperature of 50% primary bud kill in mid winter = -17.1 F * |
White Wine Grapes:
 |
White wine grape released 10 July 2006:
'Valvin Muscat'™ (formerly NY62.0122.01 - Muscat du Moulin x Muscat Ottonel) produces an
excellent, high quality muscat wine that may be made into a dessert wine
or used in blending. Own-rooted vines are small (1.4 lb./vine in Geneva),
and therefore grafting is recommended. Though grafting improves vine size,
planting at somewhat closer than normal spacing (approx. six feet between
vines within rows) may also improve vineyard productivity. The fruit is
highly flavored, very juicy, and ripens mid-season.
Predicted temperature of 50% primary bud kill in mid winter = -14.6 F

NY76.0844.24 - (Traminette x Ravat 34) makes a top ranked floral,
muscat wine. Own rooted vines have been highly productive, highly vigorous
(24 lbs. of fruit/vine; 4.3 lbs. pruning weight average for '96-'03)
and very winter hardy. Clusters are large and loose. Leaf phylloxera
have been an occasional problem. Maturity is mid-season, ripening in
mid-late September in Geneva.
Predicted temperature of 50% primary bud kill in mid winter = -16.8

1996 Variety Releases :
 |
'Marquis' - Named and released for public use in 1996. (formerly
NY64.0029.01) - (Athens x Emerald Seedless) Fruit is yellow-green with
large, round berries (3.5 - 5.0g/berry), melting texture, and very flavorful.
Clusters are very large and attractive. Giberrellic acid treatment is
not recommended, but well-timed cluster thinning and girdling can increase
berry size and improve cluster appearance. Vines are moderately hardy,
medium in vigor and productive.
|
 |
'Traminette'- Named and released for public use in 1996. (formerly
NY65.0533.13) - (JS 23-416 x Gewürztraminer ) This Gewürztraminer
hybrid continues to produce wines of excellent quality, with good sugar/acid/pH
balance. The vine is much more winter hardy than its Gewürztraminer
parent, productive, and moderately resistant to powdery mildew. Maturity
is late mid-season, Oct. 5-10 in Geneva.
Predicted temperature of 50% primary bud kill in mid winter = -15.6 F * |
* - Please note that the actual temperature at which 50% primary bud kill
occurs will depend on vineyard care and local climate, including such factors
as the temperatures preceding the cold event, and the time of year when the
cold event occurs.
