Abstract
The invention is a new and distinct variety of grapevine designated ‘La Crescent’, which has a combination of outstanding wine quality and cold hardiness.
Description
Botanical classification: Vitis vinifera.
Variety denomination: ‘La Crescent’.
Grape is one of the most widely planted and economically important fruit crops in the world. Currently, worldwide planting of grapevines exceeds 8.7 million hectares producing 60 million tons annually, with approximately 70% of the grapes being fermented into wine, 28% used for fresh fruit and the remainder used for dried raisins. In the U.S. alone, the grape crop is worth approximately $3 billion annually
Most grape varieties used for production of high quality wines are of the species Vitis vinifera. The discovery of winemaking, as well as the domestication of the wine grape, likely began in southern Caucasia (presently northwestern Turkey, northern Iraq, Azerbaijan and Georgia) at least 6000 years ago. Eventually, varieties of V. vinifera were cultivated throughout the Mediterranean region, then into Europe and Asia, and, ultimately, through European colonization to North America, South America and Australia. On all these continents, successful production of V. vinifera occurs predominantly in temperate climate zones similar to that of the indigenous range of V. vinifera in Eurasia, e.g., summers that are sunny, warm, and dry, and winters that are mild and rainy. V. vinifera varieties cultivated in northern regions of the United States with a continental climate are often subject to serious injury or death from low temperatures during winter. Although several wild Vitis species occur in colder regions of North America and eastern Asia, the wine made from these species generally has serious defects. Thus, there is a need for grape varieties that are winter hardy, yet produce fruit capable of yielding high quality wine.
‘La Crescent’ is a variety of grape (Vitis sp.) that has a unique combination of outstanding wine quality and very high cold hardiness not found in existing grape varieties. Fruit of ‘La Crescent’ can be fermented to produce white wine having desirable aromas of citrus, apricot, pineapple, and muscat (as found in Riesling or Vignoles varieties) and lacks ‘foxy’ aromas associated with V. labrusca and herbaceous aromas associated with V. riparia. As grown in east central Minnesota, the plants of ‘La Crescent’ plants are moderately vigorous and very winter hardy. The vines are somewhat resistant to phenoxy herbicide injury and moderately susceptible to foliar phylloxera (Daktulospahira vitifoliae) damage. Downy mildew, caused by Plasmopara viticola, has been observed at moderate levels on the foliage, but has not been seen on the fruit. Powdery mildew disease, caused by Uncinula necator, has been seen at low levels on the foliage, but not on the fruit. The disease black rot, caused by Guignardia bidwellii, has been observed sporadically and at low levels on the leaves, but not on the fruit. ‘La Crescent’ vines set a light to moderate crop load that varies from year to year. The fruit are borne on a loose, medium sized cluster. The berries are small to medium sized and amber with a waxy bloom at maturity. In some years, a small percentage of the berries have been observed dropping from the cluster before or during harvest. The berries have not been observed to split, even under wet conditions in the autumn. The fruit at harvest is usually relatively high in sugar and moderate to high in acidity.
The accompanying color photograph shows characteristics of ‘La Cresent’ grown under typical field conditions. The photograph depicts color features as true as is reasonably possible.
‘La Cresent’ arose from a controlled cross as part of the grape breeding program at the University of Minnesota Horticultural Research Center (HRC) in Carver County, Minn. ‘La Crescent’ was a seedling from the cross designated GE 8824 made in 1988 and having the parentage ‘St. Pepin’בE.S. 6-8-25’. The ‘St. Pepin’ variety is described in U.S. Pat. No. P.P. 5,771. The ‘E.S. 6-8-25’ variety is an unnamed selection resulting from a V. ripariaבMuscat Hamburg’ cross. ‘La Crescent’ was selected as an initial seedling vine at location Block 1 Row 19 Post 9.9 at the HRC in 1992. A total of 11 vines of ‘La Crescent’ were asexually propagated by hardwood cuttings and planted at the HRC as follows: 3 plants were planted in 1995 in Block 10 Row 8; 5 plants were planted in 1997 in Block 18 Row 8; 2 plants were planted in 1998 in Block 20 Row 3; and 1 plant was planted in 1999 in Block 1 Row 19. These plants were observed through 2002, including their fruit, and were indistinguishable in appearance from the original ‘La Crescent’ seedling. Therefore, the progeny of ‘La Crescent’ are stable and reproduced true to type in successive generations.
‘La Crescent’ has perfect flowers containing extended stamens with anthers having viable pollen, whereas the ‘St. Pepin’ parental variety has functionally pistillate flowers (female only) with reflexed stamens having anthers with inviable pollen. When ripe, the berries of ‘LA Crescent’ are yellow-amber and contain little or no anthocyanin pigment, whereas the ‘E.S. 6-8-25’ parental variety produces highly pigmented dark blue berries.
The following data pertains to vines grown at the University of Minnesota Horticultural Research Center in Carver County, Minn. near Excelsior. For comparison purposes, data were collected for certain morphological descriptors from plants and fruit of the variety Seyval, a grape variety commonly grown in Minnesota and the eastern U.S. for the production of white wine. Seyval is a parent of ‘St. Pepin,’ and thus a grandparent of ‘La Crescent’. Alphanumeric color designations refer to values based on The R.H.S. Colour Chart published by The Royal Horticultural Society, London, England. Many of the descriptors are based on those set forth by the International Board for Plant Genetic Resources in collaboration with the Office Internationale de la Vigne et du Vin (OIV) and the International Union for the Protection of New Varieties of Plants.
When dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations set forth as accurately as possible. Variations of the usual magnitude incident to climatic factors, fertilization, pruning, pest control and other cultural practices are to be expected.
