Grape plant named ‘ND213’

Abstract

The grape plant cultivar ‘ND213’ is a red wine grape for white wine production which exhibits superior cold hardiness and disease resistance.

Description

Botanical designation:

Genus and species: Vitis spp. hybrid.

Variety denomination: The new plant has the varietal denomination ‘ND213’.

BACKGROUND

Most grape varieties used for production of high quality wines around the world are of the species Vitis vinifera. These V. vinifera varieties, when 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.

BRIEF SUMMARY

‘ND213’ is a variety of red grape (Vitis hybrid) suitable for white wine production and is well adapted to the Upper Midwest climate of the United States. ‘ND213’ exhibits a high level of cold hardiness, with trunks having survived −38° C. ‘ND213’ showed limited cold temperature dieback (winter injury) in comparison to the cold hardy gris wine grape ‘Frontenac Gris’ (U.S. Plant Pat. No. 16,478). The fruit of ‘ND213’ produces a good quality, well balanced wine with good body, attractive color, and notes of apple, citrus, stone fruit, grapefruit, and tropical fruit. ‘ND213’ exhibits good disease resistance, showing low susceptibility to powdery mildew (Uncinula necator), downy mildew (Plasmopara viticola), black rot (Guignardia bidwellii), and foliar phylloxera (Daktulosphaira vitifoliae).

‘ND213’ originated from a hand-pollinated cross of ‘C-16’ (female parent, not patented) and ‘Alpenglow’ (male parent, not patented) made in 2008. Asexual propagation of the new cultivar was accomplished by rooting dormant hardwood cuttings in 2015 in Fargo, ND. Asexual propagation of the cultivar by dormant hardwood cuttings has determined that the characteristics are stable and true to type in successive generations. ‘C-16’ arose from a cross between Vitis ‘Severnji’ and a Vitis riparia male pollen parent.

DETAILED BOTANICAL DESCRIPTION

‘ND213’ differs from male parent, ‘Alpenglow’, in that ‘ND213’ has a longer looser cluster with a more pronounced first lateral branch. ‘ND213’ stems were also more vigorous, and berries ripened to a deeper red. Data collected in 2018 in Fargo, ND reinforced observations where both cultivars were growing, but not in the same trial, with ‘ND213’ having 112% greater cluster weight and 2% greater berry weight than ‘Alpenglow’. Female parent, ‘C-16’, has not been characterized and plant material is unavailable for characterization. Thus, comparison to the female parent is not possible.

The following is a detailed botanical description of the new variety of grape plant, its flowers, fruit, foliage etc. as based on observations of various aged specimens grown in Absaraka, ND and Fargo, ND over the 2016-2021 growing seasons. All color references are taken from The Royal Horticultural Society (R.H.S.) Colour Chart, 5th Edition.
