Description and specifications of a new and distinct grapevine cultivar which originated from a hand-pollinated cross of Moored (non-patented)×NY 45791 (non-patented, non-released breeding genotype). This new grapevine cultivar can be distinguished by its seedless, pink berries of distinct V. labrusca-like flavor, small compact clusters, distinctly lobed leaves, medium vigor, and healthy plant.

Latin name: Vitis labrusca L.×Vitis vinifera L.
Varietal denomination: ‘A-1710’.
The new and distinct cultivar of grape named ‘A-1710’ is described herein. The new cultivar originated from a hand-pollinated cross of Moored and NY 45791 made in 1976. The seedlings fruited in the summer of 1979 in a vineyard near Clarksville, Ark. and one was selected for its seedless, pink berries with good flavor. The fruit grows in compact clusters, the vines have medium vigor and the plants are healthy.
The new and distinct cultivar of grapevine originated from a and-pollinated cross of Moored (non-patented; female)×NY 45791 (non-patented, non-released breeding genotype; male) made in 1976 near Clarksville, Ark. The instant cultivar is a hybrid of Vitis labrusca L. and Vitis vinifera L. The seeds resulting from this controlled hybridization were germinated in a greenhouse during the winter of 1976-77. Resulting seedlings were planted in the spring of 1977 in a vineyard near Clarksville, Ark. The seedlings fruited in the summer of 1979 and one, designated Arkansas Selection 1710, was selected for its seedless, pink berries of distinct V. labrusca-like flavor, small compact clusters, distinctly lobed leaves, medium vigor, and healthy plant.
During late 1979 and early 1980, the original plant selection was propagated asexually at the above-noted location, by rooting hardwood cuttings and a test planting of three vines was established. In all propagations hardwood cuttings were used and the instant cultivar rooted readily from hardwood cuttings. All propagules (resulting plants) of the instant cultivar have been observed to be true to type in that during all asexual multiplication, the vegetative and fruit characteristics of the original plant have been maintained. All vines planted from hardwood cutting propagation fruited in the second or third season of growth in the vineyard after planting.
Vines of the new cultivar have medium vigor, with a procumbent growth habit characteristic of V. labrusca. It has produced well as own-rooted plants in all testing and has not been evaluated on any rootstocks. Hardiness of the vines have been very good, with no winter injury to the vines to 5° F. in the most severe winters at the Arkansas test site.
The new cultivar is moderately resistant to powdery mildew (Erysiphe necator Schw. (syns. Uncinula necator (Schw.) Burr., E. tuckeri Berk., U. americana Howe, and U. spiralis Berk. & Curt; anamorph Oidium tuckeri Berk.), downy mildew (Plasmopora viticola Berl. & Tomi.), and anthrancnose (Elsinoe ampelina (d. By.) Sher), but susceptible to black rot (Guignardia bidwellii (Ell.) V. & R.). Fungal diseases can be controlled by the use of available fungicides.
The new cultivar ripens its fruit in the early season, average July 15. The fruit is pink in color at early maturity. It is evenly colored within the cluster. The fruit shape is round. Fruit skins are medium-thick and do not adhere to the flesh (has a slip-skin texture). The berries are medium-small (ca. 3.1 g). The flavor is very pronounced and distinctive, and of a V. labrusca character. Solids concentration of the juice at fruit maturity averages 22% with medium acidity. The fruit is of the stenospermocarpic type of seedlessness and can contain 1-2 small, soft vestigial seed traces that are not noticeable when eaten. Fruit clusters, borne usually two to three per shoot, are small, compact and tightly filled with an average weight of 150 g. The fruit clusters are considered limited in size for commercial markets and the variety is intended for home garden planting.
The new cultivar has been named the ‘A-1710’ cultivar.
The accompanying photographs show typical specimens of the new variety in color as nearly true as it is reasonably possible to make in a color illustration of this character.
‘A-1710’ differs from its female parent Moored in that it has smaller clusters, more pink-like berry color compared to red color for Moored, and is seedless. A-1710 has distinctly lobed leaves unlike either parent. A-1710 differs from it male parent NY 45791 as this parent is blue/black in fruit color, has much larger clusters, and the parent has more loosely filled clusters. A-1710 differs from a comparable Vitis labrusca cultivar Mars (U.S. Plant Pat. No. 5,680) in that A-1710 has much smaller clusters than Mars, pink fruit rather than black as Mars does, smaller berries than Mars, ripens approx. 3 weeks earlier than Mars, and has deeply lobed leaves while Mars leaves are only minimally lobed. Additionally, Mars is higher in vigor than A-1710. The following is a detailed description of the botanical and pomological characteristics of the subject grapevine. Color data are presented in Royal Horticultural Society Colour Chart designations, 1986 version, second edition.
Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations of averages set forth as accurately as practicable.
The descriptions reported herein are from specimens grown near Clarksville, Ark. Vines used for measurement were irrigated using trickle (drip) irrigation. The data collection was from vines that were 15 years old.
The most distinctive features of the cultivar are its seedless, pink berries of distinct V. labrusca-like flavor, small compact clusters, distinctly lobed leaves, medium vigor, and healthy plant.
