Claims
We claim:
1. A new and distinct cultivar of grape plant named `A-1710`
substantially as illustrated and described.
Description
Latin name: Vitis labrusca L..times.Vitis vinifera L.
Varietal denomination: `A-1710`.
BACKGROUND
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.
SUMMARY OF THE INVENTION
The new and distinct cultivar of grapevine originated from a
and-pollinated cross of Moored (non-patented; female).times.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.degree. 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.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
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.

DETAILED DESCRIPTION OF THE NEW CULTIVAR
`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.
