Grape plant named `Gratitude`
Abstract
Description and specifications of a new and distinct grapevine
cultivar named `Gratitude` which originated from a hand-pollinated
cross of A-1925 (non-patented, non-released breeding genotype;
female).times.A-1581 (non-patented, non-released breeding genotype;
male). This new grapevine cultivar can be distinguished by its
seedless, green, crisp berries with neutral flavor and resists
cracking from rainfall at maturity. The fruit grows in large tight
clusters, the vines have medium vigor, and the plants are
healthy.

Claims
We claim:
1. A new and distinct cultivar of grape plant named `Gratitude`
substantially as illustrated and described.
Description
Latin name: Vitis labrusca L..times.Vitis vinifera L.
Varietal denomination: `Gratitude`.
BACKGROUND
The new and distinct cultivar of grape named `Gratitude` is
described herein. The new cultivar originated from a
hand-pollinated cross of A-1925 (female parent) and A-1581 (male
parent) made in 1991. The seedlings fruited in the summer of 1992
in a vineyard near Clarksville, Ark. and one was selected for its
seedless, green, crisp berries with neutral flavor. The fruit grows
in large tight 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
hand-pollinated cross of A-1925 (non-patented, non-released
genotype; female parent).times.A-1581 (non-patented, non-released
breeding genotype; male parent) made in 1991 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 1991-92.
Resulting seedlings were planted in the spring of 1992 in a
vineyard near Clarksville, Ark. The seedlings fruited in the summer
of 1994 and one seedling, designated Arkansas Selection 2505, was
selected for its seedless, green, crisp berries with neutral flavor
and resistance to fruit cracking in rainfall at maturity. The fruit
grows in large tight clusters, the vines have medium vigor and the
plants are healthy.
During late 1994 and early 1995, 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 has been very good, although
slight winter injury has occurred on the vines when winter lows of
5.degree. F. occurred but injury was not seen at winter
temperatures above this level.
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 late season, from August
19-28. The fruit is green in color at early maturity. It is evenly
colored within the cluster. The fruit shape is elongated oval.
Fruit skins are medium-thick and adhere to the flesh (has a
non-slipskin texture). The berries are medium (ca. 3.6 g). The
flavor is neutral in character. Solids concentration of the juice
at fruit maturity averages 19% with medium acidity. The fruit is of
the stenospermocarpic type of seedlessness and usually contains no
seed traces. Fruit clusters, borne usually one to two per shoot,
are large and tightly filled with an average weight of 516 g. The
fruit clusters are considered large in size, good for commercial
markets, and the variety is also intended for home garden
planting.
The new cultivar has been named the `Gratitude` cultivar.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs show typical specimens of the new
variety at eight years of age in color as nearly true as it is
reasonably possible to make in a color illustration of this
character.
FIG. 1 is a photograph showing typical specimens of the fruit.
FIG. 2 is a photograph showing the leaf adaxial view.
FIG. 3 is a photograph showing the leaf abaxial view.
DETAILED DESCRIPTION OF THE NEW CULTIVAR
`Gratitude` differs from its female parent A-1925 in that it is
seedless and has green berry color compared to blue color for
A-1925. `Gratitude` differs from it male parent A-1581 as this
parent is blue/black in fruit color, and has much smaller
clusters.
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.
