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)×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.

Description

Latin name: Vitis labrusca L.×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)×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° 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

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.
