DETAILED DESCRIPTION OF THE NEW CULTIVAR.
‘Joy’ differs from its female parent A-1919 in that ‘Joy’ is seedless and has smaller berries. ‘Joy’ differs from it male parent A-1908 as this parent is pink, and has thicker skins.
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.
• Vine:
o
Size.—Medium.
Growth.—Moderately vigorous.
Density of foliage.—Medium.
Productivity.—Moderate to highly productive.
Rootstock.—None; vines tested were own-rooted vines.
Cold hardiness.—Hardy to 5° C. (−15° C.); possibly more hardy as this was the coldest temperature experienced at the test site Shoots (current-season canes).—Color of shoots Yellow-Green Group (144A) consistent on all sides. Anthocyanin is not usually present, but if it is it is on the shoot sides exposed to direct sunlight. Shoot attitude is procumbent.
Canes (mature measured in winter).—Color of mature cane: base mostly Greyed-Orange Group (177 A and B); midpoint. Greyed Orange Group (177B); terminal Greyed-Orange Group (177B); anthocyanin not observed on mature canes at base, midpoint, or terminal. Length average 2.9 m with range of 1.8 to 4.8 m. Diameter of mature cane: base 0.92 cm, midpoint 0.60 cm, terminal 0.24 cm. Internode length: base 4.5 cm, midpoint 7.9 cm, terminal 2.6 cm. Lenticels present on mature canes at medium density and small (less than 0.5 mm in diameter). Canes mature to tips in the fall.

o
Leaves.—Leaves simple and alternate; shape palmate; number of lobes 1; petiole sinus shape open; venation palmate-pinnate; margin serrated with shape of teeth convex and teeth medium in size.

Color of mature leaves: base abaxial — Yellow-Green Group (147B); base adaxial — Green Group (137B); midpoint abaxial — Yellow-Green Group (147B); midpoint adaxial — Green Group (137B); terminal abaxial — Yellow-Green Group (147B and occasionally 146A); terminal adaxial — Green Group (137B and occasionally 146B). No anthocyanin on upper or lower surfaces of leaves or on leaf veins. Color of young leaves: base abaxial — Yellow-Green Group (146D); base adaxial — Yellow-Green Group (146B); midpoint abaxial — Yellow-Green Group (146D); midpoint adaxial — Yellow-Green Group (146C); terminal abaxial — Yellow-Green Group (150D); terminal adaxial — Yellow-Green Group (151C).
Petioles.—Color on young leaves — Yellow-Green Group (144A). Color of mature petioles — Yellow-Green Group (147B and occasionally 146C). Petiole anthocyanin present on mature leaves on areas most exposed to sunlight. Sinus of mature leaf is 3.5 cm deep and 15.6 cm at widest point. Mature leaves have sparse pubescence. Young leaves have light sparse pubescence on midrib, main veins and secondary veins.
Tendrils.—Found on the 6th node, opposite. Length 22.3 cm. Texture smooth and usually forked and curled on distal end. Color of mature tendril Greyed-Orange Group 177B. No anthocyanins present.

Жаль вот так посадят по рекомендациям без укрытия, а потом народ растраиватся будет когда вымерзнет и сорт ругать будут. Здесь на месте рекомендован до 6 зоны, это минимальные от -17, -23. Какие придуманные -28
