Black Monukka: a purplish-black grape that, except for colour, is similar in most respects to Thompson Seedless. Although it is hurt by temperatures that go below -23 °C, it recovers well and is well worth keeping due to it's very high fruit quality. Although a very old variety it is one of the best eating grapes. Berries are large with tender skin. Bunches are medium-large and loose. Flavour is crisp and sweet. Cane or spur pruning.

Canadice: early ripening, more winter hardy than most seedless grapes, although trunk injury has occurred on some sites. It produces medium (6" - 8") clusters with small red berries that have a spicy grape taste. Excellent for fresh use, good for juice, jelly, and wine.
Vigorous grower; sets lots of fruit reliably. With cordon training systems and careful management, vines can be extremely productive. Fruit rot is a problem in wet years because the clusters are excessively compact.
Bunch weight = 227 gm. Berry weight = 1.6 gm.

Concord Seedless: though similar in flavour and texture to Concord,  it is unrelated. The clusters and berries are much smaller than those of Concord. The fruit matures a week earlier, has high flavour, and makes excellent pies, jiuce and preserves. Productivity is erratic, and it is not recommended for commercial planting. In warm years, the variety produces fully developed seeds. It requires too much summer heat to ripen well in Western Washington but is ok in hotter parts of USA.

Einset Seedless: early-ripening, winter-hardy, red seedless grape with a unique strawberry-like flavour. The medium-sized clusters produce bright red, oval berries with tender skin. Cultural problems include susceptibility to fungal diseases. Along with Vanessa, it has probably the most commercial promise of the red seedless varieties that can be grown successfully in New York.
Bunch weight = 145 gm. Berry weight = 2.3 gm.

Emerald Seedless: large attractive uniform bunches, conical, loose to well filled. Berries medium to large, greenish yellow with  tender skin. Extremely susceptible to powdery mildew and somewhat susceptible to sunburn, so efforts must be made to prevent this. Harvested between September 10 and October 15.

Fantasy Seedless: mid-season blue-black seedless. Large, firm, crunchy, flavourful berries. It has a moderately low, non-reliable productivity in some areas.

Flame Seedless: early ripening, red, crisp, sweet fruit. Good for fresh use, or it also a good raisin. Firm skin resists cracking. High vigour and productivity. Vinifera parent. America's most popular red seedless grape, found everywhere in supermarkets.

Glenora: ripens early to mid-season. Medium to large clusters of small to medium, seedless, blue-black grapes with tender skin. Sweet, spicy, fine textured, highly flavoured flesh. Keeps well on the vine. Red-orange autumn foliage.

People who taste the fruit like it, saying it tastes "like blueberries". It is sweet, crisp, seedless and flavourful. A favourite home garden grape.

Himrod: very early ripening. It produces large bunches of medium size tender-skinned greenish-white berries with sweet, delicious, honey-like flavour and melting, juicy texture.
The clusters are loosely filled, but cane girdling, gibberellic acid treatments, or thinning may be used to increase cluster compactness and improve berry size. Despite some cultural defects, Himrod is currently the most commercially important of the seedless grapes grown in New York. Cane pruning is advised.
Bunch weight = 163 gm. Berry weight = 2.1 gm.

Interlaken: very early ripening. Has a strong, pleasant, tangy flavour, excellent for fresh eating or raisins. Vigorous, disease resistant, bearing medium sized compact bunches, with small-medium greenish-white berries with a slip skin. Birds often cause crop loss.
Bunch weight = 122 gm. Berry weight = 1.5 gm. Though an older variety, it is very hardy, productive and flavourful. As an eating grape it is still superior to many of the new tough-skinned seedless releases.

Jupiter: ripens early to mid-season. Plant patent 13,309 from the University of Arkansas, produces naturally large, oval, firm, tender, slip-skin, red-blue berries on medium sized bunches. The flavour is excellent, with a mild muscat character. Relatively new variety, it is said to be very productive, and more winter hardy than Marquis and Himrod, but not as hardy as Reliance and Mars.
Berry weight = 4 to 5 gm in Arkansas.

Lakemont: ripens early to mid-season. Somewhere between Himrod and Interlaken, Lakemont has large tight clusters of small to medium sized greenish-yellow berries with tender skin, having milder but excellent flavour.
Cluster thinning prevents overcropping. Bunch rot is often a problem. Keeps well in cold storage.
Bunch weight = 218 gm. Berry weight = 1.7 gm.

Marquis: ripens mid-season. Clusters are very large, fairly compact and attractive, with large, round, yellow-green berries. Texture is melting, and the taste is very flavourful. Ripe fruit holds well on the vine, with the flavors going from a mild fruity flavour when first ripe, to a stronger Labrusca flavour two weeks later. Giberrellic acid treatment is not recommended, but well-timed cluster thinning and cane girdling can increase berry size and improve cluster compactness. Vines are moderately hardy, medium in vigour and productive.
Berry weight = 3.0 to 5.0 gm.

Mars: early ripening. Plant patent 5680, a release from the University of Arkansas, is a vigorous, blue-black seedless grape. The flavour is mildly labrusca, similar to Campbell's Early, and the berries have a 'slip skin' (a tough skin that separates readily from the pulpy flesh). Clusters are medium sized, cylindrical, and well filled. Hardiness has been good at Geneva, New York, and the vines are resistant to several major diseases. Vines may bear fruit precociously, and production should be controlled on young vines to prevent delays in establishment. A home garden grape with limited potential for commercial marketing.
Bunch weight = 181 gm. Berry weight = 2.6 gm in Arkansas.

Neptune: ripens mid-season. Plant patent 12,302, a 1998 release from the University of Arkansas. A medium-large yellow-green berry with a slip skin (the skin slips easily away from the grape). The clusters are large and very showy, but productivity is moderate. Flavour is mild and fruity (muscat), while fruit texture is firm with a relatively thick skin that resists cracking, similar to many eastern seedless grapes. Of moderate vigour, it is reported to be more winter hardy than Venus.
Berry weight = 3 gm in Arkansas.

Reliance: ripens early to mid-season, very reliable. Plant patent 5174, also from the University of Arkansas (1982), produces large clusters of round, red, medium-sized berries with a semi-slip skin. The skins are tender and the flesh is melting in texture, with a sweet labrusca flavour. Colouring may be poor in some years, and fruit often crack in wet seasons. Cold hardiness is among the highest of the seedless varieties.
Bunch weight = 280 gm. Berry weight = 2 to 3 gm in Arkansas.

Remaily Seedless: ripens mid-season. Produces large clusters of oval seedless berries with firm 'meaty' texture. Highly productive so often requires cluster thinning.
The flavour is neutral and mildly fruity. The clusters are very attractive in appearance but are subject to bronzing where exposed to sunlight, and the vines are only moderately hardy. This variety is recommended for backyard gardeners interested in a neutral-flavoured, European-type grape that is more winter hardy than commercially grown California seedless grapes.
Bunch weight = 308 gm. Berry weight = 2.7 gm.

Romulus Seedless: bunches are medium (to large) size, long, compact. Berries are small (to medium), round, yellowish-white, with tender skin, soft flesh and pleasant flavour. It ripens later then most so it extends the season. The fruit is good quality and stores well. Hardy to -23 °C.

Saturn: ripens mid-season. Plant patent 6703, another University of Arkansas release (1987), produces large, crisp berries on medium-large conical clusters. The berries are bright red with adherent skins and a mild flavour. Vines are precocious and moderately hardy at best and must be cluster thinned. In some years the seed remnants are very noticeable, especially in hot weather. Saturn has good storage potential and may be processed into an acceptable blending wine. Hardy to -23 °C.
Bunch weight = 308 gm. Berry weight = 3.0 gm in Arkansas.

Suffolk Red: ripens early to mid-season. Produces medium to large clusters of pink to bright red, round firm berries with a mild spicy sweet flavour. The clusters are loose but may be made more compact with the use of gibberellic acid or cane girdling. Winter damage is often a problem except on Long Island, where the variety is successfully cultured. Excessive vigour may occur following poor crops and winter bud damage.
Bunch weight = 145 gm. Berry weight = 2.7 gm.

Suffolk Red is very hardy, productive, and appreciated by all who test the fruit. The fruit is sweet and flavourful, with a melting, soft texture, not crisp. It is a pleasant eating experience, but when fully ripe the cluster falls apart fairly easily, and the fruit crushes and cracks when piled up, so transport to markets could be difficult. It is a good choice for a garden. Reliance may be superior.

Vanessa: early ripening. Developed by HRIO, Canada, and is a red dessert grape of excellent quality. The vine is moderately vigorous and among the hardiest of seedless grapes. Grafting may be desirable on many sites to increase vine size (vines grafted on 5C at trials in Fredonia, New York, however, have shown poor fruit set with very small berries). The seed remnant is usually large and soft; when noticeable it is sometimes a cause for limited marketability. Deep-red berries are oval, medium in size on medium-loose well-filled clusters. The flavour is mild and fruity. Berry texture is firm and resists rain. Storage potential is good. The fruit quality is among the best of the red seedless types.

Venus: ripens early to mid-season. Also from the University of Arkansas, is a vigorous and productive blue-black seedless grape. Medium-large clusters of large berries with mild labrusca flavors. In New York, the seed remnants are hard and noticeable, and fruit rot has been a problem at harvest. Fruit quality is only fair. Red-orange autumn foliage.
Bunch weight = 272 gm. Berry weight = 2.9 gm.
