| Neptune |
| (Plant patent 12,302), a 1998 release from the University of Arkansas, is a yellow-green seedless grape cultivar of moderate vigor. The clusters are large and very showy, but productivity is moderate. Flavor is mild and fruity, while fruit texture is firm with a relatively thick skin, similar to many eastern seedless grapes. There is relatively little experience growing Neptune in New York. It is reported to be more winter hardy than Venus. |
| New York Muscat |
| reddish-blue grape with a rich muscat-labrusca flavor. The vines are moderately vigorous and produce medium-sized, loosely filled clusters. |
| Niabell |
| blue-skinned, seeded, very large round fruit that is sweet to semi-sweet. Slip-skin Concord type. Ripens mid-season. |
| Niagara |
| These large, amber-colored grapes have a grayish bloom. Niagaras may be either round or egg-shaped. They are somewhat coarse-fleshed, and are less sweet than most other American varieties. They are often sold as white Concord grapes and are used to make white grape juice. |
| Niagra |
| green-skinned, seeded, medium to large oval fruit; the flesh is juicy, foxy and sweet. Ripens mid-season. |
| Norton (Cynthiana) |
