This new grape plant named `14-44-248` is new and different because of its very large berry size, elongate berry and very firm, crisp texture. Fruit of the new variety ripens in mid-season producing a very sweet berry which is suitable for the domestic and foreign grape markets.

Genus and species: Vitis vinifera.
The new grape plant named `14-44-248` is of Vitis vinifera parentage. It resulted from an effort to provide an alternative to `Redglobe` (U.S. Plant Pat. No. 4,787) in the mid-season, seeded table grape market. Ripening of `14-44-248` is in the same period as `Thompson Seedless` (unpatented), achieving a sugar level of about 18 degrees brix in the second week of August. Fruit of the new variety hangs well on the vine and sugar levels continue to increase until the third week of September in the Delano, Calif. area. Pedicels of `14-44-248` are very slender and are prone to drying if held in cold storage for long periods of time.
The female parent (unnamed) resulted from a series of crosses involving `Hunisa`, `Flame Seedless`, `Emperor`, and `Thompson Seedless` (all unpatented). The male parent of the cross is `Fantasy Seedless` (unpatented). The hybridization resulting in `14-44-248` was made near McFarland, Calif. in 1993. Resulting seeds were stratified and sown in a greenhouse in January of 1994. Seedlings were transplanted to a field in the Delano, Calif. area in March of that same year. The original seedling vine of `14-44-248` was selected from a population of 127 seedlings of like parentage in 1996. it was then propagated by cuttings and grafting to `Freedom` (unpatented) rootstock near McFarland, Calif. Those resulting plants were stable and typical of the original vine. Subsequent propagations of the variety have also proven stable with true to type plants.
The new grape plant named `14-44-248` somewhat resembles the cultivar `Emperor`, from which it descends, but differs by having a much larger berry with crisper texture than fruit of `Emperor`. It differs from its female parent (unnamed) by having berries with dark red berries rather than white berries. It shares some characteristics with its male parent `Fantasy Seedless`, but differs by having a greater fruitfulness than `Fantasy Seedless`, allowing spur pruning of the vines. Berries of `14-44-248` have sclerified seeds, unlike `Fantasy Seedless`. Vigor of the new variety is reduced compared to that of `Fantasy Seedless`.
The accompanying drawings illustrate the following:
The following description of grapevine `14-44-248` contains references to color names taken from the Munsell Color Chart for Plant Tissues, published by Munsell Color, New Windsor, N.Y. Descriptors used herein conform to those set forth by the International Board for Plant Genetic Resources Institute Grape Descriptors (Vitis spp.) of 1983 and/or 1997 which were developed in collaboration with the Office International de la Vigne et du Vin (OIV) and the International Union for the Protection of New Varieties of Plants (UPOV) and published in Descriptors for Grapevine (Vitis spp.) (Anonymous, International Plant Genetic Resources Institute, 1997, ISBN 92-9043-352-3).
