ABSTRACT:
Genus and species:
Vitis vinifera.
BACKGROUND AND SUMMARY OF THE INVENTION
The new table grapevine ‘12-76-71’ is of
Vitis vinifera
parentage and resulted from an eighteen year breeding program which had as its goal the development of a grapevine bearing red, seedless, muscat-flavored grapes. The female, seeded parent was the patented grapevine ‘Redglobe’ (U.S. Plant Pat. No. 4,787). The male parent of the cross was an unnamed, unpatented grapevine designated as grapevine ‘7-7-2’. Grapevine ‘7-7-2’ bears red, seedless, muscat-flavored berries and descends from a wine grape ‘Red Muscatel’ and ‘Flame Seedless’ (both unpatented). The hybridization resulting in grapevine ‘12-76-71’ was made near McFarland, Calif. in 1991. Seeds from this cross were harvested, stratified and planted in a greenhouse. The resulting seedling population totaled 24 individual plants. All seedlings were subsequently transplanted to a field near McFarland, Calif. in March, 1992. Grapevine ‘12-76-71’ fruited in 1993 and was selected for further propagation. It was then propagated by cuttings in McFarland, Calif. and was grafted to ‘Freedom’ rootstock in 1995 in. This new variety has been found to retain its distinctive characteristics through successive propagation and this novelty is firmed fixed.
The new grapevine variety, grapevine ‘12-76-71’ is similar to its male parent variety ‘7-7-2’, but differs from it by having a much larger berry with firmer flesh. It differs from its female parent ‘Redglobe’ by having a seedless (stenospermic) berry of much smaller size than that of ‘Redglobe’. Fruit cluster size is much smaller than that of ‘Redglobe’ as well. Harvest time of ‘12-76-71’ is similar to that of its male parent ‘7-7-2’, about two weeks before ‘Redglobe’ in McFarland, Calif. It differs from other red, seedless varieties such as ‘Crimson Seedless’ (unpatented) and grapevine ‘3-14-71’ (U.S. Plant Pat. No. 8,297) by ripening about two weeks earlier in the McFarland, Calif. area and by having a strong, muscat flavor.
