Grapevine plant named ‘Sheegene 27’
A new and distinct grapevine plant named ‘Sheegene 27’ is described herein. The claimed variety was developed as a table grape and for raisin production, having uniform medium-sized, green, globose, seedless fruit weighing approximately 3 g each and having a crisp texture and neutral flavor. Harvest is in late-July to mid-August.

Variety denomination: ‘Sheegene 27’.BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct variety of grapevine named ‘Sheegene 27’. ‘Sheegene 27’ produces medium-sized, green-yellow, seedless grapes on bunches for use as a table grape and in raisin production. The variety originated from a cross of ‘Very Early Flame’ (also known as ‘VEF’) as the pollen parent and ‘Red Globe’ (U.S. Plant Pat. No. 4,787) as the seed parent. ‘Sheegene 27’ was first asexually propagated in the San Joaquin Valley of California. All characteristics and distinctions remain true to form and are established and transmitted through succeeding propagations.SUMMARY OF THE INVENTION
The present invention relates to a new and distinct grapevine plant called ‘Sheegene 27’. ‘Sheegene 27’ produces medium-sized berries averaging 3 g per berry. The berries are harvested in late-July to mid-August. Comparison can be made to ‘Thompson Seedless’ (unpatented), which is also a green, seedless grape grown for both table grape and raisin production. ‘Sheegene 27’ matures 10 days earlier than Thompsons Seedless, and about the same time as Selma Pete, a grape cultivar grown for raisin cultivation. Berries of ‘Sheegene 27’ are globose, while both Thompson Seedless and Selma Pete are ellipsoid pointed. Thompson Seedless and Selma Pete berries weigh approximately 2 grams, while ‘Sheegene 27’ berries are larger, weighing around 3 grams.
‘Sheegene 27’ is illustrated by the accompanying photograph, taken of a 5-year-old vine, which shows the plant's vines, foliage, and fruit. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.
