Abstract

‘Sheegene 29’ is a new and distinct grapevine plant with novel characteristics that include good fertility, medium sized green (2.5 GY 6/2) seedless grape with a very good flavor for use in raisin production. The raisins have a unique candy-like apricot flavor and a bright golden color. The ‘Sheegene 29’ harvested period for fresh fruit is late August in the San Joaquin Valley of Central California.

Description

Latin name of the genus and species: Vitis vinifera.
Variety denomination: ‘SHEEGENE 29’.
BACKGROUND
The present invention relates to a new and distinct variety of seedless grapevine named “Sheegene 29”. ‘Sheegene 29’ produces medium-sized, green seedless grapes on bunches for use in raisin production. The new variety was first hybridized by Timothy P. Sheehan of Porterville, California as a cross of ‘Flame’ (not patented), as the pollen parent, and ‘Red Globe’ (U.S. Plant Pat. No. 4,787), as the seed parent, in 2000. The new variety was first asexually propagated in the dormant season of 2004, grafted on ‘Harmony’(not patented), virus free rootstock, in a Vitis vinifera variety block located near Fowler, California. ‘Sheegene 29’ produces a golden seedless raisin (treated with sulfur and then dried in a dehydrator) that has a unique candy-like apricot flavor and a bright golden color that matures at the same time as ‘Thompson Seedless’. All characteristics and distinctions remain true to form and are established and transmitted through succeeding propagations.
SUMMARY
The following are the most outstanding and distinguishing characteristics of ‘Sheegene 29’. ‘Sheegene 29’ produces medium-sized green (2.5 GY 6/2) seedless grape with a very good flavor and matures for harvesting and shipping in late August in the San Joaquin Valley in Central California. The new variety most closely resembles ‘Thompson Seedless’ (not patented) but differs in fresh berry size and attachment strength. Specifically, ‘Sheegene 29’ fresh berry weight is 2.5 grams which is larger than the 2.0 grams berry weight for Thompson. The berries of ‘Sheegene 29’ have medium attachment strength and shatter is not an issue at full maturity as occurs with ‘Thompson Seedless’.
The new variety is ideally suited for producing raisins by a dehydrator because its late maturity makes it not suitable for dried-on-vine raisin production. In the San Joaquin Valley, ‘Sheegene 29’ produces clusters of about 650 grams and the fruit reaches full maturity by late August with 20° Brix or more. Production potential is high and estimated at 60 Tn/hectare for fresh grape and 14-15 Tn/hectare for dry grapes, without impacting sugar maturity or production the following year. Raisin quality is excellent with good sensory qualities and similar appearance to ‘Thompson Seedless’ (not patented), ‘Fiesta’ (not patented) and ‘Selma Pete’ (not patented).
The new variety is distinguished from its male parent, ‘Flame’ (not patented) in that ‘Sheegene 29’ produces green-colored grapes while ‘Flame’ produces red colored grapes. ‘Sheegene 29’ matures two weeks later than ‘Flame’.
‘Sheegene 29’ is distinguished from its female parent, ‘Red Globe’ (U.S. Plant Pat. No. 4,787), in that the new variety produces green seedless grapes, as compared to its seed parent ‘Red Globe’ (U.S. Plant Pat. No. 4,787), that produces seeded grapes. The vigor of ‘Sheegene 29’ is greater than ‘Red Globe’.
‘Sheegene 29’ presents characteristics that distinguish it from other raisin cultivars, such as large leaves that are deeply lobed and overlapped, lateral shoots that are infrequent, and lateral clusters that are absent. Lateral clusters are also absent on Sheegene 28 (U.S. Plant Pat. No. 34,211). Vigor is medium-high which is similar to ‘Thompson Seedless’, ‘Selma Pete’, ‘Sheegene 27’, (U.S. Plant Pat. No. 29,129) ‘Sheegene 28’, and ‘Flame Seedless’. Vigor is greater than ‘Fiesta’. Sugar maturity is similar to ‘Thompson Seedless’, a week later than ‘Selma Pete’ and ‘Sheegene 27’, and three to four weeks later than ‘Sheegene 28’.
