Abstract
‘Sheegene 28’ is a new and distinct grapevine plant with novel characteristics that include small to medium-sized green (2.5 GY 8/8) seedless grape with a very good flavor for use as a table grape and in raisin production. The ‘Sheegene 28’ harvesting period for fresh fruit is the third week of June while the harvesting period for raisins is mid- to late-July, in the San Joaquin Valley of California.
Description
Latin name of the genus and species of the plant claimed: Vitis vinifera.
Variety denomination: ‘Sheegene 28’.
The present invention relates to a new and distinct variety of seedless grapevine named ‘Sheegene 28’. ‘Sheegene 28’ produces small to medium-sized, green, seedless grapes on bunches for use as a table grape or in raisin production. The new variety was first hybridized by Timothy P. Sheehan of Porterville, Calif., 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 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, Calif. The berry size is small to medium but with very good flavor and matures at least four weeks before ‘Thompson Seedless’. All characteristics and distinctions remain true to form and are established and transmitted through succeeding propagations.
The following are the most outstanding and distinguishing characteristics of ‘Sheegene 28’. ‘Sheegene 28’ produces small to medium-sized green (2.5 GY 8/8) seedless grape with a very good flavor and matures for harvesting and shipping in the third week of June in the San Joaquin Valley of Central California. The new variety most closely resembles ‘Thompson Seedless’ (not patented) but differs in maturity. Specifically, ‘Sheegene 28’ matures at least four weeks before ‘Thompson Seedless’ with a sweet and very good flavor. ‘Sheegene 28’ produces berries of 2 grams for fresh grapes and about 0.5 gram for Raisin grapes. Clusters weight about 454 grams. The variety is ideally suited for producing raisins by allowing grapes to wilt and naturally dry on the vine, or by cutting canes in mid- to late-July to accelerate drying, or by a combination of natural drying and cutting canes. In the San Joaquin Valley, ‘Sheegene 28’ fruit reaches full maturity by mid- to late-July with 21° Brix or more. Production potential is high and estimated at 20 Tn/hectare for fresh grapes and 4 to 5 Tn/hectare for dry grapes. Raisin quality is excellent with good sensory qualities and similar appearance to ‘Thompson Seedless’ (not patented). The new variety is similar to USDA variety ‘Sunpreme’ (U.S. Plant Pat. No. 26,527), in that fruit naturally begins to wilt by late-July and then dries to a raisin by mid-October.
The new variety is distinguished from its male parent, ‘Flame’ (not patented) in that ‘Sheegene 28’ produces green-colored grapes while ‘Flame’ produces red colored grapes.
‘Sheegene 28’ 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.
‘Sheegene 28’ matures four to five weeks earlier than all other commercial raisin varieties including ‘Fiesta’ (not patented), ‘Selma Pete’ (not patented), ‘Thompson Seedless’, ‘Flame Seedless’ (not patented), and ‘Supreme’. On July 30, the sugar concentration for ‘Sheegene 28’ was 26° Brix compared to 17° Brix for ‘Thompson Seedless’, 19° Brix for ‘Flame Seedless’, 18° Brix for ‘Sunpreme’, and 19° Brix for ‘Selma Pete’—all vineyards sampled located in close proximity.
Veraison is early for the ‘Sheegene 28’ variety when compared to other raisin varieties. On June 19, the ‘Sheegene 28’ was at 100% berry softening compared to 0% for ‘Thompson Seedless’, 5% for ‘Flame Seedless’, 30% for ‘Sunpreme’, and 1% for ‘Selma Pete’.
Bloom is also earlier for the ‘Sheegene 28’ variety. On May 1, ‘Sheegene 28’ was at 80% bloom; whereas, bloom had not started in any of the other varieties. All comparisons described above were made in the San Joaquin Valley of California.
An unusual characteristic of ‘Sheegene 28’ is the absence of secondary clusters even though the variety has plenty of lateral shoots.
The following detailed description sets forth the distinctive characteristics of ‘Sheegene 28’. The detailed description was obtained between March and November using 4-year-old plants grown in the field in California, USA. The color references are to the Munsell Color Charts for Plant Tissue, 1977 Edition by Munsell Color.
