Grapevine plant named ‘Sheegene 102’
‘Sheegene 102’ is a new grapevine plant with novel characteristics that include medium-large, red seedless grapes that mature in late August to September. The berries produced by ‘Sheegene 102’ are born on medium-strong woody stems and branches and are well adapted to commercial handling, providing a good fertility.
Latin name of the genus and species of the plant claimed: Vitis vinifera.
Cultivar denomination: ‘Sheegene 102’.BACKGROUND OF THE INVENTION
The present invention relates to a new distinct variety of grapevine named ‘Sheegene 102’. The variety originated from a hybridization performed in Mildura, Victoria, Australia during 2004 between ‘Crimson Seedless’ (unpatented), as the pollen parent, and ‘Red Globe’ (unpatented), as the seed parent. The resulting plant was planted in an evaluation block during 2006. The first evaluation of fruit produced by ‘Sheegene 102’ was performed during 2009. ‘Sheegene 102’ was first asexually propagated by field grafting dormant hardwood scions to rootstock in 2010 in Irymple, Victoria, Australia. Fruit from the resulting four grafted ‘Sheegene 102’ vines was first harvested in 2012. All characteristics and distinctions remain true to form and are established and transmitted through succeeding propagations.SUMMARY OF THE INVENTION
The following are the most outstanding and distinguishing characteristics of ‘Sheegene 102’. ‘Sheegene 102’ produces medium-sized bunches which exhibit a conical shouldered shape and ideal bunch density. The berries produced by ‘Sheegene 102’ are harvested in late August through September and exhibit an ellipsoidal shape, good size and evenness, and weigh on average 8.5 g/berry. These berries are characterized by their good eating quality, prominent and neutral flavour, and crispy texture.
‘Sheegene 102’ can be distinguished from its male parent, ‘Crimson Seedless’, based at least upon vigor, berry size, secondary cluster berry shape, and harvest period. ‘Sheegene 102’ displays a medium vigor; whereas; ‘Crimson Seedless’ displays high vigor. The berries produced by ‘Sheegene 102’ weigh on average 8.5 g/berry; whereas, those produced by ‘Crimson Seedless’ weigh on average 4 g/berry. Also, the berries within the secondary clusters of ‘Sheegene 102’ exhibit a more elongated shape than those within the secondary clusters of ‘Crimson Seedless’. ‘Sheegene 102’ is harvested from late August through September, which is earlier than the late September to early November harvest period of ‘Crimson Seedless’.
‘Sheegene 102’ and its female parent, ‘Red Globe’, both exhibit medium vigor and are harvested mid-season (late August to September). However, ‘Sheegene 102’ can be distinguished from its female parent, ‘Red Globe’, based at least upon berry size, shape, seed content, and firmness. The berries produced by ‘Sheegene 102’ are ovoid, seedless, weigh on average 8.5 g/berry, and are firm and crisp; whereas, those produced by ‘Red Globe’ are round, contain seeds, weigh on average 10 g/berry, and exhibit medium to low firmness.
‘Sheegene 102’ is illustrated by the accompanying photograph, which shows the form, foliage, and fruit of a 4-year-old vine grown in the field at Murcia, Spain. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.
The following detailed description sets forth the distinctive characteristics of ‘Sheegene 102’. The detailed description was obtained between March and November using 4-year-old plants grown in the field at Murcia, Spain. The color references are to the Munsell Plant Tissue Color Book, 2012 Edition by Munsell Color.
