Latin name of the genus and species of the plant claimed: Vitis vinifera.
Cultivar denomination: ‘Sheegene 103’.BACKGROUND OF THE INVENTION
The present invention relates to a new distinct variety of grapevine named ‘Sheegene 103’. The variety originated from a hybridization performed in Mildura, Victoria, Australia during 2004 between ‘Stanley Seedless’ (unpatented), as the pollen parent, and ‘Crimson Seedless’ (unpatented), as the seed parent. Abortive seed traces were embryo cultured and the resulting plant was planted in an evaluation block during 2006. The first evaluation of fruit was performed during 2009. ‘Sheegene 103’ was first asexually propagated by field grafting dormant hardwood scions to rootstock in 2010 in Irymple, Victoria, Australia. Fruit from the resulting sixteen grafted ‘Sheegene 103’ vines was first harvested in 2014. 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 103’. ‘Sheegene 103’ produces large and naturally loose bunches. The berries produced by ‘Sheegene 103’ are red (5R 4/6) and exhibit a datiform shape, good evenness, and sweet, prominent flavor.
‘Sheegene 103’ can be distinguished from its male parent, ‘Stanley Seedless’, based at least upon berry color, shape, and length. ‘Sheegene 103’ produces red berries; whereas, ‘Stanley Seedless’ produces green yellow berries. The berries produced by ‘Sheegene 103’ exhibit a datiform shape; whereas, those produced by ‘Stanley Seedless’ exhibit a roundish shape. The berries produced by ‘Sheegene 103’ (37 mm on average) are longer than those produced by ‘Stanley Seedless’ (23 mm on average).
‘Sheegene 103’ can be distinguished from its female parent, ‘Crimson Seedless’, based at least upon berry size, shape, and diameter:length ratio, bunch size, bunch density, time of berry ripening, and harvest period. ‘Sheegene 103’ produces datiform berries with their average diameter being half their average length (18 mm diameter×37 mm length) and that weigh on average 8.5 g/berry. ‘Crimson Seedless’ produces oval berries with their average diameter more equal to their average length (16.6 mm diameter×22.2 mm length) and that weigh on average 4 g/berry. ‘Sheegene 103’ produces large, dense bunches of berries, whereas ‘Crimson Seedless’ produces bunches of berries exhibiting medium size and density. ‘Sheegene 103’ produces berries that exhibit early ripening, whereas ‘Crimson Seedless’ produces berries that exhibit medium to late ripening. ‘Sheegene 103’ is harvested in August, which is earlier than the late September to early November harvest period of ‘Crimson Seedless’.
‘Sheegene 103’ can be distinguished from ‘Sheegene 10’ (U.S. Plant Pat. No. 18,959) based at least upon berry shape and color. Berries produced by ‘Sheegene 103’ exhibit a datiform shape and red color. Berries produced by ‘Sheegene 10’ exhibit a broad ellipsoid shape and dark red violet color.
‘Sheegene 103’ can be distinguished from ‘Flame Seedless’ (unpatented) based at least upon berry shape, seed formation, bunch density, and time of berry ripening. Berries produced by ‘Sheegene 103’ exhibit a datiform shape and comprise rudimentary seeds. Berries produced by ‘Flame Seedless’ exhibit a globose shape and do not comprise seeds. ‘Sheegene 103’ produces dense bunches of berries, whereas ‘Flame Seedless’ produces bunches of berries exhibiting lax to medium density. ‘Sheegene 103’ produces berries that exhibit early ripening, whereas ‘Flame Seedless’ produces berries that exhibit very early ripening.
‘Sheegene 103’ can be distinguished from ‘Ralli Seedless’ (U.S. Plant Pat. No. 9,865) based at least upon berry shape and bunch density. Berries produced by ‘Sheegene 103’ exhibit a datiform shape, whereas berries produced by ‘Ralli Seedless’ exhibit a broad ellipsoid shape. ‘Sheegene 103’ produces dense bunches of berries, whereas ‘Ralli Seedless’ produces bunches of berries exhibiting lax to medium density.
‘Sheegene 103’ 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.DETAILED BOTANICAL DESCRIPTION
