Description

Latin name of the genus and species claimed: Prunus armeniaca.

Variety denomination: ‘SUAPRI15’.

BACKGROUND AND SUMMARY OF THE INVENTION

This application relates to the discovery and asexual propagation of a new and distinct variety of apricot tree, Prunus armeniaca ‘Suapri15’. The new variety was first originated by hybridization and identified in May 2011 by Terry A. Bacon as breeder number ‘AP13141’.

The seed parent is ‘Robada’ (U.S. Plant Pat. No. 9,890), and the pollen parent is unknown (from a bulk pollen of unpatented breeding program selections). The parent varieties were first crossed in February 2008, the date of first sowing being February 2009 and the date of first flowering being February 2011. The new apricot variety ‘Suapri15’ was first asexually propagated by Terry A. Bacon near Wasco, Kern County, Calif. in February 2012 by dormant grafting.

The new variety ‘Suapri15’ is characterized by having fruit that is medium sized, with smooth skin and dark orange flesh that ripens midseason. The fruit of the new variety ‘Suapri15’ also has firm flesh, a mildly sweet flavor with abundant aroma and a stone that has very weak adherence to the flesh.

The new variety ‘Suapri15’ differs from its seed parent ‘Robada’ (U.S. Plant Pat. No. 9,890) in that the fruit of the new variety ‘Suapri15’ ripens about 3 days before that of ‘Robada’. The skin of the fruit of the new variety ‘Suarpi15’ is smooth compared to bumpy skin for the fruit of ‘Robada’. Further, the fruit of the new variety ‘Suapri15’ has a higher brix at 18% and higher Brix:Acid ratio at 23 compared to about 15% brix and a Brix:Acid ratio of 19 for ‘Robada’.

The fruit of the new variety ‘Suapri15’ ripens about 7 days later than the fruit of ‘Suaprinine’ (U.S. Plant Pat. No. 16,507) and 12 days later than ‘Poppy’ (U.S. Plant Pat. No. 9,593). Further, the fruit of the new variety has a higher brix at 18% compared to 14% for ‘Suaprinine’ and 11% for ‘Poppy’. The fruit of the new variety ‘Suapri15’ has 15% blush where exposed to sunlight compare to no blush for ‘Poppy’.

The new variety ‘Suapri15’ has been shown to maintain its distinguishing characteristics through successive asexual propagations by, for example, cuttings and grafting.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying color photographic illustration shows typical specimens of the foliage and fruit of the apricot variety ‘Suapri15’. The illustration shows the upper and lower surfaces of the leaves and exterior and sectional views of the fruit. The photographic illustration was taken shortly after the fruit was picked and the colors are as nearly true as is reasonably possible in a color representation of this type.
