Apricot tree named ‘Suapriten’

Abstract

A new and distinct apricot, Prunus armeniaca cv. ‘Suapriten’ that ripens early in the season and produces heavy, consistent crops in early districts of the California San Joaquin Valley. Harvest begins about five days after the apricot variety ‘Poppy’ (U.S. Plant Pat. No. 9,593) harvest begins. The fruit is large (averaging approximately 61 mm), firm and develops a bright golden-orange color with red blush on exposed fruit. The flavor has been judged to be superior to other early-season apricots with approximately 15° brix that is well balanced by a slightly tart skin, a slight aroma, and plentiful juice.

Description

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

Variety denomination: ‘Suapriten’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of apricot tree, herein after referred to by the cultivar name ‘Suapriten.’ The new variety ‘Suapriten’ originated by hybridization, and was first hybridized by Bruce Mowrey. The new variety was selected by David Cain and was evaluated by David Cain and Terry Bacon near Wasco, Calif. in Kern County.

SUMMARY OF THE INVENTION

The new variety is characterized by having firm, large fruit (averaging approximately 61 mm in diameter) that develops a bright golden-orange color with red blush on sunlight-exposed fruit. The flavor is superior to other early-season apricots, with approximately 15° brix that is well balanced by a slightly tart skin, a slight aroma, and plentiful juice. The new variety ‘Suapriten’ ripens early in the season and produces heavy, consistent crops in early districts of the California San Joaquin Valley relative to other early apricot varieties. Harvesting of ‘Suapriten’ typically begins in the second week of May in Kern County, Calif., approximately seven days after the beginning of harvesting of the apricot variety ‘Poppy’ (U.S. Plant Pat. No. 9,593).

The seed parent of the new variety ‘Suapriten’ is ‘063-160’ (unpatented) and the pollen parent is ‘90A-006’ (unpatented). The parent varieties were first crossed in 1992, with the date of planting of February 1993, and the time of first flowering being February of 1995. The new apricot variety was first asexually propagated by David Cain near Wasco, Kern County, Calif. in 1997 by budding onto ‘Nemaguard’ (unpatented) rootstock.

The new variety ‘Suapriten’ can be distinguished from its seed parent, ‘063-160’ in that the fruit ripens approximately five days earlier, and is larger and firmer than the fruit of the seed parent. The new variety can be distinguished from its pollen parent, ‘90A-006’ in that the fruit is larger and develops red blush in sunlight while the fruit of the pollen parent ‘90A-006’ does not.

The new apricot variety ‘Suapriten’ may be distinguished from presently available cultivars in commerce by the following combination of characteristics: The new variety most nearly resembles the apricot variety ‘Poppy’ (U.S. Plant Pat. No. 9,593). It may be distinguished from ‘Poppy’ by ripening approximately seven days later, having larger sized fruits (averaging approximately 61 mm in diameter compared with approximately 58 mm in diameter with ‘Poppy’), and having more red blush on exposed fruit.

The new variety ‘Suapriten’ has been shown to maintain its distinguishing characteristics through successive asexual propagations by, for example, budding onto ‘Nemaguard’ rootstock.

BRIEF DESCRIPTION OF THE FIGURE

The accompanying color photographic illustration (FIG. 1) shows typical specimens of the foliage and fruit of the new apricot variety ‘Suapriten.’ The illustration shows the upper and lower surface of the leaves, an exterior and sectional view of a fruit divided across its suture plane to show flesh color, pit cavity and stone remaining in place.

The photographic illustration was taken shortly after being picked (shipping ripe) and the colors are as nearly true as is reasonably possible in a color representation of this type.

DETAILED BOTANICAL DESCRIPTION OF THE INVENTION

Throughout this specification, color names beginning with a small letter signify that the name of that color, as used in common speech is aptly descriptive. Color names beginning with a capital letter designate values based upon The R.H.S. Colour Chart published by The Royal Horticultural Society, London, England.

The new variety ‘Suapriten’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, and light intensity, without, however, any variance in genotype.

The descriptive matter which follows pertains to eight year old ‘Suapriten’ plants grown in the vicinity of Wasco, Kern County, Calif., during 2002 and is believed to apply to plants of the variety grown under similar conditions of soil and climate elsewhere.

TREE
