Abstract

A new and distinct apricot tree variety characterized by its high productivity and its very large fruit which exhibits an intense red external blush.

Description

BACKGROUND AND SUMMARY OF THE INVENTION

This invention relates to the discovery and asexual propagation of a new variety of hybrid apricot tree, Prunus armeniaca cv. `Suaprieight`. The variety produces a relatively large and very productive apricot, having excellent apricot flavor and an attractive external red blush, and cultivated for the fresh fruit market. It was discovered on Jun. 7, 1990 in Wasco, Kern County, Calif., the new variety being hybridized by Carlos D. Fear, and selected and evaluated by Bruce D. Mowrey and David W. Cain.

The variety has as its seed parent, Apricot tree cv. `Suapritwo` (U.S. Plant Pat. No. 7,550), and its pollen parent is an unnamed, unpatented apricot tree seedling identified in the breeders' plant collection as seedling 066-245, which was derived as an open pollinated seedling of apricot selection S#3. The parent varieties were first crossed in February 1987, and the resulting seed was harvested and sowed in September 1987, with the date of first flowering being February 1990. The new `Suaprieight` variety was first propagated by Bruce D. Mowrey in June 1990, at a ranch near Wasco, Kern County, Calif., by budding on Nemared rootstock.

The new variety cv. `Suaprieigth` may be distinguished from other presently available commercial apricot tree cultivars by the following combination of characteristics: the fruit of the new `Suaprieight` apricot variety is of a very large size and is extremely productive compared with most other commercial apricot varieties; it ripens in the late season about with the Patterson variety (U.S. Plant Pat. No. 2,877) and, thus, is usually eating ripe in Wasco, Calif. about June 7; but the fruit of `Suaprieight` is of a much larger size, better flavor and exhibits a more intense red external blush than the Patterson variety.

The new variety may be distinguished from its pollen parent, seedling 066-245, by the following combination of characteristics: the fruit of the `Suaprieight` ripens later, has lower acidity, a larger size and more rounded shape than seedling 066-245. The new variety may be distinguished from its seed parent, `Suapritwo`, by the following combination of characteristics: the `Suaprieight` fruit outwardly resembles the fruit of the `Suapritwo` variety in size and shape; however, it ripens 10 days later and has a slightly greener ground color. The new variety is further distinguished from `Suapritwo` by being self fertile and much more productive than `Suapritwo` in years having a low accumulation of winter chilling hours (hours of temperatures between 32° F. and 45° F.). The new `Suaprieight` variety has been shown to maintain its distinguishing characteristics through successive asexual propagations by, for example, budding.

BRIEF DESCRIPTION OF THE FIGURE

The accompanying drawing in FIG. 1 illustrates, in full color, a typical stem and mature leaves of the new apricot tree variety, and the outer surface of ripe fruit as viewed perpendicular to the suture line plane and looking at the suture line. The drawing also illustrates the fruit of the new variety sectioned in half from end to end, with the stone removed from the flesh.

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 R.H.S. Colour Chart, published by The Royal Horticultural Society, London, England.
