Abstract

A new and distinct apricot tree variety characterized by its large, round fruit which exhibits a high external red 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. `Suapriseven`. The variety produces a relatively large, round apricot, having attractive external red blush, and cultivated for the fresh fruit market. It was discovered on May 17, 1990 in Wasco, Kern County, Calif., the new variety being hybridized by Carlos D. Fear, and evaluated and selected 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 of unknown parentage and identified in the breeders' plant collection as seedling F18. 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 `Suapriseven` variety was first propagated by Bruce D. Mowrey in June 1990, in Wasco, Kern County, Calif. by budding onto Nemared rootstock.
The new variety cv. `Suapriseven` may be distinguished from other presently available commercial apricot tree cultivars by the following combination of characteristics: the fruit of the new `Suapriseven` apricot variety ripens early mid-season about with the Katy variety (an unpatented variety) and, thus, is usually eating ripe in Wasco, Calif. about May 18; but the `Suapriseven` fruit can be distinguished from the Katy variety by having a larger size, more external red blush and superior eating quality.
The new variety may be distinguished from its pollen parent, seedling F18, by the following combination of characteristics: the fruit of the `Suapriseven` has a higher external blush, improved apricot flavor and a more rounded, more desirable shape than seedling F18. The new variety may be distinguished from its seed parent, `Suapritwo` by the following combination of characteristics: the `Suapriseven` fruit generally ripens with the `Suapritwo` variety and has nearly the identical appearance and eating quality as that of `Suapritwo`; however, the new `Suapriseven` variety is pollen fertile, whereas `Suapritwo` is pollen sterile and requires a pollenizer. Furthermore, the `Suapriseven` variety exhibits a more consistent bearing habit and is more productive than the `Suapritwo` in years having a low accumulation of winter chilling hours (hours of temperatures between 32° F. and 45° F.). The new `Suapriseven` 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.
