Nectarine tree, Sunecttwelve

A new and distinct variety of nectarine tree generally similar to the Fantasia (unpatented) which it most nearly resembles but from which it is distinguished by producing fruit having a more extensive red skin color, fewer cleft sutures, a rounder shape and brighter ground color.

Description

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of nectarine tree which is generally similar to the Fantasia Nectarine Tree (unpatented), which it most nearly resembles, but which bears fruit having a more substantial amount of red skin coloration, fewer cleft sutures, a rounder shape, and a brighter ground color than that of the Fantasia.

The Fantasia variety of nectarine tree is well known in the industry as a productive bearer of freestone fruit having a bright yellow ground color covered over one-third to two-thirds of its skin surface by a bright red blush. However, despite the success of the Fantasia variety, it is disadvantageous in that the coloring of the skin of the fruit is uneven, and this deficiency is one of the more important factors taken into account by consumers when selecting among varieties in the marketplace. Further, the Fantasia variety suffers the further deficiency of, in some years, bearing fruit having a distinctly pointed apex. Such variability of shape places the Fantasia at a marked disadvantage in commercial competition against varieties ripening at roughly the same time and having a more uniformly round shape.

Thus, it has long been recognized that it would be highly desirable to provide a nectarine tree which bears fruit having a consistently round shape and a highly and evenly colored red skin. Further, it has been known that it would be desirable to have such a nectarine tree whose fruit is of a smoother exterior surface texture, and which exhibits fewer cleft sutures than that of the Fantasia.

ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY

The new variety of nectarine tree was discovered by me in 1978 growing as an open pollinated seedling of a Fantasia Nectarine Tree in an orchard owned by Superior Farming Company of Bakersfield, Calif. and located at 5090 East Church Ave., Fresno, Calif. The variety originated in a planned breeding program conducted by me on the aforementioned property. The seedling was grown to fruiting and was selected by me for propagation at that location.

The new variety was asexually reproduced by budding, that is by inserting buds from the variety into other trees or rootstocks. The buds were forced into growth and eventually produced fruit. Such asexual reproduction was carried out by me and by my assistants under my direction and supervision. The fruit and tree characteristics resulting from this propagation proved identical to those of the original seedling.

SUMMARY OF THE NEW VARIETY

The instant variety of nectarine tree is broadly characterized by perpetuating the general characteristics of the Fantasia Nectarine Tree (unpatented) in the ripening of its fruit and the fruit's general appearance, but is distinguished therefrom as to novelty by the appreciably greater amount of external red skin coloring, the lesser amount of cleft sutures, brighter ground color, by the more globular shape of the fruit, particularly in that the apex is not pointed.

The new nectarine tree bears fruit whose flesh is yellow with a reddish tinge, ripening evenly and having a good eating quality. The flesh is completely freestone, the stone parting from the flesh smoothly. The skin of the fruit has a substantially even coloration, with an attractive red blush color (Plate 40-14) on a bright yellow ground color (Plate 29-6).

BRIEF DESCRIPTION OF THE DRAWING

The accompanying drawing is a color photograph of three mature nectarines of the subject variety, one of which has been divided to show the flesh and stone characteristics, together with a representative twig bearing characteristic leaves.

Although the new variety of nectarine tree possesses the described characteristics as a result of the growing conditions in Fresno County, California, in the central part of the San Joaquin Valley, it is to be understood that variations of the usual magnitude in characteristics incident to growing conditions, fertilization, pruning and pest control are to be expected.

Claims
