Abstract

A peach tree particularly characterized by its fruit, when fully ripe, having very firm, non-melting flesh which, in most fruit, is completely free of color, the free being further characterized by having large showy blossoms and by bearing clingstone fruit which has superior shipping and keeping qualities, which ripens approximately 20 days earlier than fruit of the Nectar Peach Tree (U.S. Plant Pat. No. 86), and which has an attractive skin coloration.

Description

BACKGROUND OF THE VARIETY

The present invention relates to a new and distinct variety of peach tree broadly characterized by bearing clingstone fruit which has superior shipping and keeping qualities, which is of pleasing flavor and skin coloration, and which has flesh of white or cream coloration, the subject variety being more particularly characterized by its fruit ripening about twenty days earlier than fruit of the Nectar variety (U.S. Plant Pat. No. 86), and by its fruit, when fully ripe, having flesh which is very firm and non-melting and substantially free of coloration. The cultivar name for my new variety is Snowflame.

The Nectar variety of peach tree is well known for its bearing of fruit having a generally white flesh and for its excellent eating qualities and attractive skin coloration. It has been recognized as advantageous to provide a peach tree bearing fruit having the desirable characteristics of fruit of the Nectar variety but having very firm and non-melting flesh which is well suited for canning and having superior shipping and keeping qualities. The flesh of peaches of the Nectar variety is somewhat tinged with pink, especially when fully ripe. However, uniformity in coloration is a characteristic often desired by consumers so that it is advantageous to provide a peach tree bearing fruit with flesh generally free from coloration when fully ripe. In many instances, the time of harvest of peaches greatly influences the price bought on the market, so that it is highly advantageous to provide a variety of peach tree bearing fruit having the desirable eating qualities and general coloration of peaches borne by the Nectar variety, but bearing fruit which ripens substantially earlier when other peaches having those desirable characteristics are not available.

ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY

My new variety of peach tree was originated by me as a part of a continuing plant breeding program in an orchard owned by me and located at 7685 N. Thompson Avenue, near the City of Clovis, in the County of Fresno, and in the State of California. I originated the subject variety by germinating an open pollinated seed from the Nectar variety of peach tree (U.S. Plant Pat. No. 86). When the resulting seedling matured, open pollinated seeds therefrom were, in turn, planted in 1974 and the resulting seedlings grafted by me in 1975 at such orchard onto mature peach trees. The fruit and tree characteristics resulting from grafting such seedlings were carefully observed and the subject variety was selected in 1976 as one tree resulting from such grafting. The selected variety was then propagated by me by further grafting in said orchard, and the tree and fruit characteristics from such grafting proved identical to that of the selected tree.

SUMMARY OF THE NEW VARIETY

The subject variety of peach tree bears clingstone fruit having a white or cream colored flesh and attractive exterior coloration. The subject variety has large, showy blossoms and is particularly characterized by its fruits having flesh which is firm and non-melting and which, in most fruit, is completely free of color. The subject variety is distinguished from the Nectar variety of peach tree (U.S. Plant Pat. No. 86), from which the subject variety is derived, in that the Nectar variety has relatively small, non-showy flowers and relatively softer and melting flesh which is tinged with pink or red. As a result of such very firm flesh, fruit of the subject varity is superior in shipping and keeping qualities to fruit of the Nectar variety and is well suited to canning. The fruit of the subject variety ripens approximately twenty days earlier than fruit of the Nectar variety, but the two varieties of peach tree are similar in being vigorous, in having reinform leaf glands, and in bearing fruit of excellent aroma and eating quality.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying drawing is a color photograph of mature peaches of the subject variety together with a typical twig bearing characteristic leaves, one of the peaches being divided substantially at the suture plane to show the flesh and stone characteristics.
