Description

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of peach tree denominated varietally as "September Sun", and more particularly to such a peach tree which bears a full freestone fruit which has a flesh which has a crisp texture and a bright yellow color, and which is further characterized as to novelty by a date of ripening of approximately August 30 through the first week of September and which has a skin of medium thickness which is tenacious to its flesh causing the subject variety to handle and to ship well.

From an economic standpoint, the relative dates of ripening of various varieties of peaches is of extreme importance. It has long been recognized as desirable to provide a peach tree that bears fruit later in the season than other varieties of peach trees which it most nearly resembles whereby the fruit can be sent to market at a time when competition is at a minimum. In addition, if the harvesting periods of various peaches can be effectively spread over a longer period of time, considerable savings and increased efficiency can be attained because the capitol expenditures required to harvest and transport such peaches can be spread over a longer period of time, resulting in lower cost of the final product and increasing the uniformity of production.

The new and distinct subject variety of peach tree is characterized as to novelty by producing a peach which matures for harvesting late in the season, approximately August 30 through the first week of September, at Del Rey, Calif., and in addition has a skin which is medium in thickness, and tenacious to flesh, making this particular peach particularly easy to handle and to ship to market.

ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY

The new and distinct variety of peach tree hereof was a chance seedling which was produced from the applicant's employer's Seed Lot Number 20, which is located in the H. P. Metzler & Sons nursery near Del Rey, Calif. The seed, which was of unknown parentage, was collected from the seedling block Number 20 in the fall of 1978. This chance seedling was then subsequently replanted in the H. P. Metzler & Sons nursery in the early spring of 1979. The new variety of peach tree produced its first fruit in the late summer of 1981. The superior characteristics of the subject variety were observed, recognized and appreciated by the applicant at that time and the seedling was marked for further observation and for asexual reproduction.

The applicant asexually reproduced the subject peach tree by removing budwood from the described chance seedling in the winter of 1981 and rebudding this particular budwood onto test seedlings in the early spring of 1982 in the H. P. Metzler & Sons test block which was located near Del Rey, Calif. This first propogation resulted in progeny being produced that were found to possess the same distinctive characteristics as the original seedling.

Inasmuch as the present variety was a chance seedling, its origin or cross is unknown although it was known by the applicant in the sense that he germinated the seed which produced the original seedling, asexually reproduced the seedling and tested the subject seedling at the designated nursery of the H. P. Metzler & Sons Company, of Del Rey, Calif.
