Abstract

A new and distinct variety of peach tree which is somewhat remotely similar to the "Summer Lady" peach tree (U.S. Plant Pat. No. 5,865) of which it is a sport, but from which it is distinguished by producing fruit which are mature for harvesting and shipment approximately August 5 to August 20 in the San Joaquin Valley of central California which is of an excellent quality having an exceptional sweet flavor, and a firm flesh.

Description

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of peach tree, which will hereinafter be denominated varietally as the "Pretty Lady" peach tree and, more particularly, to a peach tree which produces freestone fruit which are mature for commercial harvesting and shipment approximately August 5 to August 20 in the San Joaquin Valley of central California.

Due to the market appeal therefor, a premium is placed on varieties of peach trees which produce fruit which is both of high skin coloration and sweet flavor as compared with other commercially available fruit. Where these attributes are present in combination with flesh which is very firm and thus excellently suited to commercial harvesting, packing and shipping practices, the variety may be of unusual value. The new variety of the present invention produces fruit which appears to be of excellent character in all of these respects. In addition, the fruit of the new variety is believed to be well suited to storage for extended periods of time due to the density of the flesh thereof. As such, the new variety of the instant invention appears to possess a very promising commercial potential.

ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY

The present variety of peach tree hereof was discovered by the inventor in 1987 in his orchard which is located in Reedley in the San Joaquin Valley of central California. The variety was discovered as a sport on a single branch located on the westerly side of a "Summer Lady" peach tree (U.S. Plant Pat. No. 5,865) in the orchard approximately 2 meters (6 feet) above ground level. Fruit and stability evaluations were conducted by the inventor in the succeeding years 1988, 1989 and 1990.

The new variety was first asexually reproduced at the inventor's direction in 1991 at Modesto, Calif. using bud grafts from the parent sport. The bud grafts were grafted onto `Nemaguard` rootstock. The resulting asexually reproduced trees of the new variety were planted in 1992 on the inventor's property in Reedley. The inventor has, in succeeding years, observed the asexually reproduced trees of the new variety and confirmed that they are identical in all respects to the parent sport.

SUMMARY OF THE NEW VARIETY

The "Pretty Lady" peach tree is characterized by producing a freestone fruit of very high skin coloration and which are ripe for commercial harvesting and shipment approximately August 5 to August 20 in the San Joaquin Valley of central California. The new variety is most closely similar to the "Summer Lady" peach tree (U.S. Plant Pat. No. 5,865) of which it is a sport, but is distinguishable therefrom by the aforementioned ripening date. The fruit has an exceptionally good, sweet flavor. While the "August Lady" peach tree produces fruit maturing on or approximately August 5 in the San Joaquin Valley of central California, the fruit of the new variety is available for harvest over a much longer harvest period retaining its firmness over this much more extended period. During this extended period of fruit life while the fruit holds on the tree, the fruit retains its shipping and handling firmness and increases daily in fruit size, color and flavor.

DETAILED DESCRIPTION

Referring more specifically to the pomological details of this new and distinct variety of peach tree, the following has been observed under the ecological conditions prevailing at the orchard of origin which is located in Reedley, Calif. All major color code designations are by reference to the Maerz and Paul, A Dictionary of Color, First Edition, 1930, McGraw-Hill Book Co., Inc., New York, N.Y.

Red color extends nearly to the pistil point.

Juice production.--Average -- Distinct, pronounced, not watery.

Flavor.--Well balanced, sweet flavor commonly associated with peach flavor. Slightly acid. To determine soluble solids in the fruit of the new variety, a refractometer was used. Fruit samples were taken from four locations of the tree. Fruit maturation at firm ripe is suitable for harvest and produced Brix readings of 12, 13, 12 and 13, respectively. Four days thereafter, firm ripe fruit from the same four locations produced Brix readings of 13, 14, 13 and 14, respectively. Fruit of the new variety produced tested eleven days after the first test were firm ripe and suitable for commercial harvest. They produced Brix readings of 12, 14, 13 and 14, respectively. Fruit specimens thirteen days after the first test were soft ripe and produced Brix readings of 14, 16, 14 and 16, respectively. All Brix readings were made at the respective orchard sites.

Stone:

Attachment.--Freestone.

Fibers.--Present on ventral edge.

Dorsal edge.--A single groove extending from base of apex. Groove on base to midsection is coarsely lined by ridges on equal sides. Groove from midsection to apex is a single uniform uninterrupted groove line.

Tendency to split.--None observed.

Use: Fresh fruit consumption.

Keeping quality: The fruit of the new variety is noteworthy in that it has high flesh density and retains its firmness over an unusually lengthy period of time when compared with the fruit of other varieties. Refractometer readings appear to indicate that the fruit flesh at a Brix reading of 12 has reached shipping and marketing maturation. Fruit left on the tree eight to eleven days longer has retained a firmness suitable for handling while having gained in size and flavor. The presence of high soluble solids indicates that the fruit will achieve maximum flavor at the market destination. The firmness permits the fruit to be harvested at optimum maturity.

Resistance to disease: The new variety has not been observed to show either unusual susceptibility or resistance to diseases, pests and disorders common to orchards of the central San Joaquin Valley of California.

Harvesting: Fruit harvested by traditional means common to the fruit growing area. Fresh fruit peaches are all hand picked in the orchard.

Shipping and handling qualities: The overall and general observation of this peach selection is favorable and superior in all aspects of growing the trees in the orchard. The cultural maintenance of the orchard is normal and grower friendly. The fruit is firm, colorful and matures evenly over the fruit bearing area. Handling the picked fruit in the conventional manner from the orchard through the packing house has been without special care and with excellent pack outs. The fruit has been transported to markets throughout the United States arriving in excellent condition.

Although the new variety of peach tree possesses the described characteristics noted above as a result of the growing conditions prevailing near Reedley, Calif. in the central part of the San Joaquin Valley of California, it is to be understood that variations of the usual magnitude and characteristics incident to changes in growing conditions, irrigation, fertilization, pruning, pest control, climatic variation and the like are to be expected.

Claims

Having thus described and illustrated my new variety of peach tree, what I claim as new and desire to be secured by Plant Letters Patent is:

1. A new and distinct variety of peach tree substantially as illustrated and described which is somewhat remotely similar to the "Summer Lady" peach tree (U.S. Plant Pat.
