USPP6229P - Peach tree, "Early Maycrest" - Google Patents

Abstract

A new and distinct Peach Tree denominated varietally as "Early Maycrest" generally resembling the Maycrest Peach Tree, U.S. Plant Pat. No. 4,064, but bearing a freestone fruit having a yellow flesh and which is mature for harvesting approximately May 12 through May 16, earlier than that of the Maycrest Peach Tree.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of peach tree, denominated varietally as "Early Maycrest" and which is generally similar in physical characteristics to the "Maycrest" peach tree [U.S. Plant Pat. No. 4,064], of which it is a newly found sport, but from which it is distinguished as to novelty by bearing a more deeply colored fruit having less pubescence than "Maycrest" variety and which ripens for harvesting one week earlier than the Maycrest variety or approximately May 12 through May 16 at Reedley, Calif.

The Maycrest peach tree, [U.S. Plant Pat. No. 4,064], is well known as a vigorous producer of large, firm fleshed and semi-freestone fruit which is ripe for harvesting on approximately May 20 in the San Joaquin Valley of Central California. Furthermore, the fruit of the Maycrest peach tree has long been known for its excellent eating quality and delicious flavor.

It has long been recognized that it would be desirable to have a peach tree that somewhat resembles the Maycrest peach tree but which bears fruit which ripens for harvesting earlier in the season, whereby the commercial demand for large yellow-fleshed peach can be effectively satisfied over a greater period of time.

ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY

The new and distinct variety of peach tree hereof was a chance sport which was discovered on the applicant's property located at 17591 East Huntsman, Reedley, Calif., in March of 1982. The sport which was found in a planting of Maycrest peach trees was noted at that time to have desirable characteristics. Bud wood from this sport was thereafter procured by the applicant and thereafter budded into test trees by Douglas Reisner at the Reisner Nursery located at Visalia, Calif. This first asexual propagation resulted in progeny being produced that were found to possess the same distinctive characteristics as the original sport.

SUMMARY OF THE NEW VARIETY

The "Early Maycrest" variety of peach tree is characterized by many of the desirable characteristics of the Maycrest peach tree [U.S. Plant Pat. No. 4,064], but has the important distinction of bearing fruit that is more deeply colored and has less pubescence than the Maycrest variety and which is ripe for harvesting approximately May 12 through May 16, which is earlier than the Maycrest peach tree. The fruit of the subject invention is freestone in nature having a flesh which is lightly yellow colored with no red in the pit cavity at picking time.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying drawing is a color photograph of five mature fruit of the subject variety, one of which has been divided in the suture plane to show the flesh and pit characteristics; together with a twig bearing representative leaves which display the dorsal and ventral coloration thereof.

DETAILED DESCRIPTION

Referring more particularly to the pomological details of this new and distinctive variety of peach tree the following has been observed under the ecological conditions prevailing at the applicant's orchard located at 17591 East Huntsman Avenue, Reedley, Calif.

Although the new variety of peach tree possesses the desirable characteristics noted under the growing conditions prevailing in Reedley, Calif., in the central part of the San Joaquin Valley, at Reedley, it is to be understood that variations of the usual magnitude and characteristics incident to changes in growing conditions, fertilization, pruning and pest control, are to be expected.

Claims (1)

Having thus described and illustrated my new variety of Peach Tree, what I claim as new and desire to secure by Plant Letters Patent is:

1. A new and distinct variety of peach tree substantially as illustrated and described which is characterized by bearing a freestone fruit having a yellow flesh and by its general resemblance to the Maycrest Peach Tree, U.S. Plant Pat.
