A peach tree, denominated "Ryans Sun," producing freestone fruit having a dark red color with bright yellow flesh of very firm and crisp character and a skin which is tenacious to the flesh ripening in the last week of August.

Description

BACKGROUND OF THE VARIETY

The present invention relates to a new and distinct variety of peach tree, denominated "Ryans Sun," broadly characterized by its full freestone fruit having a dark red color with bright yellow flesh and more particularly to such a peach tree wherein the fruit has very firm and crisp flesh with a skin which is tenacious to the flesh and which ripens for picking in the last week of August after the patented O'Henry peach in the San Joaquin Valley of California.

The commercial market for fresh fruit is dependent to a large degree upon varieties which produce fruit possessing those characteristics allowing the fruit to withstand the rigors of picking, packing and shipping without appreciable damage in appearance or quality. Since such fruit must frequently be shipped great distances under conditions such as to cause substantial deterioration in fruit of the less hardy varieties, a major share of the commercial market is composed of the more durable varieties. The commercial value of such fruit is enhanced where it is of high color and reaches maturity late in the season. The O'Henry peach tree (U.S. Plant Pat. No. 2,964) has good qualities in many of these respects. The variety of the present invention produces fruit of very good shipping quality in that its flesh is very firm and crisp with a skin which is tenacious to the flesh thereby resisting damage in handling and shipping. The fruit is further characterized by its deep red color which provides an attractive and appealing appearance enhancing its commercial value. The fruit is still further characterized by its ripening time which is after the O'Henry peach. Thus, the fruit of the instant variety possesses many of the best commercial attributes of the O'Henry peach, but is distinct therefrom, among other respects in ripening after the O'Henry peach.

ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY

The instant new variety of peach tree was discovered by myself in 1976 and is a newly found seedling of the patented O'Henry peach tree. Seeds of the O'Henry peach tree were planted in a plot in the nursery of H. P. Metzler & Sons, Inc. at 5286 South Del Rey Avenue, Del Rey, Calif. 93616 in 1973 and 1974. The first fruit of the present variety was observed in 1976 and its distinctive characteristics discovered at that time. The present variety was asexually propagated under my direction at H. P. Metzler & Sons, Inc. in 1978 by collecting buds of the newly found seedling and budding a number of trees with these buds. In 1979, trees of this new variety were planted in a test block on Ranch No. 18 of H. P. Metzler & Sons, Inc. at Del Rey, Calif. Trees of the new variety were observed in the test block over several growing seasons and the fruit and tree characteristics resulting from such asexual reproduction proved to be identical to those of the original seedling of the new variety.

SUMMARY OF THE NEW VARIETY

The instant variety of peach tree is characterized by its full freestone fruit having a dark red color with bright yellow flesh of a very firm and crisp character and skin which is tenacious to the flesh, a tight pit cavity bounded by flesh of red coloration and ripening in the last week of August.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying drawing is a color photograph of five mature fruit of the instant variety, one positioned to show the side, a second positioned to show the stem, a third positioned to show the apex, a fourth sliced along the suture plane with the pit left in place and a fifth sliced along the suture plane with the pit removed to expose the pit cavity. A representative twig is also shown in the photograph with characteristic leaves.
