Abstract: The present invention relates to a peach tree and more particularly to a new and distinct variety broadly characterized by a large size, vigorous, hardy, productive and regular bearing tree. The fruit matures under the ecological conditions described approximately the first week in June, with first picking on June 3, 1988. The fruit is uniformly large in size, good in flavor, attractively oblate in shape, clingstone in type, very firm in texture making excellent quality for keeping and shipping, and almost full red in skin color at harvest time. The variety was developed as a hybridized seedling from the selected seed parent, Red Diamond (U.S. Pat. No. P.P. 3,165) nectarine, and an unnamed peach seedling as the selected pollen parent.
Claim: We claim:

1. A new and distinct early ripening variety of clingstone peach tree, substantially as illustrated and described, which most nearly resembles the Merrill Gemfree (U.S. Pat. No. P.P. 1,409) peach variety by producing fruit that matures at nearly the same time, but is distinguished from and an improvement on that variety by having almost full red skin color at ripening time, by being extremely firm and non-melting in texture, by beingclingstone in type, and by having a more desirable oblate shape.
Description: BACKGROUND OF THE VARIETY

In a continuing effort to improve the quality of shipping fruits, we, the inventors, typically hybridize a large number of nectarine, peach, plug, apricot, and cherry seedlings each year. The present invention relates to a new and distinctvariety of peach tree, which has been denominated varietally as "Crown Princess". The present variety was hybridized in 1984 by us in a cultivated area of our experimental orchard at Bradford Farms near Le Grand, Calif. in Merced County (San JoaquinValley). It was the result of a seedling using Red Diamond (U.S. Pat. No. P.P. 3,165) nectarine as the selected seed parent and an unnamed peach seedling as the selected pollen parent. Subsequent to origination of the present variety of peach tree,we asexually reproduced it by budding and grafting, and such reproduction of plant and fruit characteristics were true to the original plant in all respects.

The fruit produced by the present variety matures at nearly the same time as that of Merrill Gemfree (U.S. Pat. No. P.P. 1,409) peach, but is distinguished therefrom and an improvement thereon by having almost full red skin color at ripeningtime, by being extremely firm and non-melting in texture, by being clingstone in type, and by having a more desirable oblate shape.

The present invention exhibits desirable characteristics common to its selected seed parent, Red Diamond (U.S. Pat. No. P.P. 3,165) nectarine, by producing fruit that is nearly full red in color at harvest time and very firm in texture. Itnoticeably differs from the Red Diamond by being a peach instead of a nectarine, by being clingstone instead of freestone, and by having a large blossom instead of a small blossom.

POMOLOGICALCHARACTERISTICS

Referring now more specifically to the pomological characteristics of this new and distinct variety of peach tree, the following has been observed under the ecological conditions prevailing near Le Grand, Merced County (San Joaquin Valley),Calif., and was developed at the state of shipping ripe on June 3, 1988. All major color code designations are by reference to the Inter-Society Color Council, National Bureau of Standards. Common color names are also used occasionally.
