Abstract

The present invention relates to a peach tree and more particularly to a new and distinct variety broadly characterized by a medium size, vigorous, hardy, very productive and regular bearing tree. The fruit matures under the ecological conditions described approximately the last week in June, with first picking on June 27, 1988, making it an early to mid-season ripening peach. The fruit is uniformly large in size, globose in shape, freestone in type, very firm in texture making excellent quality for keeping and shipping, almost full red in skin color at harvest time, and a delicious balance of acid and sugar in flavor. The variety was developed as a hybridized seedling from the selected seed parent, Red Diamond (U.S. Plant Pat. No. 3,165) nectarine, and an unnamed peach seedling as the selected pollen parent.

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, plum, apricot and cherry seedlings each year. The present invention relates to a new and distinct variety of peach tree, which has been denominated varietally as "Diamond 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 Joaquin Valley). It was the result of a seedling using Red Diamond (U.S. Plant Pat. No. 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 most nearly resembles the fruit of Redtop (not patented) by being a freestone peach that ripens in late June, but is distinguished therefrom an an improvement thereon by having a more globose shape, by having almost full red skin color at ripening time and by being extremely firm in texture, making it more desirable to the long distant shipper.
The present variety exhibits desirable characteristics common to its selected seed parent, Red Diamond (U.S. Plant Pat. No. 3,165) nectarine, by producing heavy crops of fruit that are nearly full red in color at harvest time, freestone in type, and very firm in texture, and also that ripens in late June. It noticeably differs from the Red Diamond by being a peach instead of a nectarine and by having a large blossom instead of a small blossom.
DRAWING
The accompanying photograph shows the characteristics of the whole fruit in skin color and form, a characteristic fruit divided on its suture plane showing the flesh and pit cavity, a typical stone, and typical leaves.
POMOLOGICAL CHARACTERISTICS
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 eating ripe on July 5, 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.
