Abstract

The present invention relates to a nectarine tree, Prunus persica, and more particularly to a new and distinct variety broadly characterized by a medium sized, vigorous, self-fertile, productive and regular bearing tree. The fruit matures under the ecological conditions described approximately the third week in June, with first picking on Jun. 25, 1999. The fruit is uniformly medium in size, acidic and sweet in flavor, globose in shape, clingstone in type, firm and crisp in texture, and fully red in skin color. The variety was a first generation cross using Diamond Ray U.S. Plant Pat. No. (8,948) yellow flesh nectarine as the selected seed parent and an unnamed nectarine seedling as the selected pollen parent.

Description

BACKGROUND OF THE VARIETY
In a continuing effort to improve the quality of fresh market and shipping fruits, I, the inventor, typically hybridize a large number of nectarine and peach seedlings each year. The present invention relates to a new and distinct variety of nectarine tree (Prunus persica), which has been denominated varietally as ‘DIAMOND JUNE’. The present variety was hybridized in 1992, grown as a seedling on its own root in the greenhouse, and transplanted to a cultivated area of my experimental orchard at Bradford Farms near Le Grand, Calif. in Merced County (San Joaquin Valley). It was developed as a first generation cross using Diamond Ray (U.S. Plant Pat. No. 8,948) yellow flesh nectarine as the seed parent and an unnamed nectarine as the selected pollen parent. Subsequent to origination of the present variety of nectarine tree, I asexually reproduced it by budding and grafting, in the experimental orchard described above, and such reproduction of plant and fruit characteristics were true to the original plant in all respects. The reproduction of the variety included the use of Nemaguard Rootstock (unpatented), the standard of the stone fruit industry in central California, upon which the present variety was compatible and true to type.
The present variety is most similar to Sparkling June (U.S. Plant Pat. No. 6,981) nectarine, by producing fruit that is full red in skin color, yellow in flesh color, firm in texture, acidic in flavor and that ripens in mid June during normal years, but is distinguished therefrom and an improvement thereon by having globose instead of reinform glands and by producing fruit that is larger in size and clingstone instead of freestone.
The present variety is similar to its seed parent, Diamond Ray (U.S. Plant Pat. No. 8,948) nectarine, by producing firm, full red, yellow flesh, clingstones nectarines, but is distinguished therefrom by producing fruit that ripens about 16 days earlier.
DRAWING
The accompanying photograph exhibits four whole fruits positioned to display the characteristics of the skin color and form, one fruit divided transversely to the suture plane to reveal the flesh and stone, and typical leaves.
POMOLOGICAL CHARACTERISTICS
Referring now more specifically to the pomological characteristics of this new and distinct variety of nectarine tree, the following has been obeserved of a 5 year-old tree grown under the ecological conditions prevailing near Le Grand, Merced County (San Joaquin Valley), Calif., and was developed at the state of hard shipping ripe on Jun. 28, 1999. However, during 1999 most stone fruit varieties in California ripened approximately ten days later than normal. 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.
