| 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 in late June, with first picking on Jun. 24, 1999. The fruit is uniformly large in size, subacidic 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 an unnamed white flesh nectarine as the selected seed parent and Ruby Diamond (U.S. Plant Pat. No. 7,918) as the selected pollen parent. |
| Claim: |
I claim:
1. A new and distinct variety of nectarine tree, substantially as illustrated and desribed, that is most similar to Spring Sweet (U.S. Plant Pat. No. 9,962) nectarine, by producingfruit that is full red in skin color, yellow in flesh color, subacidic in flavor, clingstone in type and firm in texture, but is distinguished therefrom and an improvement thereon by producing fruit that is sweeter in flavor, that is larger in size andthat ripens 7 days earlier. |
| 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 ofnectarine tree (Prunus persica), which has been denominated varietally as `JUNE CANDY`. 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 orchardat Bradford Farms near Le Grand, Calif. in Merced County (San Joaquin Valley). It was developed as a first generation cross using an unnamed white flesh nectarine as the selected seed parent and Ruby Diamond (U.S. Plant Pat. No. 7,918) as theselected pollen parent. Subsequent to origination of the present variety of nectrine tree, I asexually reproduced it by budding and grafting, in the experimental orchard described above, and such reproduction of plant and fruit characteristics were trueto 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 Spring Sweet (U.S. Plant Pat. No. 9,962) nectarine, by producing fruit that is full red in skin color, yellow in flesh color, subacidic in flavor, clingstone in type and firm in texture, but isdistinguished therefrom and an improvement thereon by producing fruit that is sweeter in flavor, that is larger in size and that ripens seven days earlier.
The present variety is similar to its seed parent, Ruby Diamond (U.S. Plant Pat. No. 8,923) nectarine, by producing firm, full red, yellow flesh nectarines, but is very distinguished therefrom by producing fruit that is clingstone instead offreestone in type, that is subacidic instead of acidic in flavor, and that ripens about 15 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.
POMOLOGICALCHARACTERISTICS
Referring now more specifically to the pomological characteristics of this new and distinct variety of nectarine tree, the following has been observed of a 5 year-old tree grown under the ecological conditions prevailing near Le Grand, MercedCounty (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 codedesignations are by reference to the Inter-Society Color Council National Bureau of Standards. Common color names are also used occasionally.
