| Abstract: |
The present invention relates to a nectarine 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 July, with first picking on Jul. 4, 1990. The fruit is uniformly large in size, excellent in flavor, attractively globose in shape, freestone in type, very firm in texture, and full red in skin color. The variety was developed as a hybridized seedling from the selected seed parent of Red Diamond Nectarine (U.S. Plant Pat. No. 3,165), and an unnamed nectarine seedling as the selected pollen parent. |
| Claim: |
We claim:
1. A new and distinct variety of nectarine tree, substantially as illustrated and described, which is similar to its seed parent, Red Diamond (U.S. Plant Pat. No. 3,165), by producingfreestone nectarines that are full red in skin color and very firm in texture, but is distinguished therefrom and an improvement thereon by producing fruit that ripens 6 days later, is somewhat larger in size, is more globose in shape, and is sweeter inflavor, and by having a large blossom instead of a small blossom, and which is also similar to the Summer Grand Nectarine (U.S. Plant Pat. No. 2,879) by being very productive and by producing freestone nectarines that mature in July, but isdistinguished therefrom and an improvement thereon by producing fruit that ripens 6 days earlier and is full red in skin color over the entire fruit surface. |
| 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 distinctvariety of nectarine tree, which has been denominated varietally as "Ruby Diamond". The present variety was hybridized in 1983 by use 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 Nectarine (U.S. Plant Pat. No. 3,165) as the selected seed parent and an unnamed nectarine seedling as the selected pollen parent. Subsequent to origination of the present variety ofnectarine 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 is similar to that of the Summer Grand Nectarine (U.S. Plant Pat. No. 2,879) by maturing in July, by being very productive, and by being freestone in type, but is distinguished therefrom and animprovemnent thereon by producing fruit that ripens 6 days earlier and is full red in skin color over the entire fruit surface.
The present variety is similar to its selected seed parent, the Red Diamond (U.S. Plant Pat. No. 3,165), in fruit appearance by being a full red colored freestone nectarine with excellent firmness, but is distinguished therefrom and animprovement thereon by producing fruit that ripens 6 days later, is somewhat larger in size, is more globose in shape, and is sweeter in flavor, and by having a large blossom instead of a small blossom.
DRAWING
The accompanying photograph exhibits four whole fruits positioned to display the characteristics of the skin color and form, one fruit divided around 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 under the ecological conditions prevailing near Le Grand, Merced County (San Joaquin Valley),Calif., and was developed at the state of hard eating ripe on Jul. 12, 1990. 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.
