| Abstract: |
The present invention relates to a nectarine tree and more particularly to a new and distinct variety broadly characterized by a medium 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 6, 1987. The fruit is of uniform medium size, very firm making excellent quality for keeping and shipping, full red in skin color, and sweet subacid flavor. The variety was developed as the result of a seedling of Red Diamond (U.S. Plant Pat. No. 3,165) as the seed parent and Aurora Grand (U.S. Plant Pat. No. 4,792) as the selected pollen parent. Subsequent to origination of the present variety of nectarine 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. |
| Claim: |
We claim:
1. A new and distinct early ripening variety of freestone nectarine tree, substantially as illustrated and described, which most nearly resembles the May Diamond (U.S. Plant Pat. No.5,454) variety but is distinguished from and an improvement on that variety by ripening seven days earlier, by having a sweeter less acidic flavor, and by blooming more densely the fruit has average size, good flavor, good firmness, and excellent shapefor the commercial grower also, the fruit harvests in California at a very desirable time period, approximately halfway between Early Diamond (U.S. Plant Pat. No. 5,438) and May Diamond (U.S. Plant Pat. No. 5,454). |
| Description: |
BACKGROUND OF THE VARIETY
The present variety of nectarine tree was produced by us at Bradford Farms in Merced County (San Joaquin Valley), Calif., as the result of a seedling of Red Diamond (U.S. Plant Pat. No. 3,165) as the seed parent and Aurora Grand (U.S. PlantPat. No. 4,792) as the selected pollen parent. Subsequent to origination of the present variety of nectarine tree, we asexually reproduced it by budding and grafting, and such reproduction of plant and fruit characteristics were true to the originalplant in all respects.
The present variety most nearly resembles the May Diamond (U.S. Plant Pat. No. 5,454) in appearance by being a full red colored freestone with excellent firmness, but is distinguished therefrom and an improvement thereon by harvesting sevendays earlier. This earlier ripening time fills a very important harvesting time gap between Early Diamod (U.S. Plant Pat. No. 5,438) and May Diamond for commercial nectarines in central California.
The present variety is similar to its seed parent, Red Diamond, by being a full colored firm freestone but is distinguished therefrom by ripening 29 days earlier. The present variety is similar to its pollen parent, Aurora Grand, by being a fullcolored early ripening freestone but is distinguished therefrom by ripening 3 days earlier, by being more uniform in both size and ripening, and by having a recessed apex.
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 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 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 June 10, 1987. 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.
