Abstract

The present invention relates to a nectarine tree, Prunus persica, and more particularly to a new and distinct variety broadly characterized by a large size, vigorous, self-fertile, productive and regular bearing tree. The fruit matures under the ecological conditions described approximately the third week in August, with first picking on Aug. 17, 1988. The fruit is uniformly large in size, acidic in flavor, globose in shape, clingstone in type, very firm and crispy in texture, and nearly full red in skin color. The vriety was discovered as a mutation of one of the three main scaffolds of an `August Red` (U.S. Plant Pat. No. 6, 363) nectarine tree in a commercial orchard.

Description

BACKGROUND OF THE VARIETY
We, the discoverers, are commercial stone fruit growers at Waldner Farms near Dinuba, Calf. in Tulare County (San Joaquin Valley). In 1988 we planted a 10 acre orchard of `August Red` (U.S. Plant Pat. No. 6,363) nectarines in a cultivated area of our property. In 1993 we discovered a tree in that orchard having an apparent mutation on one of its three main scaffolds. All of the fruit on this scaffold ripened about 1 week earlier than the fruit on the other two scaffolds. The fruit on the mutated limb was virtually one hundred percent red, while the fuit on the other two scaffolds reached only about fifty percent red at full maturity. Subsequent to the discovery of this mutated scaffold, we asexually reproduced it by budding and grafting on Nemaguard rootstock. Also, we grafted scions from the mutated scaffold and `August Red`, side by side, onto a Nemaguard rootstock to substantiate its uniqueness from the `August Red`. The reproduction of plant and fruit characteristics of this newly discovered nectarine variety proved true to the original mutated scaffold in all respects. Also, one of the inventors of the `August Red`, Lowell Bradford, inspected the original mutated limb and the multiplied trees and acknowledged its uniqueness from the `August Red`. In accordoance with our observations for 5 years, we have demonstrated that the present discovery relates to a new and distinct variety of nectarine tree, which has been denominated varietally as `AUGUST FIRE`.
The present variety is most similar to the `August Red` nectarine tree by having a similar tree in size, vigor, and productivity and by producing large clingstone nectarines that are acidic in flavor, very firm in texture, and that ripen in August, but is distinguished therefrom and an improvement thereon by producing fruit that ripens about 7 days earlier and that has a much higher percent of red skin color over the surface area.
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
