| Abstract: |
The present invention relates to a peach 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 last week in July, with first picking on July 27, 1988. The fruit is white in flesh color, large and uniform in size, freestone in types, firm in texture for good quality storage and shipping, mostly red in skin color, and sweet nonacid in flavor. The variety was discovered as a per-chance seedling occurring near a Babcock (Unpatented) peach tree located adjacent to a commercial May Grand (U.S. Plant Pat. No. 2,794) nectarine orchard. Subsequent to origination of the present variety of peach tree, it was asexually reproduced 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 variety of peach tree, substantially as illustrated and described, which bears whiteflesh freestone fruit that is large and uniform in size, mostly red in skincolor, firm in texture, and which most nearly resembles the Babcock (unpatented) variety, but is distinguished from and an improvement of that variety by bearing fruit that has a higher degree of red skin color, has a smaller stone, matures approximatelytwo weeks later, and is very much firmer and more suitable for long distance shipping by the commercial grower. |
| Description: |
BACKGROUND OF THE VARIETY
The present variety of peach tree, denominated varietally as "Snow Diamond", was discovered by us in 1981 in a cultivated area of an orchard owned at that time by Mitchell Langford and Rose Marie Langford and located at 17047 E. Dinuba Avenue,Reedley, Calif., in the County of Fresno located in the San Joaquin Valley. It resulted as a voluntary seedling that sprouted near a Babcock (unpatented) peach tree adjacent to a commercial nectarine planting of May Grand (U.S. Plant Pat. No. 2,794). Subsequent to the discovery of the present variety of peach 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 present variety most nearly resembles the Babcock (unpatented) peach variety in appearance by producing whiteflesh freestone fruit with excellent flavor and large size, but is distinguished therefrom and an improvement thereon by bearingfruit that harvests approximately two weeks later, has more red skin color, has a smaller stone, and most importantly has much firmer flesh. This high degree of firmness distinguishes the present variety as a commercial long distant shipping whitefleshpeach, which has not heretofore been sufficiently available in supermarkets in the United States.
The differences between the present variety and the May Grand (U.S. Plant Pat. No. 2,794) nectarine are very pronounced, as the present variety is a peach instead of a nectarine, has white flesh instead of yellow flesh, and ripens approximatelyfive weeks later. It is virtually certain that the seed parent of the present variety was the Babcock peach, due to the proximity of the original seedling and its similarity in fruit characteristics. The pollen parent is unknown and its determinationwould be speculative.

POMOLOGICALCHARACTERISTICS
Referring now more specifically to the pomological characteristics of this new and distinct variety of peach tree, the following has been observed under the ecological conditions prevailing near Reedley, Fresno County (San Joaquin Valley),Calif., and was developed at the state of eating ripe on July 29, 1988.
