| Abstract: |
A plum tree bearing fruit which ripens about one week after the Santa Rosa variety (unpatented) and about one week before the El Dorado variety (unpatented), the fruit of the new variety being globose, having a substantially black and uniform skin coloration, and having flesh of a uniform cream coloration. |
| Claim: |
Having thus described and illustrated my new variety of plum tree, I claim:
1. A new and distinct variety of plum tree as described and illustrated, characterized by bearing clingstone fruit ofrelatively consistently large size and uniformly symmetrical shape and characterized as to novelty by bearing fruit which ripens about one week later than fruit of the Santa Rosa variety of plum tree (unpatented) and about one week before fruit of the ElDorado variety of plum tree (unpatented) and being further characterized as to novelty by bearing fruit during such period which has skin of a uniformly substantially black coloration, and which has flesh of a uniformly substantially creamcoloration. |
| Description: |
BACKGROUND OF THE VARIETY
The present invention relates to a new and distinct variety of plum tree which has been named "Suplumthirteen" for commercial marketing. The new variety is distinguished by bearing fruit which is globose, has a black skin coloration, and hasflesh of cream coloration, fruit of the present variety ripening about one week later than fruit of the Santa Rosa variety (unpatented) and about one week earlier than fruit of the El Dorado variety (unpatented).
The Santa Rosa variety of plum tree is probably the most important variety of plum tree heretofore grown in the San Joaquin Vally of California for commercial and home use. This variety bears fruit of small to medium size having a purplish-redskin coloration and having a flesh coloration which is yellow to dark red. Another important variety of plum tree is the El Dorado, which bears fruit of oblate shape and medium size having amber flesh coloration and reddish-black skin coloration. Fruitof the El Dorado variety ripens about two weeks later than fruit of the Santa Rosa variety. A factor favorably influencing the sale of fresh fruit is unusual, but attractive, skin and flesh coloration. Other such factors are regular shape, uniformityof coloration, and uniformity of shape and size. Therefore, a plum having a uniform, substantially black skin coloration, which has flesh of a contrasting and uniform cream color, and which is substantially uniformly of large size and globose shape, isespecially advantageous.
ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY
The instant variety of plum tree was discovered on June 24, 1979 in a breeding orchard owned by Superior Farming Company, a corporation of the State of Nevada, in the course of a planned breeding program conducted by me for such company. Thisorchard is located at 5090 East Church Avenue, near the City of Fresno, in the County of Fresno, and in the State of Calif. In the breeding program, a plum tree, which was grown from a seedling of unknown variety, was open pollinated and the resultingseedlings planted and observed as they matured into trees and fruited. One of these trees proved advantageous and was selected as the subject variety. This tree was asexually reproduced under my direction in 1979 by budding on seedling rootstock andthe resulting tree proved identical in tree and fruit characteristics to those of such selected tree.
SUMMARY OF THE NEW VARIETY
The instant variety of plum tree is characterized by bearing clingstone fruit of uniformly large size and uniform shape, and the instant variety is particularly characterized by its fruit ripening during a period between the ripening of fruit ofthe Santa Rosa variety and the ripening of fruit of the El Dorado variety and by the fruit of the new variety being globose, by having a skin of uniformly and substantially black coloration, and by having flesh of uniform cream coloration.
BRIEFDESCRIPTION OF THE DRAWING
The accompanying drawing is a color photograph of mature plums of the subject variety together with a typical twig showing characteristic leaves, one of the plums being divided in the suture plane to show the flesh and stone characteristics.
