| Abstract: |
A plum tree of medium size, upright to spreading, open, foliated with medium size, obovate, medium thick, medium green leaves having a coarsely serrate margin, and alternate, reniform glands positioned on the base of the blade, and a regular and productive bearer of large to medium size, globose, freestone to semi-freestone fruit having deep blue skin with a silvery-grey bloom, and yellow-green, firm to medium texture, crisp, meaty, melting flesh high in sugar content. |
| Claim: |
I claim:
1. A new and distinct variety of plum tree, substantially as illustrated and described, characterized by the bearing of fruit, of best eating quality, which is very high in sugar contentwhereby, for any use, no supplementary sweetening agent is required. |
| Description: |
BACKGROUND OF THE VARIETY
Over a substantial number of years I have engaged in an extensive and continuing plant breeding program at my experimental nursery and orchard located near Le Grand, Merced County, Calif.; one purpose of such program being to provide improvedvarieties of fruit trees. The present variety of plum tree resulted from my endeavors in the conduct of such plant breeding program.
ORIGIN OF THE VARIETY
The present variety of plum tree was originated by me, in my experimental orchard located as aforesaid, as a F.sub.1 cross of the President plum (unpatented) and the Agen (French) prune (unpatented). A large number of seedlings of the abovecross were grown under conditions of careful and continuing observation by me, and--in maturity--one of such seedlings evidenced characteristics which appeared desirable for commercial production. I, therefore, selected such one seedling--and which isthe present variety--for asexual reproduction and with a view toward ultimate commercial introduction of such variety.
ASEXUAL REPRODUCTION OF THE VARIETY
Subsequent to its origination and selection as above, I asexually reproduced the variety in said experimental orchard by top-working on mature orchard trees, and such reproduction ran true, in all respects, to the original seedling tree.
SUMMARY OF THE VARIETY
The present variety of plum tree is of medium size, upright to spreading, open, foliated with medium size, obovate, medium thick, medium green leaves having a coarsely serrate margin, and alternate, reniform glands positioned on the base of theblade, and a regular and productive bearer of large to medium size, globose, freestone to semi-freestone fruit having deep blue skin with a silvery-grey bloom, and yellow-green, firm to medium texture, crisp, meaty, melting flesh high in sugar content.
Further, the present variety of plum tree bears fruit (excellent for prune production) which is of the French--such as Agen--type, but, in comparison, the fruit is larger, less susceptible to growth cracks and rot, and is of a deep blue exteriorcolor.
Additionally, the present variety of plum tree bears fruit which, in comparison to the President, is smaller and not quite as firm, but--with the same good shipping quality--is of better keeping and eating quality.
It will thus be recognized that the present variety of plum tree produces fruit having the desired characteristics for shipping and drying (or other processing), as well as for table or dessert use, fresh or cooked; all without thenecessity--because of the high sugar content of the flesh--of the use of any supplemental sweetening agent.
BRIEF DESCRIPTION OF THE DRAWING
The drawing is a photographic illustration of a twig with leaves, and separate fruit; one of the latter being half cut away to expose the flesh and stone.
