| Abstract: |
A new and distinct variety of plum tree which has the unique combination of desirable features.1. Heavy and regular production of fruit.2. Fruit with large size and attractive dark bluish black skin color.3. Fruit with good flavor and eating quality.4. Nearly uniform size of fruit throughout the tree.5. Vigorous upright growth.6. Good shipping and storage quality of fruit. |
| Claim: |
We claim:
1. A new and distinct variety of plum tree, substantially as illustrated and described, characterized by its large size, vigorous upright growth and being a productive and regularbearer of large, firm, semi-clingstone fruit with good flavor and eating quality; the fruit is further characterized by being nearly globose in shape, with an attractive dark bluish black skin color, having good storage and shipping quality and incomparison to Friar Plum (non-patented) being more round in shape and maturing approximately 30 days earlier. |
| Description: |
ORIGIN OF THE VARIETY
The new and distinct variety of plum tree was originated by us in the experimental orchard located near Modesto, Calif., as an open pollinated seedling of Friar Plum (non-patented). The selection was made from a large group of seedlings growingfrom seed collected from the self sterile Friar Plum tree which was growing among numerous selections of plum trees in our experimental orchard. One such seedling, which is the present variety, being especially desirable with respect to its fruit wasselected for asexual reproduction and commercialization.
ASEXUAL REPRODUCTION OF THE VARIETY
The present new and distinct variety of plum tree was asexually reproduced by budding as performed by us in our experimental orchard located near Modesto, Calif., and shows that all characteristics are established and come true to form throughsucceeding propagations.
SUMMARY OF THE VARIETY
Our new and distinct variety of plum tree is of large size, vigorous upright growth, and a productive and regular bearer of large, firm, semi-clingstone fruit with good flavor and eating quality. The fruit is further characterized by having anattractive dark bluish-black skin color, good storage and shipping quality and in comparison to Friar Plum (non-patented) is more round in shape and matures approximately 30 days earlier.
DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs show reproductions in color of typical specimens of the foliage and fruit of our new plum variety with the upper and lower surface of the leaves being illustrated, an exterior and sectional view of the fruit with afruit divided in the suture plane to reveal flesh coloration and showing a stone remaining in place. The photographic illustrations were taken shortly after being picked at maturity (firm ripe) and the colors are as nearly true as reasonably possible ina color representation of this type.
