| Abstract: |
A plum tree generally similar to the Simka Plum Tree (U.S. Plant Pat. No. 1,882) which it most nearly resembles, bearing large, dark purple fruit, but which ripens about three weeks later than that of Simka, is larger, and is clingstone. |
| Claim: |
Having thus described and illustrated my new variety of plum tree, what I claim as new and desire to secure by Letters Patent is:
1. A new and distinct variety of plum tree substantially asillustrated and described, characterized particularly as to novelty by its general similarity to the Simka Plum Tree (U.S. Plant Pat. No. 1,882) in its regular and productive bearing of large, dark purplish skinned fruit having firm, pale yellow flesh,but differing therefrom in the greater size of its fruit, the ripening of its fruit about three weeks later than that of the Simka, and its flesh which clings over the entire surface of the stone. |
| Description: |
BACKGROUND OF THE NEW VARIETY
The present invention relates to a new and distinct variety of plum tree broadly characterized by its very productive and regular bearing of fruit which is uniformly large and globose in shape, and having a dark purple skin which is tenacious topale yellow flesh, the flesh clinging over the entire surface of the stone. The new variety further is broadly characterized by its general similarly to the Simka Plum Tree (U.S. Plant Pat. No. 1,882), differing therefrom in several importantcharacteristics including the greater size of its fruit and the ripening thereof about three weeks later than that of the Simka.
It has long been recognized that prospective consumers of fruit, and in particular potential purchasers of plums, are influenced in their buying decisions, in large part, by the aesthetic appeal of a given variety. The Simka Plum Tree has longbeen known as a regular bearer of large, rose ebony colored fruit having pale yellow flesh. However, while the Simka has obtained a certain degree of commercial success, it has long been known that it would be desirable to provide a plum broadly similarthereto but which ripens later than the Simka in order to provide a dark-skinned, attractive fruit at a time during the season when few varieties of similarly appearing plums are available. Further, it has long been known that it would be desirable toprovide such a plum having not only an attractive, even exterior coloration but also having an aesthetically pleasing, uniformly globose form with firm, delicately-flavored flesh.
ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY
The new variety of plum tree was discovered by me in 1980 growing as a seedling in an orchard located at 5090 East Church Avenue in Fresno, Calif., and owned by the Superior Farming Company of Bakersfield, Calif. The seedling resulted from aplanned breeding program conducted and supervised by me at the aforementioned location on behalf of Superior Farming Company, and the seed resulted from an open pollination of a flower of a Simka Plum Tree.
I asexually reproduced the new variety in 1980 by budding the variety into other trees or rootstocks located at the above-identified address, and the fruit and tree characteristics resulting from such budding proved identical to those of theoriginal hybrid seedling.
SUMMARY OF THE NEW VARIETY
The instant variety of plum tree is characterized by its general similarity to the Simka Plum Tree (U.S. Plant Pat. No. 1,882), but has the important distinction of ripening approximately three weeks later. Further, the fruit is larger thanthat of Simka and is cling rather than freestone.
The new variety is a very productive and regular bearer of large, globose fruit having evenly colored, dark purplish skin. The fruit of the new variety has pale yellow, firm-textured flesh which ripens evenly with abundant rich juice and adelicate, superior eating flavor. The flesh clings to the stone over the entire surface thereof.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying drawing is a color photograph of three mature plums of the subject variety with one plum divided to show the flesh color and stone characteristics, together with a stone which has been removed from another mature plum and arepresentative twig showing characteristic leaves.
