Description

Sept. 17, 1974 F. W. ANDERSON PLUM TREE ,Filed Aug. 8. 1973 Plant Pat. 3,617
United States Patent ABSTRACT OF THE DISCLOSURE A plum tree which is large, vigorous, upright to spreading, foliated with large to medium size obovate leaves, and a productive bearer of uniform, large to medium size, globose to slightly oblate, semi-freestone fruit having yellow to red flesh and very deep purple-blue skin.
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 improved varieties 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 nursery and orchard located as aforesaid, as an open-pollinated seedling of the Red Beaut (U. S. Plant Pat. No. 2,539).
Asexual reproduction of the variety: Upon recognition by me of the novel and distinctive characteristics of the present variety of plum tree, I asexually reproduced it by top-working on mature orchard trees in said experimental orchard, and-in maturitysuch reproductions ran true to the parent tree in all respects.
Summary of the variety: The present variety of plum tree is large, vigorous, upright to spreading, foliated with large to medium size obovate leaves, and a productive bearer of uniform, large to medium size, globose to slightly oblate, semi-freestone fruit having yellow to red flesh and very deep purple-blue skin; the varietywhich is generally similar to the Red Beaut-being essentially characterized, as to novelty, by fruit which ripens about ten days before the Santa Rosa (unpatented) and about ten days after the Red Beaut. This permits the harvest of the present variety to start immediately upon the last picking of the Red Beaut and so that the in-market season for such type of plum is desirably extended.
The present variety is further characterized, as to novelty, by fruit which is larger, darker in skin color, and more oblate than the fruit of the Red Beaut.
Brief description of the drawing: The drawing is an illustration, by photographic reproduction in color, of a twig with leaves, and separate fruit one of which is partially cut away to expose the flesh.
