ORIGIN OF THE VARIETY
The present new and distinct variety of plum tree was originated by us in our experimental orchard located near Modesto, Calif., as a first generation seedling from a cross between Wickson plum (non-patented) and a selected seedling with the identification number 3W32LC. The pollen parent with the identification number 3W32LC originated as a selected seedling from seed of an open pollinated Red Beaut Plum (U.S. Plant Pat. No. 2,539). A large group of these first generation seedlings were planted and grown under careful observation by us and during which time we recognized the present variety to be a distinct and desirable tree and to have the fruit characteristics described above. We selected the variety for asexual reproduction and commercialization.
ASEXUAL REPRODUCTION OF THE VARIETY
The present variety of new plum tree was asexually reproduced by budding, as performed by us, in our experimental orchard located near Modesto, Calif., which shows that all characteristics of the tree and its fruit run true to the original form and are established and transmitted through succeeding propagations.
SUMMARY OF THE VARIETY
The present new and distinct variety of plum tree which is of large size, vigorous, upright in growth, and is a regular and productive bearer of large, clingstone fruit with excellent flavor and eating quality. The tree is further characterized by its novelty in producing fruit that is high in soluble solids (average Brix 16.0), is relatively uniform in ripening and will hold firm on the tree for three weeks after maturity (shipping ripe). In comparison to its female parent Wickson plum (non-patented), the tree blooms later in the spring, produces fruit that is sweeter (higher in soluble solids), has the ability to hold its fruit firm on the tree longer and is approximately one month later in maturity.
PHOTOGRAPHS OF THE VARIETY
The accompanying color photographs show typical specimens of the foliage and fruit of our new and distinct plum variety. The upper and lower surface of the leaves are being shown, as well as an exterior and sectional view of the fruit divided in the suture plane to reveal flesh coloration, pit cavity and a stone remaining in place. The photographs were taken shortly after the fruit was picked at maturity (firm ripe) and the colors are as nearly true as is reasonably possible in a color representation of this type.
