Abstract

A new and distinct plum tree variety, Prunus salicina, cv. ‘Suplumfiftyone’ is characterized by having large fruit with dark red flesh. The fruit of the new variety ‘Suplumfiftyone’ is also moderately firm, juicy and has a mild sweet flavor. The date of the harvest of the fruit of the new variety is later than for ‘Black Splendor’ (unpatented). The fruit of the new variety ‘Suplumfiftyone’ ripens with nearly same timing as the fruit of ‘Friar’ (unpatented) but has a dark red flesh compared to yellow-colored flesh for the fruit of ‘Friar’.

Description

Latin name of the genus and species claimed: Prunus salicina.
Variety denomination: ‘Suplumfiftyone’.
BACKGROUND AND SUMMARY OF THE INVENTION
This invention relates to the discovery and asexual propagation of a new and distinct variety of plum, Prunus salicina cv. ‘Suplumfiftyone’. The new variety was first originated by hybridization in July 2013 by Terry A. Bacon as breeder number ‘PL1617RB’.
The new variety ‘Suplumfiftyone’ is characterized by having large fruit with dark red flesh. The fruit of the new variety ‘Suplumfiftyone’ is moderately firm, juicy and has a mild sweet flavor.
The seed parent is ‘PL888RB’ (unpatented breeding selection), and the pollen parent is bulk pollen of several midseason plums. The parent varieties were first crossed in February 2010, with the date of first sowing being February 2011, and the date of first flowering being February 2013. The new plum variety ‘Suplumfiftyone’ was first asexually propagated by Terry Bacon near Wasco, Kern County, Calif. in February 2014 by dormant grafting.
The new variety ‘Suplumfiftyone’ is similar to its seed parent ‘PL888RB’ in that both varieties have a red flesh. The new variety ‘Suplumfiftyone’ differs from ‘PL888RB’ in that the fruit of the new variety is larger than the fruit of ‘PL888RB’, at 170 g compared to 129 g for ‘PL888RB’. The fruit of the new variety ‘Suplumfiftyone’ also ripens about 2 weeks earlier than that of ‘PL888RB’.
The fruit of the new variety ‘Suplumfiftyone’ ripens about the same time as the fruit of the variety ‘Friar’ (unpatented), but the fruit of the new variety ‘Suplumfiftyone’ has a red flesh compared to yellow flesh for ‘Friar’. The fruit of the new variety ‘Suplumfiftyone’ has a red flesh that is similar to the flesh of the fruit of the variety ‘Black Splendor’ (unpatented), but the fruit of the new variety ‘Suplumfiftyone’ starts ripening about 43 days later than that of ‘Black Splendor’.
The new variety ‘Suplumfiftyone’ has been shown to maintain its distinguishing characteristics through successive asexual propagations by, for example, cuttings and grafting.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying color photographic illustration FIG. 1 shows typical specimens of the foliage and fruit of the present new plum variety ‘Suplumfiftyone’. The illustration shows the upper and lower surface of the leaves, a view of the fruit as a whole, the stone as a whole, and a sectional view of a fruit divided across its suture plane to show flesh color, pit cavity and the stone remaining in place. The photographic illustration was taken shortly after being picked and the colors are as nearly true as is reasonably possible in a color representation of this type. The photographs depict fruit and vegetative growth from a four year old tree.
 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
