Abstract

A new and distinct plum tree variety, Prunus salicina, cv. ‘Suplumfiftyeight’ is characterized by fruit that is large, with black skin and firm, dark red flesh and ripens early in the season. The fruit of the new variety ‘Suplumfiftyeight’ also has a mildly sweet flavor and a stone that is adherent to the flesh.

Description

Latin name of the genus and species claimed: Prunus salicina.
Variety denomination: ‘SUPLUMFIFTYEIGHT’.
BACKGROUND AND SUMMARY OF THE INVENTION
This application relates to the discovery and asexual propagation of a new and distinct variety of plum tree, Prunus salicina cv. ‘Suplumfiftyeight’. The new variety was first originated by hybridization and identified in July 2012 by Terry A. Bacon as breeder number ‘PL1509RB’.
The seed parent is ‘PL660RB’ (unpatented breeding selection), and the pollen parent is ‘PL729RB’ (unpatented breeding selection). The parent varieties were first crossed in February 2009, with the date of first sowing being February 2010, and the date of first flowering being February 2012. The new plum variety ‘Suplumfiftyeight’ was first asexually propagated by Terry Bacon near Wasco, Kern County, Calif. in February 2013 by dormant grafting.
The new variety ‘Suplumfiftyeight’ is characterized by having fruit that is large, with black skin and dark red flesh and that ripens early in the season. The fruit of the new variety ‘Suplumfiftyeight’ also has firm flesh, a mildly sweet flavor and a stone that is adherent to the flesh.
The new variety ‘Suplumfiftyeight’ resembles its seed parent ‘PL660RB’ (unpatented breeding selection) in that both have fruit with black skin and red flesh. However, the fruit of the new variety ‘Suplumfiftyeight’ begins ripening about 18 days later than the fruit of ‘PL660RB’. Further, the fruit of the new variety ‘Suplumfiftyeight’ has a larger size of about 132 gm compared to about 57 gm for ‘PL660RB’. The flowering time of the new variety ‘Suplumfiftyeight’ starts about 3 days earlier than that of ‘PL660RB’.
The new variety ‘Suplumfiftyeight’ resembles its pollen parent ‘PL729RB’ (unpatented breeding selection) in that both have fruit with black skin and red flesh. However, the fruit of the new variety ‘Suplumfiftyeight’ begins ripening about 5 days later than the fruit of ‘PL729RB’. Further, the fruit of the new variety ‘Suplumfiftyeight’ has a larger size of about 132 gm compared to about 110 gm for ‘PL729RB’. The flowering of the new variety ‘Suplumfiftyeight’ starts at about the same time as that of ‘PL729RB’.
The new variety ‘Suplumfiftyeight’ has black skin and red flesh like ‘Black Splendor’ (unpatented), but the fruit of the new variety ‘Suplumfiftyeight’ begins ripening about 3 days earlier than the fruit of ‘Black Splendor’. Further, the fruit of the new variety ‘Suplumfiftyeight’ has a larger size than the fruit of ‘Black splendor’, at about 132 gm compared to 130 gm for ‘Black Splendor’. The new variety has a brix of 18% compared to 14% for ‘Black Splendor’, and the brix:acid ratio is 32 for the new variety ‘Suplumfiftyeight’ compared to 16 for ‘Black Splendor’. The new variety ‘Suplumfiftyeight’ also has black skin like ‘Black Amber’ (unpatented) and ‘Owen-T’ (unpatented), but the flesh color of the new variety is dark red compared to amber for ‘Black Amber’ and yellow for ‘Owen-T’.
The new variety ‘Suplumfiftyeight’ 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 shows typical specimens of the foliage and fruit of the peach variety ‘Suplumfiftyeight’. The illustration shows the upper and lower surfaces of the leaves and exterior and sectional views of the fruit. The photographic illustration was taken shortly after the fruit was picked and the colors are as nearly true as is reasonably possible in a color representation of this type.
 DETAILED DESCRIPTION
