Abstract: A new and distinct plum tree variety, Prunus salicina, cv. `Suplumforty` is characterized by ripening mid-season. The new variety is further characterized by dark skin and reddish flesh color.
Claim: What is claimed is:

1. A new and distinct plum tree as herein described and illustrated.
Description: Latin name of the genus and speciesclaimed: Prunus salicina.

Variety denomination: `Suplumforty`.


This invention relates to the discovery and asexual propagation of a new and distinct variety of plum, Prunus salicina cv. `Suplumforty`. The new variety was first hybridized in 2002 and selected in July 2004 by Terry Bacon as breeder number:`PL453RB`. The new variety was first evaluated by Terry Bacon near Wasco, Calif. in Kern County. The variety `Suplumforty` was originated by hybridization.

The new variety `Suplumforty` is characterized by ripening mid-season and having dark skin and reddish flesh color.

The seed parent is `Suplumtwentyfour` (the subject of U.S. Plant Pat. No. 13,395), and the pollen parent is an unknown plum in the breeding population. The parent varieties were first crossed in March of 2002, with the date of planting of theprogeny being January 2003, and the date of first flowering being March 2004. The new plum variety `Suplumforty` was first asexually propagated by Terry Bacon near Wasco, Kern County, Calif. in January 2006, by grafting.

The new variety `Suplumforty` is distinguished from its seed parent, `Suplumtwentyfour`, in that the new variety ripens about nineteen days later than `Suplumtwentyfour`.

The new variety `Suplumforty` has a similar harvest time as `Suplumeleven` (U.S. Plant Pat. No. 4,902), but the skin is darker and the flesh is more red in color. The new variety `Suplumforty` has a harvest time seven days after Black Amber(unpatented).

The new variety `Suplumforty` has been shown to maintain its distinguishing characteristics through successive asexual propagations by, for example, budding and grafting.


The accompanying color photographic illustration shows typical specimens of the foliage and fruit of the present new plum variety `Suplumforty`. The illustration shows the upper and lower surface of the leaves, an exterior and sectional view ofa 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 (shipping ripe) and the colors are as nearly true as is reasonably possible in acolor representation of this type.


Throughout this specification, color names beginning with a small letter signify that the name of that color, as used in common speech is aptly descriptive. Color names beginning with a capital letter designate values based upon The R.H.S. Colour Chart published by The Royal Horticultural Society, London, England.

The descriptive matter which follows pertains to 4 year old `Suplumforty` plants on Nemared (unpatented) rootstock, grown in the vicinity of Wasco, Kern County, Calif., during July 2009, and is believed to apply to plants of the variety grownunder similar conditions of soil and climate elsewhere.
