Description

Latin name of the genus and species claimed: Prunus salicina.

Variety denomination: ‘Suplumfortythree’.

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. ‘Suplumfortythree’. The new variety was first hybridized in March 1997 by David W. Cain and selected in August 2000 by Terry Bacon as breeder number: ‘97P040-010-244’. The new variety was first evaluated by Terry Bacon near Wasco, Calif. in Kern County. The variety ‘Suplumfortytfour’ was originated by hybridization.

The new variety ‘Suplumfortythree’ is characterized by red flesh with black skin.

The seed parent is ‘93P-007’ (unpatented), and the pollen parent is ‘90P-055’ (unpatented). The parent varieties were first crossed in March of 1997, with the date of sowing being January 1998, and the date of first flowering being March 1999. The new plum variety ‘Suplumfortythree’ was first asexually propagated by Terry Bacon near Wasco, Kern County, Calif. in January 2002, by budding.

The new variety ‘Suplumfortythree’ is distinguished from its seed parent, ‘93P-007’ (unpatented), in that while both of the varieties ripen at a similar time, ‘93P-007’ has amber flesh compared to red flesh for the new variety.

The new variety ‘Suplumfortythree’ is distinguished from its pollen parent, ‘90P-055’ (unpatented), in that both varieties have red flesh but ‘90P-055’ ripe date is July 1st while the new variety ripe date is August 1st.

The new variety ‘Suplumfortythree’ has a similar ripening time as ‘Friar’ (unpatented), but has red flesh compared to amber flesh for ‘Friar.’

The new variety ‘Suplumfortythree’ has been shown to maintain its distinguishing characteristics through successive asexual propagations by, for example, budding.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying color photographic illustration shows typical specimens of the foliage and fruit of the present new plum variety ‘Suplumfortythree’. The illustration shows the upper and lower surface of the leaves, an exterior and 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.

 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

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, 1986.

The descriptive matter which follows pertains to 13 year old ‘Suplumfortythree’ plants on ‘Nemaguard’ (unpatented) rootstock, grown in the vicinity of Wasco, Kern County, Calif., during 2010, and is believed to apply to plants of the variety grown under similar conditions of soil and climate elsewhere.
