ABSTRACT:

LATIN NAME OF THE GENUS AND SPECIES OF THE PLANT CLAIMED
Prunus salicina.
VARIETY DENOMINATION
‘Suplumtwentythree’.
BACKGROUND AND SUMMARY OF THE INVENTION
This invention relates to the discovery and asexual propagation of a new variety of plum,
Prunus salicina
cv. ‘Suplumtwentythree’. The new variety was first hybridized by Bruce D. Mowery. The new variety ‘Suplumtwentythree’ was selected and evaluated by David W. Cain near Wasco, Kern County, Calif. The variety was originated by open pollination of an unnamed, unpatented Sun World international breeding plum selection, designated as 91P-001. The new variety is characterized by its early ripening fruit, which ripens evenly and has a mildly sweet taste. The fruit is not prone to fruit drop and has good keeping quality for the fresh market.
‘Suplumtwentythree’ has as its seed parent an unnamed, unpatented plum variety designated as 91P-001. The new plum variety cv. ‘Suplumtwentythree’ arose from an open pollination of the seed parent and thus the pollen parent is an unknown plum variety. The parent varieties were first crossed in 1993, with the date of sowing of November 1993 and first flowering being in 1996. The new ‘Suplumtwentythree’ variety was first asexually propagated by David W. Cain in May 1998, near Wasco, Kern County, Calif., by budding.
‘Suplumtwentythree’ differs from its seed parent, 91P-001, by producing fruits that are slightly larger than its parent, averaging 6.2 cm diameter while 91P-001 averages 5.5 cm diameter. Fruits of the new variety cv. ‘Suplumtwentythree’ have red-colored flesh, while the flesh of 91P-001 is yellow. Moreover, ‘Suplumtwentythree’ ripens approximately four days after its seed parent 91P-001. The new variety ‘Suplumtwentythree’ closely resembles its sibling ‘Suplumtwentytwo,’ but ripens approximately fourteen days after ‘Suplumtwentytwo’.
‘Suplumtwentythree’ most nearly resembles the interspecific tree ‘Flavorosa’ variety (U.S. Plant Pat. No. 10,285). It is distinguished from the ‘Flavorosa’ variety by possessing more rounded elliptic leaves with less pronounced pointed lanceolate apices. The new variety is further differentiated from ‘Flavorosa’ by not being an interspecific hybrid with
Prunus armeniaca
parentage. ‘Suplumtwentythree’ fruits have flesh that tends to be lighter red near the pit cavity when commercially ripe as compared to the darker red coloration near the pit cavity in the ‘Flavorosa variety’. Additionally, the fruits of the new variety are able to hold more tenaciously to the tree, resulting in fruit that is less prone to fruit drop as the fruit approach maturity, in contrast to the ‘Flavorosa’ variety. Fruits of the new variety ripen approximately fourteen days after ‘Flavorosa’.
The flesh of ‘Suplumtwentythree’ fruit is red, in contrast to the yellow flesh of the ‘Black Beaut’ (U.S. Plant Pat. No. 3,617, expired) variety, and ripens approximately 5 days before ‘Black Beaut’. The new plum variety cv. ‘Suplumtwentythree’ ripens approximately 14 days after the ‘Red Beaut’ (U.S. Plant Pat. No. 2,539, expired) variety.
The new plum variety cv. ‘Suplumtwentythree’ has been shown to maintain its distinguishing characteristics through successive asexual propagations by, for example, budding.
