Origine de la variété (obtenteur, origine géographique pour les variétés locales...)
Released from the breeding program of W.R. Okie, USDA-ARS, Byron, GA in 1989. Rubysweet is a Japanese-type plum that resulted from a cross of Mariposa and Methley by V.E. Prince.
Complément d'informations
Pollen shed is moderate and apparently self-incompatible, so Rubysweet should be planted adjacent to other plums blooming at the same time to facilitate insect pollination. In most years, thinning has been required to reduce fruit set.
It blooms with Bruce and Methley, about 2 days before Santa Rosa.
Is well adapted to the humid climate of the southeastern United States.
