Notes
Budwood from a nucellar Ruby Red source was irradiated in 1963, and one of the products found in 1971 was a darker pigmented grapefruit designated A&I 1-48. This was never released commercially, but a budsport from it producing fruit almost as red as Star Ruby was found in 1976, and released as Rio Red in 1984.
