AndrewAZ I'm not sure of the particular citrus varieties for CUPS growing. I would highly suspect mandarins, satsuma. The varieties that Univ. of Florida are testing inside their screen houses are W. Murcott, Persian lime, Eureka lemon, Meyer lemon, Page orange, Cara Cara navel, Blood orange, Hamlin orange, Valencia orange. Of course one screen house is in Florida for Florida growers, and the other in the central valley of California,which would interested in different cultivars..
