This paper provides information on the behaviour of Clemenrubi, a new clementine selection introduced from Spain, based on field experiences (including the experiments conducted in 2008-10 in Sicily, Italy, on Carrizo citrange rootstock) and existing literatures. Clemenrubi may be a valid selection for the Italian citrus due to its precocious maturation as early as September, but the sunburn and splitting of its fruits must be controlled. Studies in the coming years will be necessary to determine the behaviour of Clemenrubi in different growing conditions. Some suggestions are given to prevent sunburn and splitting of the fruits, including foliar application of calcium nitrate at 2% in June and July, as well as careful management of irrigation and fertilizer application.
