Abstract
A new and distinct Citrus cultivar is provided which is capable of forming attractive large pleasantly tasting fruit having a light yellow-orange external coloration. The fruit when compared to that of the ‘Valencia Late’ Sweet Orange Cultivar (non-patented in the United States) is lighter in coloration, generally more flattened, commonly possesses a greater diameter, and peels more readily. Also, the leaves tend to be larger, generally more rounded, and less elongated than those of the ‘Valencia Late’ cultivar. The fruit matures for consumption at approximately the same time as that of the ‘Valencia Late’ cultivar. The new cultivar is well suited for the commercial product of a late-maturing fruit crop.
