This is a recently developed, proprietary variety of the University of California. Budwood is currently not available from the Repository and Californians interested in obtaining budwood should contact the Citrus Clonal Protection Program. Persons not living in California and interested in obtaining budwood of this variety should contact the developer, Prof Mikeal Roose. According to the developers, 'DaisySL' is an "early/mid-season maturing (early - late December) irradiated selection of 'Daisy'. SImilar in all appearance, quality and production characteristics to 'Daisy' with the exception of seed numbers (1.4 - 2.4 sees/fruit compared to 14 - 20 seeds/fruit for 'Daisy'). Outstanding flavor (13 ? in early December, 15 ? + brix in January). Excellent deep orange rind color with smooth rind texture. Mean fruit size 21. Somewhat difficult to peel. Some tendency as in 'Daisy' for fruit rind detrioration by early February. Some tendency towards splitting and to alternate bear. Performs very well in all climate zones including the desert. Very good production." (Information from M Roose and T WIlliams, 2008)
There have been some reports of seedy limb sports. More information on DaisySL is available here. (RR Krueger, 07/14/2010)
