Notes and observations
In the late 1980s and early 1990s, six of the twelve selections (Autumn Gold, Barnfield, Chislett, Powell, Rohde, and Summer Gold) evaluated in Australia, were sent to the CCPP for quarantine and then subsequently released for propagation in California in 1991 and 1992. In mid 1990s, an additional selection called Wiffen was also introduced through the CCPP into California. The California Citrus Nursery Society (CCNS) agreed to facilitate the testing of these late navel selections which are currently licensed in California. Evaluations of six of these selections began in California in 1997 at nine locations in collaboration with growers ranging from Madera in the north to Fillmore in the south. (Kahn and Bier 2003). Please see "New late-season navel orange varieties evaluated for quality characteristics" in the bibliography for a complete description of this variety.
