Imperial (VI 684)

Early maturing mandarin. Origin: chance hybrid of Mediterranean or Willowleaf and another mandarin, possibly Emperor in approximately 1890 in Emu Plains, near Sydney, Australia; released by Citrus Clonal Protection Program as VI 684 in 2008. Fruit: medium or small in heavy crop years; yellow orange rind, more intense in regions with cool fall temperatures; generally must be clipped from the tree rather than plucked; skin is thin and soft, and although adherent, peels easily; firm when peeled; good quality; good balance of sugar and acid and good internal color; juice levels at least 35%; granulation sometimes a problem because of the low juice content; usually 4 or fewer seeds per fruit in both solid and mixed plantings; short post-harvest life, 2-4 weeks; de-greening necessary when fruit are harvested early; Brix:acid ratio reaches 7:1 around mid-March in the earliest regions of Australia, with later regions reaching this ratio in early June; ripens extremely early, equivalent to Owari satsuma; can be harvested up to July or August in Australia, depending upon the region. Tree: vigorous and upright.
