Source: Received as trees from the Citrus Clonal Protection Program, 2006.
Parentage/origins: Parents unknown. Donated to J. Semancik, most probably from N. Onelge, A. Cinar, University of Cukurova, Turkey. Supposed to be a selection of Turkish origin.
Rootstocks of accession: Carrizo citrange, Rubidoux trifoliate
Season of ripeness at Riverside: January to March
Notes and observations:
12/2006, RRK: Apparently a selection of C. myrtifolia made in Turkey. The myrtle-leaf group of sour oranges represents a distinctive type. It is currently unclear how the present selection may differ from other myrtle-leaf types in the collection.
Description from The Citrus Industry Vol. 1 (1967):
"Because it somewhat resembles the sour orange, the myrtle-leaf orange (chinotto of Italy, chinois of France) is commonly considered to be a botanical variety of C. aurantium L. Indeed, the presumption is that the myrtle-leaf orange originated as a mutation from the sour orange. The differences are sufficiently great and the degree of variation exhibited so wide, however, as to appear to justify separate species standing.
Availability: Soon to be commercially available in California through the Citrus Clonal Protection Program.
