What does "disputed varietal" mean?
Olive trees have been cultivated for centuries and thousands of varieties have been spread around the world. What a Moroccan considers as his native tree may also be considered "native" to an Argentinean, etc. Two different names may actually represent the same varietal. DNA tests can be used to identify separate varieties but the more common method is to send the pit to one of the world experts, such as those at the University of Cordoba, Spain, for identification. The size and shape of the pit is compared to DNA tested standard pits.
