<pre>Regarding DNA testing and Pendolino - Contact the Adelaide University or
Susan Sweeney at DPSA in Adelaide.

Pendolino is a general purpose pollinator used in Italy, however there
is so much pollen in the Tuscan air and elswhere in major olive
producing areas that confounds the issue. There have been some
experiments showing production changes the further the pollinator isn
away from the test trees.

As olive varieties in broard terms are classified as either self
fertile, partially self infertile or self infertile then understanding
the fertility of variety is important in unravelling the necessity of
planting pollinators. My advice to growers is to include pendollino (10%
of plantings) every 10th row makes it easier to identify the variety
for harvesting. Also 3-4 varieties should be planted which will provide
a wider window of pollination, as well as providing opportunities for
blending and helping control disease. Some varieties show greater
resistance to disease.

Olives Australia are able to give you a list of varieties where the
mother trees have been DNA tested.

Regarding harvesting, the pendolino is more pendulous and so training is
important so that it can be shaken effectively. It will not be a problem
if tou are using pneumatic rakes.
