Abstract:
Oregon pear #9 (OP-9 Bartlett)
was selected in 1956 by the late Dr.
Jess Kienholz from a commercial orchard.
It appeared to him to be better
than other trees in the orchard, and
subsequent nursery trials showed that
trees budded with OP-9 grew faster
than did another 'Bartlett' selection.
Dr.
Kienholz distributed budwood of
OP-9 pear (originally called KPB-1) to several Oregon nurserymen.
In
1961 and 1962 tests at O.S.U. confirmed
that OP-9 grew faster in the
nursery than several other 'Bartlett'
selections.
