Title: Viability of Different Pear Pollen and the Effect on Fruit Set of ŽAnjou` Pear (Pyrus communis L.)
Authors: D.O. Ketchie, E.D. Fairchild and F.R. Drake
Abstract:
'Anjou' flowers were hand pollinated from 12
different varieties of pears during 1990, 1991
and 1993. There was a wide range in the bloom
period of the different cultivars. 'Eldorado' and
'Bosc' pollen had the best viability.
Pollen from
'Bartlett' Pyrus calleryana and 'Nijissecki' induced the most fruit set in 1990; however, there
was no difference in 1991 or 1993. By hand
pollinating, no relation was seen between pollen
viability and fruit set.
It is suggested that for
best fruit set in 'Anjou' orchards, hand pollination
should be practiced and/or the orchards should
have at least 3 pollenizer varieties covering
'Anjou' bloom period.
Seed numbers were highest in fruit that had been pollinated with pollen
from 'Old Home' × 'Farmingdale' (OH × F) 333
and OH × F 69. Fruit size was different only in
1991 when the largest was from flowers receiving pollen from 'Nijissecki,' 'Anjou' or OH × F
333. Fruit size was not related to seed number.
No differences were found in quality studies
including firmness, soluble solids, internal color,
external color and titratable acidity which shows
that metaxenia does not exist in 'Anjou' pears.
