Abstract
Hazelnut (Corylus avellana L.) is a monoecious, self-incompatible and wind-pollinated species.
This study was carried out to determine the catkin number and pollen germination rate of 19 Turkish cultivars.
In vitro germination was assessed with two methods under two temperature regimes.
Pollen germination was between 8.8 and 65.0% in the medium containing 15% sucrose, 20 ppm boric acid and 0.75% agar among the cultivars while large variation (11.4-72.2%) was observed in hanging drop method.
The cultivar ‘Karafındık’ had the largest number of catkins (3.7 per node) and gave the highest germination rate while ‘Giresun Melezi’ gave the lowest rate.
It is suggested that ‘Karafındık’ has a high pollenizer potential for other cultivars with round shaped nuts.
On the other hand recently registered cultivar ‘Giresun Melezi’ would be considered not good pollenizer due to its low pollen viability.
