“…This values were between 92 and 99.5%. It was found that pellicle removal was 92.54% (Ko¨ksal andOkay 1997), 76-100% (Demir andBeyhan 2000), 38-70% (Monastra et al 1997), 50% (Mehlenbacher and Miller 1989), 71-100% among selected clones in four cultivars ( _ I Islam 2000). These values show that the percentage pellicle removal of the selected types is higher.…”

Clonal selection was practised in ‘Uzunmusa’ hazelnut over the past 3 years (1999‐2001) to select the highest quality types. Based on an initial assessment of a total of 102 types, 45 were selected for further study. The best types were selection numbers (SN) 397 and 570. The two selected clones have very good characteristics and seem to be superior to the standard clone. The clones had a higher kernel percentage (62.72%), a higher number of nuts per cluster (5.5), thinner shells (0.75 mm) and heavier nuts (2.34 g). On the other hand, the clones seem to be very suitable for the nut industry because of their oil content and size. These types have very thin shells which are suitable for in‐shell market.

“…The conservation of local cultivars is essential for breeders and stakeholders [33,34] and their micropropagation is a suitable tool for the production of true-to-type and diseasefree plants. Micropropagation of hazelnut cultivars has been described in several studies [35][36][37][38][39][40] and it is commonly used in the USA, Chile, and Italy as a tool for propagation and conservation of genetic resources [33,41].…”

Cryopreservation by droplet vitrification was applied to hazelnut (Corylus avellana L.). axillary buds of the Italian cultivated variety Tonda Gentile Romana, which were collected from in vitro growing shoots, immersed in ice cooled PVS2 or PVS3 for 60 or 90 min, then transferred to a droplet of vitrification solution, placed on a strip of aluminium foil, and plunged into liquid nitrogen (LN). Additionally, the effect on the recovery of the mother plant after cryopreservation was evaluated, following a cold pre-treatment at 4 °C for 3 months. The highest regrowth percentage (56.7%) was obtained after applying PVS3 for 60 min, while the application of PVS2 for the same amount of time reduced regrowth to 41.5%. Increasing the exposure to vitrification solutions to 90 min reduced regrowth to 43.3% when PVS3 was applied, and 35.6% if PVS2 was used. The cold pre-treatment on the mother plant did not significantly improve overall regrowth. The cryopreservation process did not decline the rooting ability of the recovered shoots.
