pine (Pinus sylvestris L.) is one of the most common and important
forest tree species in Turkey due to usefulness of its wood to many
commercial uses. This species is classified as one of the economically
important tree species for Turkish Forestry in the “National Tree Breeding
and Seed Production Program”. The objective of the present study was to
investigate variation and inheritance pattern in cone and seed
characteristics of Scots pine and to evaluate variation in cone and seed
characters within and among clones and grafts. The results showed that
maximum CV among the clones was found for SWe (21.95), FS (16.99) and CWe
(16.88). According to the results of SAS, variation between the clones is
averaged at 19.2% and variation within the clones is averaged at 24.4 %.
Variation between the clones ranged from 3.6% (SW) to 34.5% (TC) and
variation within the clones ranged from 12.3% (SW) to 38.1% (WL). For CW, AL,
AW, WW and TC, genetic variation among clones was higher than within clones.
When the results of study like compared with results obtained from natural
populations, it was seen that genetic variability in seed orchard which was
subjected to study was quite low. This case may have dangerous results for
the future of forests.
