Abstract

Scots 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.
