Turkish red pine (Pinus brutia Ten.) is one of the important tree species in Turkey. The species has been heavily disturbed by anthropogenic factors and fire, making it important to understand the magnitude of the impact on genetic diversity of areas reserved for seed production. To explore the extent of genetic variation in Turkish red pine seed stands, a random amplified polymorphic DNA (RAPD) marker system was used in the study. The estimated genic diversity for seed stands was found to range from H=0.17 (P, %of polymorphic loci=%58.7) in Cameli-Goldag to 0.29 (P=%81.7) in Bayramic-Karakoy seed stand though the lowest polymorphism was observed in Findikpinari seed stand (P=55.8%). The total gene diversity was calculated as H-T=0.34, in Turkish red pine. About 65% of the total diversity was within seed stands. No distinct pattern of genetic diversity was found according to the geography, elevation or breeding zones. The highest genetic differentiation was found in the Western Mediterranean geographic region, however, within population genetic diversity was found to be similar among different geographic regions (H-S=0.22-0.24). G(ST) value calculated was high (0.35) indicating that genetic differentiation among the studied seed stands was substantial. Dendrogram constructed with genetic distance data did not yield a firm pattern with respect to geography, elevation and breeding zones. In fact, the most of the clusters in the dendrogram had very low bootstrap values, suggesting that the clusters could be refined if more populations and markers are included in the future studies. The implication of the results with respect to in situ conservation of genetic resources of the species was discussed.

Genetic differentiation between clone collections and natural populations of European black poplar (Populus nigra L.) in turkey
Çiftçi, Asiye; Kucukosmanoglu, Filiz; Karahan, Alptekin; Kaya, Zeki (2017-06-01)
The European black poplar (Populus nigra L.) is an ecologically and economically important tree species for Turkey. The important and major genetic resources of species for future breeding and ex situ conservation purposes have been archived in a clone bank in Ankara by selecting clones from natural populations and old plantations throughout Turkey. There is no study to date assessing genetic composition these materials. Two-hundred-thirty-three P. nigra clones from six geographic region of Turkey (clone co...
Genetic Variation in Cold Hardiness and Phenology Between and Within Turkish Red Pine (Pinus brutia Ten.) Populations: Implications for Seed Transfer
Kandemir, Gaye; Kaya, Zeki; TEMEL, FATİH; Önde, Sertaç (2010-01-01)
Wind-pollinated seeds from 40 trees (half-sib families) were collected from each of six Turkish red pine (Pinus brutia Ten.) populations in southern Turkey. Two-year old seedlings were evaluated for growth, phenology and cold resistance in a common garden experiment established in Ankara, located outside the species' natural range. Each family was represented with a six-tree row plot within each of the three replications. The below freezing temperatures (-15.2 degrees C) observed in January and February of ...
Genetic diversity pattern in Populus Nigra populations of two major river systems in Turkey
Çiftçi, Asiy; Kaya, Zeki; Department of Biology (2019)
European black poplar (Populus nigra L.) is an important tree species in terms of social, economic and ecological interest in Turkey. Although, poplar plantations in large areas meet the needs of the economy, the natural genetic resources of the species have been highly degraded due to anthropogenic effects and natural biological events. To assess genetic diversity structure of natural populations, 124 naturally distributed European black poplar trees from two major rivers (Kızılırmak and Göksu) in Turkey w...
The pattern of genetic variation in shoot growth of Pinus brutia Ten. populations sampled from the Toros mountains in Turkey
Kaya, Zeki (1997-01-01)
The pattern of genetic variation in shoot growth of Turkish red pine (Pinus brutia TEN.) was studied in 180 open-pollinated families from a south to north transect in southern Turkey. Seedlings from 1 coastal, 1 inland and 2 centrally located populations (45 open-pollinated families each) were grown for 2 growing seasons in a forest nursery located near Antalya. The study revealed that both populations and families within populations varied significantly in all seedling traits except for free growth in the ...
Genetic variation in wood specific gravity of half-sib families of Pinus nigra subsp pallasiana tested at the juvenile stage: Implications for early selection
Kaya, Zeki; Temerit, A; Vurdu, H (2003-01-01)
Seeds from 7 populations (total of 281 half-sib families, progeny test) and 35 seed stands (provenance test) representing natural range of Anatolian black pine (Pinus nigra subsp. pallasiana) were sown in a forest nursery in Ankara in 1990 and raised until age 3. Stem wood specific gravity (WSG) of all seedlings was determined at age of 3. The results of this study indicated that WSG did not vary significantly neither among the 7 populations (ranging from 0.41 to 0.42) nor among 35 seed stands (ranging from...
