To determine the possible impact of over-exploitation on the genetic structure of Turkish red pine (Pinus brutia Ten.) populations, three natural and three over-exploited (human degraded) populations of the species in the Mediterranean region of Turkey were investigated with Randomly Amplified Polymorphic DNA (RAPD). With the 80 RAPT) primers tested, 12 of them yielded 137 polymorphic RAPD fragments. Four of the studied populations maintained unique fragments. The mean proportion of polymorphic fragments for all populations ranged from 89.8 to 98.9% and there were no significant differences between natural (94.8%) vs. over-exploited populations (92.7%). The estimated heterozygosity values suggested that Turkish red pine maintains high levels of genetic diversity (range 0.24-0.28) though studied populations and grouped ones as natural (H-e=0.28) vs. over-exploited (0.27) did not differ significantly. The mean F-ST value indicated that the large portion of the total genetic diversity was within populations (93%), but this value was lower in the natural populations (92%) than in the over-exploited ones (94%). In over-exploited populations, excess of homozygosity was observed (about 6% higher) as compared to natural populations, indicating impacts of inbreeding in P. brutia.

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 ...
Determination of esterase enzyme polymorphism in house fly (Musca domestica L.) populations in Turkey TAŞKIN, VATAN; Taskin, Belgin Gocmen; KÜÇÜKAKYÜZ, KÖKSAL; Kence, Meral (2011-01-01) The objective of this study was to determine esterase enzyme polymorphism in 16 natural Musca domestica L. populations from the Aegean and Mediterranean regions of Turkey by using the native polyacrylamide gel electrophoresis (PAGE) technique. The high level of genetic variation among populations and species make esterase enzymes an important tool for analyzing genetic differentiation and evolutionary relationships in insects. In the present study, 22 a-esterase bands were detected by using a-naphthylacetat...
Strong Genetic Control of High Wood Specific Gravity in Young Progenies of Pinus brutia: Potential of Early Selection for Industrial Plantations Yıldırım, Kubilay; Ozturk, H.; Şıklar, Sadi; Balkiz, O. D.; Kaya, Zeki (2011-01-01) To increase quality and amount of wood production in Turkish red pine (Pinus brutia Ten.), genetic control of wood specific gravity (WSG), tracheid length and growth traits was investigated in Ceyhan1A progeny trial by evaluating 168 families originated from six clonal Turkish red pine seed orchards. Wood samples were taken by destructive sampling during the rouging of this trial at the age of seven. Differences among the 168 families for mean WSG was large (ranged from 0.35 to 0.62), as indicated by high i...
GENETIC-STRUCTURE OF MARGINALLY LOCATED PINUS-NIGRA VAR PALLASIANA POPULATIONS IN CENTRAL TURKEY Kaya, Zeki (1994-01-01) To determine the genetic structure of marginally located populations of Pinus nigra var pallasiana, seedlings of open pollinated families from 7 populations were raised in Kizilcahamam nursery near Ankara for 2 years. Seed weight (SW) and cone weight (CW) for families, number of cotyledon per seedling (GOT), timing of bud set in 1990 (BS90) and in 1991 (BS91), bud burst timing of seedlings in 1991 (BB91), height growth in 1991 (HT90) and final height growth in 1991 (HT91) and final diameter growth of seedli...
The Effects of Test Environments on Estimation of Genetic Parameters for Seedling Traits in 2-Year-old Douglas-fir Kaya, Zeki (1992-01-01) The effects of test environments (dry versus wet) on estimation of genetic parameters in seedling traits were studied in 160 open-pollinated families of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) from southwestern Oregon. Seedlings from four populations were grown in two test environments for two growing seasons. Between test environments, -9 bars of water potential difference were created in both growing seasons. Estimated genetic variances in most growth and phenology traits were considerably high...
