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 0.37 to 0.46). Differences between half sib families for WSG were, however, statistically significant. Estimated family heritablity was moderately high (0.38) Genetic correlations between seedling growth traits and WSG were low, but consistently negative. The families with better height and diameter growth had lower WSG values. Also families with late budset and budburst dates in 1991 had lower WSG values. Seedlings originating from northern latitudes had lower WSG than those from southern latitudes. From the results of the study, it seems that early selection of families for WSG (indirect selection for WSG at mature age) would be possible and substantial genetic gain in WSG could be achieved if the selection based on a multi-trait index selection by giving appropriate weights to WSG and other traits. Further implications of early selection for WSG in Anatolian black pine are also discussed in the paper.

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...
Genetic structure of black pine (Pinus nigra ARNOLD subspecies pallasiana) populations sampled from the Bolkar Mountains Tolun, AA; Velioğlu, E; Çengel, Burcu N; Kaya, Zeki (2000-01-01) In order to determine the magnitude and pattern of genetic diversity among Anatolian Black pine (Pinus nigra ARNOLD subspecies pallasiana) populations sampled in Bolkar Mountains and to recommend the potential populations which may be suitable for in situ conservation of genetic resources in this species, isoenzymes from 14 enzyme systems were investigated by starch gel electrophoresis. For this reason, open pollinated seed megagametophytes of half-sib families originated from the four populations (Camliyay...
Genetic variation pattern among Abies cilicica (Pinaceae) populations: Adaptive seed and seedling traits Gülsoy, Ali Murat; Doğan, Musa; Department of Biology (2022-9-12) The pattern of genetic variation in adaptive seed and seedling traits of Abies cilicica was investigated using 160 families from 8 populations representing the species' natural range for two years in the Olcay Forest Nursery in Konya. The study indicated that both populations and families within populations varied significantly in seed and seedling traits. The pattern of genetic variation among populations suggests that there may be a clinal variation concerning altitude and latitude regarding these traits....
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 ...
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...
