This M.Sc. thesis entitled Cone Production and Fertility Variation in Brutian Pine (Pinus brutia Ten.) Populations in Acıpayam-Denizli District was carried out to contribute for silvicultural and genetic-breeding practices of the species based on cone production and growth characteristics collected from fifty trees selected phenotypic ally from each three natural populations inSpring of 2013.Averages of two and three years cones were 18.1 and 43.6, respectively while there were large differences among populations and within population based on analysis of variance (p?0.05).The fertility variations were 1.79 for two years and 1.65 for three years cones in polled populations. The effective number of parents were 82.1 (55.9%) for two years and 90.2 (60.5%) for three years cones in polled populations. The relations were changed for the populations and characteristics, while diameter at breast height had positive and significant (p?0.05) effective on cone production in polled populations. Results of the study were discussed for forestry practice and genetic-breeding of the species.
