Fertility Variation and Effective Number of Parent in a Taurus Cedar (Cedrus libaniA. Rich.) Population

Nasrin Seyedi and Nebi Bilir

Fertility variation and effective number of parent were estimated based on mature cone production in a natural population of Taurus cedar (Cedrus libani A. Rich.). Interactions between cone production and growth characters were also investigated in the present study. Average of number of cones per tree was 57, while there were large differences among individuals within population. The fertility variation estimated proportion of the numbers of cone counted from individuals in the population was 1.52. The effective number or parents was 32.8 (65.6% of census number) in the population. Age, height, diameter at breast height and crown diameter have no significant (p>0.05) effect on cone production. Results of the study were discussed based on silvi cultural and genetic-breeding practices of the species.
