Genetic variations in some juvenile seedling and one-year-old seedling characteristics of Taurus Fir (Abies cilicica Carr.)

Abstract

In this study, genetic variations in 6 populations from the naturel distribution of Taurus fir totally 150 families (25 of each population) in terms of some juvenile seedling and one-year-old seedlings were examined. The trial was established in Eğirdir Forest Nursery. In this context, genetic and phenotypic correlations, individual and family heritabilities for each character were estimated. The obtained data were evaluated in SAS statistics package programme. According to the results, significant differences were determined both between families within population and among the populations in terms of one year old seedling properties except for epicotyl length. In addition, high and medium level individual and family heritabilities for juvenile seedling and one year old seedling characteristics were estimated. As a result, family selection within the population is more important than selection of population for breeding strategies of the species. Besides, as it showed better performance in terms of all juvenile and one year old seedling properties, Bucak population might be used as a seed source in seedling production in Egirdir Forest Nursery until new and more reliable research results have been acquired.
