Abstract

Forking defect is probably the most serious stem-quality problem in BEECH trees.Forking defect greatly reduces wood yield and wood quality. For tree breeding program, it is important to know about the causes of the forking and the genetic component of it.Genetic differentiation of forked and monopodial tree groups is described in seven naturally regenerated, mixed and pure BEECH (FAGUS ORIENTALIS) populations along Hyrcanian forests consisting of seeds of ten forked and monopodial 100 trees (each tree 7 seeds). After testing 6 microsatellite loci originally developed for F. sylvatica, each seed was genotyped at four well-scorable microsatellite loci. Based on the mean genetic distance between seeds of each tree genetic structures were studied.Population differentiation was moderate and differed significantly (Fst=0.13-0.22) among forked and monopodial tree groups. Although, tendency of a strong family structure among seeds of forked and monopodial genotypes is obvious, but the results show that population genetic structures are also influenced by unpredictable factors such as wind direction at a thesis and can be therefore, varied from year to year. It is recommended that seed collections should cover large areas in order to prevent a preponderance of few families and a reduction of the adaptive potential of the next generation.
