title: Data from: Using partial genotyping to estimate the genetic and maternal determinants of adaptive traits in a progeny trial of Fagus sylvatica

description: Understanding the determinants of phenotypic variation is critical to
 evaluate the ability of traits to evolve in a changing environment. In
 trees, the genetic component of the phenotypic variance is most often
 estimated based on maternal progeny tests. However, the lack of knowledge
 about the paternal relatedness hampers the accurate estimation of additive
 genetic and maternal effects. Here, we investigate how different methods
 accounting for paternal relatedness allow the estimation of heritability
 and maternal determinants of adaptive traits in a natural population of
 Fagus sylvatica L., presenting non-random mating. Twelve potentially
 adaptive functional traits were measured in 60 maternal families in a
 nursery. We genotyped a subset of offspring and of all the potentially
 reproductive adults in the population at 13 microsatellite markers to
 infer paternal relationships and to estimate average relatedness within
 and between maternal families. This relatedness information was then used
 in family and animal models to estimate the components of phenotypic
 variance. All the studied traits displayed significant genetic variance
 and moderate heritability. Maternal effects were detected for the diameter
 increment, stem volume and bud burst. Comparison of family and animal
 models showed that unbalanced mating system led to only slight departures
 from maternal family assumptions in the progeny trial. However, neglecting
 the significant maternal effects led to an overestimation of the
 heritability. Overall, we highlighted the usefulness of relatedness
 pattern analyses using polymorphic molecular markers to accurately analyse
 tree sibling designs.
