Population variability of sweet chestnut (Castanea sativa Mill.) in Croatia according to the fruit morphology
The sweet chestnut (Castanea sativa Mill.) is a noble hardwood providing multiple economic benefits. In Croatia sweet chestnut grows in very diverse ecological conditions, in various forest communities, on an area of about 35, 000 ha. It is spread in two main, split areas in different climate zones. In the last few decades, chestnut blight has been causing the drying and decay of sweet chestnut trees, while its management is significantly influenced by man, which could lead to the loss of genetic diversity. For that reason, the sweet chestnut is on the list of priority species for the conservation of genetic resources. The aim of this study was to accesses the interpopulation and intrapopulation variability of sweet chestnut populations in Croatia according to the morphology of fruits. Nuts were sampled in 14 natural populations, from the whole area of sweet chestnut distribution range in Croatia. Ten morphological traits and four derived ratios were analyzed. Univariate and multivariate statistical techniques were used to evaluate the differences among and within populations. It was concluded that the analyzed morphological traits were very variable. There were significant differences among trees inside populations and among populations for all measured fruit traits. Populations from climatically different and geographically distant habitats, in other words from the Mediterranean and the continental region, differed for three studied characteristics. The research of variability is important for preparation and implementation of measures for the conservation of sweet chestnut genetic resources, whereas the morphological research of fruits is, along with chemical analysis, important as the first step in selecting trees as candidates for future autochthonous best-quality sweet chestnut cultivars.
