Abstract:
Hazelnut is an important economic tree species, which is loved by people all over the world and is in short supply at present.Its cultivation remains substantially based on named selections from local, wild vegetation. The breeding of excellent varieties is very important in hazelnut industry. However, the research on its chloroplast genome is limited, and the data of interspecific and intraspecific variation are also lacking, which hinders the improvement of breeding. Chloroplast genome as the second largest genetic system in plants after nuclear genome, has an independent evolutionary route and can reveal different evolutionary events at the level of plastome. In this study, we sequenced the chloroplast genomes of three species of hazelnut in Hebei Province. The data offer significant genetic information for the identification of Corylus species, taxonomic and phylogenetic studies, and molecular breeding
