Advances in Hazelnut Germplasm and Genetic Improvement

Dear Colleagues,

Hazelnut (Corylus spp.) is one of the most important nut crops, having high economic and nutritional value. The Corylus genus is widely distributed across temperate regions of the Northern Hemisphere, with species found in China, Japan, Korea, India, northern Iran, Turkey, the Caucuses, Europe, and North America. To date, 13 species are commonly recognized by taxonomists around the world. The most relevant species in the genus Corylus are European hazelnut (Corylus avellana L.) and its interspecific hybrids, including Ping’ou hybrid hazelnut (C. heterophylla Fisch. × C. avellana L.). This species is diploid, monoecious, wind-pollinated, and has dichogamous and sporophytic incompatibility, bearing edible nuts. Its nuts are widely used in the chocolate, confectionery, and baking industries; moreover, the plant plays relevant ecological functions.

Submissions of original research and review articles from breeders, horticulturists, and researchers are welcome to this Special Issue. Topics of interest include:

• Advances in germplasm investigation, genetic diversity, and phylogenetic evolution;
• Advances in genome/transcriptome sequencing and biotechnology for traits of interest;
• Advances in hazelnut breeding programs and methods and newly released cultivars;
• Advances in genotyping and development of markers for cultivars and genetic population;
• Cultivar phenotyping for potential expansion of hazelnut production to new suitable areas;
• Advances in eco-physiological plant behavior and nutritional value of hazelnuts.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Forests is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
