Abstract
In China, the total coverage of wild Corylus species is about 1.67 million ha, with 8 species and 2 varieties distributed from northeast to southwest.
Ping hazelnut (C. heterophylla Fisch.) is the most widespread wild species with about 100,000 ha being cultivated for nut production.
Cultivars of Ping-ou hybrid hazelnut, from crosses of the Ping hazelnut and the European hazelnut, are now widely cultivated for commercial production.
The total area of the plantings is about 112,000 ha in China, most of which are young or just starting to bear nuts.
In order to make a comprehensive introduction of hazelnut production in China to experts in this field from all over the world, the authors summarize the current situation on hazelnut production based on years of accumulated research data, literature review, and information collected from other hazelnut research units.
In this review, the status of wild species, cultivars and cultivation of Ping-ou hazelnuts, problems and prospects will be summarized in detail.
The status and problems in orchard management, such as orchard design, cultivar selection, pollination, training and pruning, plant propagation, diseases and pest control, harvest and storage will be introduced.
Postharvest processing and the present processed products will also be mentioned although that aspect is just at the primary stage of development in China.
New policies about hazelnut, new breeding projects and regional trials aiming to select cultivars with cold hardiness, branch shriveling resistance, high catkin retention and compatible pollinizers are presented for evaluating the prospects of hazelnut production in China in the near future.
