| Turkey is one of the main walnut producer countries in the world. In 2015, Turkey ranked fourth in world production with 180,807 tons of production. It can be said that main part of walnut trees in Turkey have been grown without using of pesticides and chemical fertilizers, so that production shows organic qualifications. Continuous seed propagation in Turkey has given rise to a great number of seedling walnut trees, which represent valuable walnut gene resources. The number of native trees is estimated to be over 9 million and they possess large genetic variability in yield, nut and kernel characteristics, late bud breaking, late flowering, winter hardiness, tolerance to diseases. Thousands of walnut trees had been cut down in the eastern part of Turkey and sold abroad after the 1980’s. After recognition of the importance of propagation by grafting and budding by growers in recent years, the orchards are being established with standard cultivars. These standard walnut orchards are generally established with Californian and French cultivars. The Ministry of Food, Agriculture and Livestock and The Ministry of Forestry and Water Affairs of Turkish Republic have important new policy on walnut development program in Turkey. The most important climate restrictions for walnut production are spring frosts in Turkey. Turkish walnut breeding program is abounding with cultivar breeding. There are no adequate studies on rootstock breeding. Harvesting cannot be made mechanically because native trees are large in size. Turkey’s walnut production is expected to increase about 40,000 tons in the next 10 years with the initiation of production from newly … |
