Fernor – A Perspective Walnut Cultivar under the Conditions of Bulgaria
Keywords:
Juglans regia; new variety; walnutAbstract
The experimen t was carried out at the Fruit Growing Institute – Plovdiv in the period 2009 – 2013 (seven th-eleven th vege-tation period of the walnut tree s). Biological and economic qualities of Fernor cultivar were compared with those of the local cultivars Izvor 10 and Sheynovo. The aim of the investigation was to study the agrobiological characteristics of the Fren en ch walnut cultivar Fernor and to evaluate the possibility of growing it in Bulgaria. The results obtaine ne d show that under the conditions in Bulgaria, the cultivar is moderate in growth, late flowering, with good winter hardine ss, high fertility and resistance to anthracnose (G. leptostyla) and walnut blight (X. arboricola pv. juglandis). Fruits ripen in the first decade of October and their mean weight is 12.4g, the kerne l output is 42.8% and the fat conten t 61.0%. It could be concluded that the cultivar Fernor is suitable to be grown in the country
