Evaluation of Some Domestic and Foreign Walnut Cultivars in the Conditions of Bursa, Turkey
This study was carried out to evaluate some domestic (Bilecik, Mara(s) 12, Mara(s) 18, (S)ebin (S)en1, (S)en 2) and foreign walnut cultivars (Chandler, Fernette, Fernor, Howard, Pedro, Serr) in the conditions of Bursa, northwest Turkey (latitude 40°11 and longitude 29°3) between 2008 and 2012.The cultivars were compared according to leafing time, bloom period of staminate and pistillate flowers, leaf fall, tree vigour and fruit characteristics.The earliest leafing was observed in the cultivar Mara(s) 12 and the latest leafing were noted in Fernette and Fernor.First female flowers appeared at the end of April in the Serr cultivar, while the female flowers in Fernor appeared at the end of May.Catkins flowered between mid-April in Sebin and the end of May in Fernor.Flowering of Sen I and Sen 2 was homogamous, the flowering of Bilecik was protogynous, and other cultivars were protandrous.The earliest leaf fall was observed in Sen1, Sen 2, Sebin, Maras 12 and Maras 18 and the latest leaf fall was seen in Howard, Pedro and Chandler.Sen 1, Bilecik, Chandler Mara(s) 12, Fernor, Pedro exhibited higher vigour than other cultivars.All cultivars produced nuts in 2012.The fruit weight of cultivars ranged between 9.86 g (Mara(s) 12) and 16.80 g ((S)en 1).The shell thickness varied between 1.62 mm (Sen I) and 2.67 mm (Howard).The percent kernel was highest in Sebin(57.22%).
