PROPERTIES OF FRENCH WALNUT CULTIVARS GROWN UNDER ENVIRONMENTAL CONDITIONS OF THE ČAČAK REGION
- 1. Fruit Research Institute, Čačak, Serbia
Description
In this paper, we have studied major pomo-technological properties and productivity of standard French walnut cultivars (’Marbot’, ’Parisisenne’ and ’Franqete’), newly developed ones (’Fernor’, ’Fernet’) and standard cv. ’Elit’, grown in the region of Čačak. Newly bred cultivars had more favourable vegetation onset, although their fruits were smaller, with lower fruit weight. The average yield per tree ranged from 8.7 kg in ’Elit’ to 13.7 kg in ’Fernete’ (the highest yield was in ’Fernor’, 15.0 kg), i.e. from 870 to 1370 kg (1500 kg/ha). The lowest kernel ratio per tree was in ’Elit’ (4.5 kg, 450 kg) while it was the highest in ’Fernete’ (6.6 kg, 660 kg/ha) and ’Fernor’ (7.4 kg, 740 kg/ha).
