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 (Serbia). 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).
