Abstract

Introduced walnut cultivars grown as main cultivars in countries with climatic conditions different from Bulgaria, were included in the present study. This evaluation aimed at selecting walnut cultivars with suitable biological and pomological characte­ristics when grown under the climatic conditions of South Bulgaria.The trial demon­strated that the cultivars ‘Fernor’, ‘Lara’ and ‘Tiszacsecsi 83’were later blooming than the other cultivars as ‘Serr’, ‘Hartley’, ‘Izvor 10’ and ‘Sheynovo’. That phe­nological characteristic is very important to avoid spring frost damages. During the period of evaluation the results showed that the yields from the cultivars ‘Izvor 10’, ‘Serr’, ‘Hart­ley’, ‘Fernor’ and ‘Lara’ were higher com­pared to ‘Sheynovo’ and ‘Tiszacsecsi 83’. This is the reason to reco­mmend the first group of walnut cultivars to be grown under the climatic conditions of South Bulgaria.
