ABSTRACT
Romania is a country where walnut culture has tradition. This fruit crop has good productive potential but it is necessary to grow adequate cultivars in concordance with the ecological conditions and market demands. Lateral bearing walnut cultivars are grown in many countries due to their productivity and precocity. For this reason, cultivar testing program carried out at SCDP Valcea from 1994 was focused also on introduction and evaluation of lateral bearing walnut cultivars from abroad in order to establish the most appropriate Romanian and introduced cultivars to be grown in the sub-Carpathian area of Oltenia. Laterar bearing walnut cultivars proved to be precocius regarding their coming into production, also the yields obtained were up to 40% higher in the case of ’Ferjean’, ’Vina’, ’Hartley’ and ’Lara’ comparatively with ’Franquette’, which was used as control. These cultivars showed higher susceptibility to bacterial blight then ’Franquette’ and Romanian cultivars in the sub-Carpathian area of Oltenia ecological conditions.
