In 2018 and 2019, we made a comparison between walnut seedlings and walnut varieties 'Parisienne' and 'Franquette' in Orehovec in Pišece. We were looking for differences in tree characteristics (trunk size, height and width, growth, habit, sapling growth, bud-breaking time, leaf fall, flowering of male and female blossoms, quantity of male and female blossoms, fruit-bearing type, fertility, fruit ripening, green husk dehiscence, resistance to winter and spring frost and disease resistance) and fruit properties (fruit roundness index, fruit weight, surface area and thickness of the shell, fusion of the shell at the seam, core weight, color and taste of the kernel). The experiment took place on 0.5 ha of surface, on a 39% slope of the terrain. We selected 10 trees. 5 of them were about 30 years old and 5 of them were about 10 years old. In each tree, we observed the properties of the trees and fruits. The characteristics of the fruit were compared with the varieties 'Parisienne' and 'Franquette', which we received from commercial orchard in Kapele near Brežice. We took 20 fruits from each tree, which we used to monitor the parameters and compared them with the reference varieties. We found out that the crop was higher in old seedlings. The fruit and kernel weight of all seedlings was most similar to that of the 'Parisienne' variety. The color of the kernel was mostly yellowish as in the 'Parisienne' variety. The taste of the kernels was better in the fruits of younger seedlings.
