During the years 2001–2004, the yield and morphology of fruit of 4 Belarus varieties of common sea buckhorn: Podarok Sadu, Botaniczeskaja, Otradnaja, Trofimowskaja and the Baltic form that was not a variety obtained from local seeds were investigated in the Experimental Garden of the University of Warmia and Mazury in Olsztyn. The bushes used for the investigation were five years old. On the basis of the conducted tests it was established that the yield, mass, length and width of the fruit of cultivated varieties of common sea buckhorn are related to the individual characteristics and complex of specific climate-soil conditions. The climate – soil conditions of Olsztyn were favorable for development of Belarus varieties of common sea buckhorn. The maximum yield was obtained in 2003 when the highest yields were produced by Otrodnaja variety (20.07 kg per bush) and Podarok Sadu variety (17.07 kg per bush). In 2004 the yields of fruit were the lowest (average for the varieties 1.37 kg per bush).
