The yield and quality of blanched spears of twenty asparagus cultivars were evaluated in the years 1986-1989. Cultivars originating in Poland, Holland, Germany, France, and in California, USA. All-male cultivars such as Franklim, Lucullus 813 J, and Lucullus 40 as well as dioecious ones such as Limbras 18 and Limbras 22 were among the most suitable for growing in Polish climatic conditions. Less suitable was Mary Washington because of a low yield and thin spears and Eros with a low yield but thick spears. Unsuitable for growing in Poland were UC 72 and UC 800 originating in California, which were late and had the lowest yield. French cultivars, were owing to their earliness, among the best yielding in the first year of harvest but subsequently they gave a lower yield than Dutch and German cultivars. All-male cultivars did not produce thinner spears than did dioecious ones.
