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.
