Stem character, growing period, decease- and insect-resistance, fruit quality, fruit taste, fruit yielding ability, and seed number, weight and color were comparatively observed among 8 raspberry cultivars (Skeena, Haida, Scepter-66,Chilcotin, Meeker, Nootka, Willamette, Golden Queen), 9 blackberry cultivars (Thornless Logan, Boysen, Young-65,Marion, Olallie, Smoothstem-66,Smoothstem-Ta, Comanche-75,Cherokee-79) and one species related to raspberry (Rubus phoenicolasius). Observations were conducted in the experimental field of the Department of Horticulture, Keisen Jogaku-en Junior College, Isehara-city, Kanagawa, Japan for 8 years from 1983 to 1990. Among the raspberries, Meeker, which was determined to be the best, had good fruit quality, high yielding ability and disease- and insect-resistance. Nootka and Willamette followed. Among the blackberries, Boysen was highly rated owing to its extra large fruit size and high yielding ability. Comanche and Cherokee were also rated highly from their good fruit quality, stable high yielding ability and stem erectness. Both of them however had the disadvantage of large spines. Smoothstem-66 and Smoothstem-Ta, which were imported through different routes, were judged to belong different strains. Smoothstem-66 showed the superior fruit quarity, although both of Smoothstems were suitable for the processing use. R. phoenicolasius was recognized to be worthy of a breeding material because of its long lasting fruit quality and the disease- and insect resistance.
