Origin: in East Malling, England, by E. Keep, V.H. Knight, and J.H. Parker, Hort. Res. Intl. Parents are of complex origin; each is from a fourth backcross derivative of the Cumberland black raspberry (Rubus occidentalis) and also has Malling Promise, Malling Landmark, Burnetholm, Pyne' s Royal, Lloyd George, and Norfolk Giant in its ancestry; cross made in 1968; selected in 1973; tested as EM 2467/123; introd. in 1980. Tree: very high yield due to large fruit size and high number of fruit per lateral; tall canes, rather spreading; laterals very long, strong, and well attached, held horizontally; spiny; fruit well exposed. Has genes A1 and A10 conferring resistance to the four known strains of the European aphid vector of the raspberry mosaic virus complex; susceptible to raspberry bushy dwarf virus by graft inoculation and probably by pollen transmission. Fruit: large, blunt conic, very firm; slightly dark and pubescent; fairly easily removed from receptacle; late ripening, up to 2 days earlier than Leo; good, slightly acid fresh flavor; postharvest susceptibility to fruit rots similar to Glen Clova and Malling Jewel; good quality for fresh market and jam making.
