ORUS 1839 (Fallred ORUS 1347) × ORUS 1835 (PI 338908 × Heritage) (PI 338908 is East Malling selection 791/45 derived from Malling Landmark and Rubus occidentalis); tested as ORUS 2036; introd. in 1984. Tree: moderate yield, slightly less than Heritage over the entire season; primocanes vigorous, glabrous, nonwax green with purple overlay; scattered pale purple spines that are objectionable; fruiting laterals medium to short length. Some resistance to root rot; susceptible to infection by pollen transmission of raspberry bushy dwarf virus and to the common strain of the North American aphid vector of the raspberry mosaic virus complex. Fruit: medium size, uniform shape; very firm; fairly dark red; ease of separation from receptacle varies and can be rather difficult under cooler weather conditions; good fresh-market and processing qualities; fruit produced on primocanes in August; ripens up to 7 days earlier than Heritage in the Pacific Northwest.
