Roope is a new yellow oat cultivar which was introduced into the National List of Finnish Cultivars in 1996. Roope originates from the 1983 cross Lena / Puhti performed at the former Institute of Plant Breeding, Agricultural Research Centre of Finland in Jokioinen. Puhti is a Finnish oat cultivar and Lena a Norwegian yellow oat cultivar. Breeding work on Roope was carried out at the Institute of Plant Breeding, Agricultural Research Centre in Jokioinen. Following an institutional reorganization, ownership of the cultivar was transferred to Boreal Plant Breeding, Jokioinen. Roope was bred using a modified bulk method. In the 1990 variety trials Roope was tested under the line number Jo 1367. It was further tested in the 1993-1995 Official Variety Trials. In subsequent Official Variety Trials Roope has been tested as a new cultivar. Roope is UPOV-registered cultivar of Finland.

Roope is a rather early, very high-yielding cultivar with rather high protein content and low hull content (Table 1). Roope is presently the highest-yielding oat cultivar in Finland. It has been very productive in different cultivation zones, different soil types and different years. The most exciting characteristic of Roope is a high protein content coupled with a high yield. Roope produces significanty higher groat yields and higher protein yields per hectare than any other oat cultivar in Finland.
