 note = {"Harunemidori," a new cultivar of orchardgrass (Dactylis glomerata L.), was developed by the National Agricultural Research Center for Hokkaido Region and was registered as Norin Synthetic No.10 of orchardgrass by the Ministry of Agriculture, Forestry and Fisheries in 2005. It was also recommended by the Hokkaido Prefectural Government in 2005. Source and method of breeding : "Harunemidori" was developed as a synthetic cultivar using five clones, which were selected from 225 superior clones through evaluation with frequent and infrequent cuttings. The origins of parental clones were as follows : cl 3746, 3747 and cl 3748 were derived from "Hokuiku 50," cl. 3731 was derived from "Hokuiku 45" and cl. 3749 was derived from "Frontier" developed by Snow Brand Seed CO.LTD. Characteristics : "Harunemidori" is an early maturing cultivar as well as "Wasemidori." The average heading date of "Harunemidori" was one day later than that of "Wasemidori" in the regional performance test. "Harunemidori" shows better winter hardiness than "Wasemidori" on average in nine locations in the regional performance test. "Harunemidori" has better snow endurance with good plant vigor in early spring than "Wasemidori" in Hokkaido and northern Tohoku region. "Harunemidori" is more resistant to snow mold caused by Myriosclerotinia borealis than "Wasemidori." "Harunemidori" is resistant to the main leaf diseases such as leaf streak caused by Cercosporidium graminis as well as "Wasemidori." "Harunemidori" is more susceptible to stem rust caused by Puccinia graminis than "Wasemidori." In seven locations in Hokkaido, the average dry matter yield of "Harunemidori" was 3% higher than that of "Wasemidori." In nine locations in the regional performance test, the average dry matter yield of "Harunemidori" at the fourth cut was 7% higher than that of "Wasemidori." "Harunemidori" shows higher performance in autumn as well as in spring than "Wasemidori." Freezing tolerance of "Harunemidori" was the same as that of "Wasemidori," while its fall dormancy was lower than that of "Wasemidori." Its aptitude for grazing is nearly as good as that of "Wasemidori," and it also keeps a good mixture ratio with forage legumes : alfalfa, red clover and white clover as well as "Wasemidori." Forage quality of "Harunemidori" is almost the same as that of "Wasemidori." "Harunemidori" is more erect that "Wasemidori" and has lower plant height at the heading stage. Seed yield of "Harunemidori" is similar to that of "Wasemidori," and the average seed productivity of "Harunemidori" is 7.8kg/a over a period of two years in Sapporo. "Harunemidori" is recommended for use in Hokkaido and the northern Tohoku region. It can be used for haymaking, silage and grazing.},
