This cultivar was registered as a recommended cultivar by the Hokkaido Prefectural Government in 2009 and as Norin Synthetic No.3 of meadow fescue by the Ministry of Agriculture, Forestry and Fisheries in 2010. Source and method of breeding : 'Makibasakae' was developed as a synthetic cultivar using five clones, which were selected from 144 superior clones through evaluation of winter hardiness and a polycross progeny test under frequent cutting. The origins of parental clones were as follows : cl. 387 was derived from 'Bundy', cl. 452 and cl. 455 were derived from 'Salten' and cl. 468 and cl. 473 were derived from 'Boris'. Characteristics : 'Makibasakae' shows remarkably higher winter hardiness with good plant vigor in early spring than 'Harusakae' and 'Pradel' on average in seven locations in the regional performance test, especially in four locations located in eastern Hokkaido with severe winter weather where the soil freezes. 'Makibasakae' is more resistant to snow molds caused by Myriosclerotinia borealis and Typhula ishikariensis than 'Harusakae' and 'Pradel'. The freezing tolerance of 'Makibasakae' is the same level as that of 'Harusakae', though it is higher than that of 'Pradel'. 'Makibasakae' has a 7% higher dry matter yield than that of 'Harusakae' under frequent cutting (about 7-10 cuttings per year) simulating intensive grazing. 'Makibasakae' shows an especially high stable yield in spring and autumn compared to 'Harusakae' and has shown good persistency in the years evaluated. The tolerance to net blotch caused by Drechslera dictyoides of 'Makibasakae' is the same as that of 'Harusakae' and 'Pradel', while the tolerance to halo blight caused by Pseudomonas syringae is slightly weaker than that of 'Harusakae'. The grazing adaptability of 'Makibasakae' is nearly as good as that of 'Harusakae' and the competitive ability of 'Makibasakae' against white clover was slightly higher than that of 'Harusakae' in meadow fescue-white clover mixed sown sward. 'Makibasakae' is an early maturing cultivar as well as 'Harusakae'. The date of ear emergence is one day earlier than that of 'Harusakae' in Sapporo. The forage quality and morphological characteristics of 'Makibasakae' are similar to those of 'Harusakae'. Endophyte was detected in all parental clones of 'Makibasakae'. 'Makibasakae' does not contain two major endophyte alkaloids, ergovaline and lolitrem B, which can be toxic to livestock, but it contains loline alkaloid, which can deter insects. These results indicate that 'Makibasakae' is best suited for use in the management-intensive grazing system in eastern Hokkaido, which has severe winter weather. Seed yield is slightly higher than that of 'Harusakae', and the average seed yield of 'Makibasakae' is 6.3kg/a over a period of three years in Sapporo.}, pages = {1--21}, title = {メドウフェスク新品種「まきばさかえ」の育成とその特性}, volume = {198}, year = {2013}, yomi = {タセ, カズヒロ and タムラ, ケンイチ and サナダ, ヤスハル and タカイ, トモユキ and ヤマダ, トシヒコ and ナカヤマ, サダオ and ダイドウ, ヒサアキ and 水野, カズヒコ and フジイ, ヒロキ and サワダ, ヨシアキ and ヤマカワ, マサアキ and サトウ, ナリチカ and ハヤシ, タク and マキノ, ツカサ} }
