'Suika Chukanbohon Nou 1 Go' was selected from the crosses among Red Seeded 3b which sets a high pistillate flower, the Chinese cultivar 'Bei Jing C', and two Japanese cultivars 'Fujihikari TR' and 'Miyako 3 Go'. The proportion of hermaphrodoric flower in 'Suika Chukanbohon Nou 1 Go' is more than two times of the proportion of pistillate flowers in Japanese modern cultivars of 'Ryuhou' and 'Fujihikari TR'. Moreover, 'Suika Chukanbohon Nou 1 Go' bears a higher proportion of hermaphrodoric flowers than Red Seeded 3b, the original breeding material. The pollination period for 'Suika Chukanbohon Nou 1 Go' is shorter than that of normal watermelon cultivars, because the interval of flowering in 'Suika Chukanbohon Nou 1 Go' is short. Consequently, 'Suika Chukanbohon Nou 1 Go' sets fruits intensively in a short time. The trait of high production of hermaphroditic flowers in 'Suika Chukanbohon Nou 1 Go' is polygenic according to the tests on F_1, F_2 and BC _1 derived from 'Suika Chukanbohon Nou 1 Go' and 'Kleckley Sweet' which sets few pistillate flowers. The fruits of 'Suika Chukanbohon Nou 1 Go' are slightly flattened round, green skin for the outer color and red flesh. The brix of the flesh is the same level as 'Miyako 3 Go'. When using 'Suika Chukanbohon Nou 1 Go' as a material for breeding a cultivar with a high female flower-bearing trait, the cultivars or breeding lines with high fruit quality must be used for crossing as parents.}, pages = {101--107}, title = {多両性花性に有する 'すいか中間母本農1号' の育成とその特性}, volume = {8}, year = {2009}, yomi = {スギヤマ, ミツヒロ and スギヤマ, ケイタ and モリシタ, マサミ and オハラ, タカヨシ and サイトウ, タケオ and ヨシダ, タテミ and イワナガ, ヨシヒロ and カンノ, ツグオ and サカタ, ヨシテル} }
