Description:
Genus and species:  Humulus lupulus  L. 
     Variety denomination: ‘Furano 1501U Go’. 
     CROSS REFERENCE TO RELATED APPLICATION 
     The present application claims priority to Japan Plant Variety Protection Application No. 33371, as filed on Sep. 20, 2018, the entire contents are herein incorporated by reference for all the application teaches and discloses. 
     BACKGROUND OF THE NEW PLANT 
     The present invention comprises a new and distinct variety of Hop, botanically known as  Humulus lupulus  L. and hereinafter referred to by the variety name ‘Furano 1501U Go’. ‘Furano 1501U Go’ is a selection from a controlled cross of the proprietary hop female parent ‘Furano Beauty’ and the proprietary male parent ‘070373’. 
     The proprietary female hop line ‘Furano Beauty’ and the proprietary male hop line ‘070373’ were cross-pollinated in 2012 in Kamifurano-cho, Sorachi-gun, Hokkaido, Japan and seeds were obtained. The seeds were sown and plants were grown for evaluation. A plant line was selected in March of 2015 in Kamifurano-cho, Sorachi-gun, Hokkaido, Japan and named ‘Furano 1501U Go’. In 2015, ‘Furano 1501U Go’ was first vegetatively propagated in Kamifurano, Hokkaido, Japan via vegetative cuttings. ‘Furano 1501U Go’ was found to reproduce true to type in successive generations of asexual propagation via vegetative cuttings in Kamifurano, Hokkaido, Japan. 
     SUMMARY 
     The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Kamifurano, Hokkaido, Japan.
         1. Cylindrical to club plant shape;   2. Alpha acid content of 8.3%;   3. Ratio content of beta to alpha of 0.58; and   4. A citrus flavor.
