Upon approval of the grant, work began March 1, 2016. Substantial research was initiated for the project.
Upon determination that tissue culture labs are cost prohibitive, several tissue culture labs were contacted. One tissue culture lab was able to produce three varieties of Certified Virus and Disease free hop plants.
Great Lakes Hydrogrow was created for the research and development phase of Virus and Disease Free Hop Plant Production. Our website http://www.greatlakeshydrogrow.com/ was produced to disseminate information about this project.
We began to study the process of tissue culture and what is required to be successful using this method. We studied the uses of tissue culture in hop plant production. We reviewed the status of current research being completed. We researched the feasibility of using tissue culture to produce disease free Hop plants.
As a result of our research we located a project using tissue cultures for Hop plant production:
‘Addendum A’ The Elimination Of Viruses And Hop Latent Viroid From Hop In Poland. ‘2005’

Hops in Poland are commonly infected with Hop latent viroid (HLVd) and viruses: Prunus necrotic ringspot virus (PNRSV) and Hop mosaic virus (HpMV). Previous experiments were successful in obtaining virus-free hop plants by heat therapy method but appeared to be inefficient for HLVd elimination. In these studies virus and viroid free hop plants were obtained by meristem-tip culture. The meristem tips were excised from lateral shoot tips of naturally infected plants and placed in vitro. In vitro regeneration ability varied between 0 and 46% of regenerated explants depending upon cultivar, depending upon the time at which meristems tips were obtained. The regenerated plants were tested by ELISA for the presence of viruses and by RT-PCR for the presence of HLVd. Plants with no detectable viruses and HLVd were used for further propagation.
