Comments	This selection came to Foundation Plant Services prior to 1970 from Harold Olmo at the Department of Viticulture & Enology, University of California, Davis. Ruby Seedless 02 was created by combining material from vines located at B3v13 and B3v14 in the FPS foundation vineyard. Both vines had been heat treated for 91 days. Ruby Seedless underwent microshoot tip tissue culture therapy in 2012 and successfully qualified for the Russell Ranch Foundation Vineyard in 2013.
