THE hop is a long-lived dioecious perennial, which produces annual aerial shoots each year from perennial crowns. Space-planted crowns are pruned back annually, and each spring new vines are trained on twines supported from an overhead trellis. The female vines bear papery cone-like inflorescences, which when cured constitute the hops of commerce. New yards and vacant spaces in old yards are planted with rhizome sections obtained from established crowns. All plants of a single variety would be the same genetically, barring the occurrence of somatic changes or the establishment of chance seedlings. Any variation among plants then would be due to somatic mutants, seedling segregates, and environmental effects or diseases, particularly those caused by viruses. The Fuggle variety has been in existence, and propagated vegetatively, for almost 100 years. According to Percival (8) the original plant was a casual seedling which appeared about 1861 in a flower garden of a George Stace of Horsmonden, Kent, England. Cuttings were introduced to the public by Richard Fuggle of Brenchley, about 1875. The variety was later introduced from England into the United States and now occupies approximately 60% of the
