Abstract
A new and distinct hop plant is described. The triploid cultivar results out of selection from a population of seedlings derived from the deliberate crossing the unreleased selections 00-L125-09 (not patented) and 99-58-39 (not patented). The new variety, ‘Hort3953’, is distinguished from others by its late spring growth and late cone maturity along with a high alpha:beta acids ratio. The new variety is suitable for beer flavouring.
