Heritability for hop quality include both resins and essential oils was estimated using the intrasire regression of off spring on dam, and relatively high values were obtained, except for alpha‐acids/beta‐acids, β‐caryophyllene and humulene/β‐caryophyllene. A gap was found in the histogram for the cohumulone ratio and the result of x 2 ‐test suggested that a complete dominant gene was involved which produced high ratio. The segregation pattern of farnescene was shown to be skewed and a logarithmic transformation was necessary to calculate heritability as an additive trait. In addition to providing a genetic correlation, these results provide information to the hop breeder which can be used to design more efficient breeding programs.
