Abstract
Genetic distance was calculated based on random amplified polymorphic DNA (RAPD) analysis among hop varieties. Multiple regression analysis of the amount of the major chemical components in selected hop varieties on their genetic distance from major hop varieties was performed. Regression functions with relatively high multiple correlations were obtained although no prediction could be obtained for farnesene. The regression function was applied to male parent evaluation. THe results of this study suggest that the use of genetic distance for predicting phenotypic values of major chemical components of hop varietiesis suitable. The method presented here should enable to select individuals with stable qualities before cones are produced and male parents for which phenotypic data could not be obtained.
