摘要

It is an object of the invention to screen for hop varieties with low cohumulone ratio and low colupulone ratio, as well as hop varieties with high contents of farnesene and/or linalool within a short time period utilizing a molecular screening method that employs a breeding marker. The invention provides a breeding marker using a polymorphism at the position of the 623rd nucleotide or a polymorphism at the position of the 1820th nucleotide of a polynucleotide consisting of the nucleotide sequence as set forth in SEQ ID NO: 5.
