Method for selection of hop strain, bleeding marker for use in selection of hop strain, and primer set

摘要

It is an object of the invention to screen for hop varieties with high ± acid contents, as well as hop varieties with high contents of ± acids, ² acids, myrcene and/or xanthohumol in addition to ± acids, within a short time period utilizing a molecular screening method that employs a breeding marker. The invention provides a breeding marker represented by the following (a) or (b), which is used for screening of hop varieties with high ± acid contents. (a) A polynucleotide consisting of a nucleotide sequence of 20-1587 continuous nucleotides including nucleotide No.899 of the polynucleotide consisting of the nucleotide sequence as set forth in SEQ ID NO: 5 (wherein the 899th nucleotide is t). (b) A polynucleotide consisting of the sequence complementary to the polynucleotide of (a) above.
