Abstract: Provided are a method of producing a beverage having an improved flavor and a method of improving a flavor of a beverage. The method of producing a beverage includes using a raw material containing hops harvested on a day 51 days or more from flowering. The method of improving a flavor of a beverage includes using, in production of a beverage using a raw material containing hops, as the hops, hops harvested on a day 51 days or more from flowering, to thereby improve a flavor of the beverage.

Abstract: The invention provides a detection method for hop latent virus that comprises an extraction step in which hop latent virus RNA is extracted from a specimen, an amplification step in which a primer set containing 4 different oligonucleotides consisting of the nucleotide sequences represented by SEQ ID NO: 1-4 of the Sequence Listing is used for amplification of cDNA by RT-LAMP using the RNA as template, and a judging step in which hop latent virus is judged to be present when amplification of cDNA containing the nucleotide sequence represented by SEQ ID NO: 8 of the Sequence Listing has occurred in the amplification step.

Abstract: The invention provides a detection method for apple mosaic virus that comprises an extraction step in which apple mosaic virus RNA is extracted from a specimen, an amplification step in which a primer set containing 4 different oligonucleotides consisting of the nucleotide sequences represented by SEQ ID NO: 1-4 of the Sequence Listing is used for amplification of cDNA by RT-LAMP using the RNA as template, and a judging step in which apple mosaic virus is judged to be present when amplification of cDNA containing the nucleotide sequence represented by SEQ ID NO: 8 of the Sequence Listing has occurred in the amplification step.

Abstract: DNA, a gene derived from the genome of the hop latent virus, encoding the coat protein of the virus. The DNA is useful of a development of an efficient gene diagnostic method for detecting the hop latent virus-infected plant.

Abstract: DNA, a gene derived from the genome of the hop latent virus, encoding the coat protein of the virus and having the base sequence described in the sequence identification number 1 in the sequence listing. The DNA is useful of a development of an efficient gene diagnostic method for detecting the hop latent virus-infected plant.

Abstract: Disclosed is a method for producing virus-free, rootstocks of hop, which comprises growing a cultured virus-free hop strain in a rooting medium thereby to make it shoot out roots therein followed by culture it in a rootstocks of hop-producing medium having a high saccharide concentration thereby to form rootstocks of hop in the medium. The virus-free, rootstocks of hop are produced under aseptic conditions and are out of the danger of their contamination with viruses, pathogenic vermian or parasites. The plants are highly safe and can be stored well. When planted, these actively shoot out roots and sprouts.

Abstract: A new and distinct variety of Hops, named Hokuto-Ace, is described, which matures rapidly, has excellent bitterness and aroma, and exhibits increased disease resistance, particularly toward downy mildew and gray mold.
