Abstract

Through creation of a detailed linkage map of barley and QTL analysis thereof, there have been found five genetic markers linked to gene locus involved in barley resistance to yellow mosaic disease and situated on barley 1H chromosome, two genetic markers linked to gene locus involved in barley resistance to yellow mosaic disease and situated on barley 2H chromosome barley resistance to yellow mosaic disease, five genetic markers linked to gene locus involved in barley resistance to yellow mosaic disease and situated on barley 3H chromosome, four genetic markers linked to gene locus involved in barley resistance to yellow mosaic disease and situated on barley 4H chromosome, and two genetic markers linked to gene locus involved in barley resistance to yellow mosaic disease and situated on barley 5H chromosome.

Description

technical field

[0001] The present invention relates to a new genetic marker and its utilization method, in particular to a genetic marker linked to a gene locus related to resistance to barley yellow mosaic disease of barley and its utilization. Background technique

[0002] Barley yellow mosaic disease is caused by barley yellow mosaic virus (hereinafter referred to as "BaYMV") or barley mild mosaic virus (hereinafter referred to as "BaMMV") as the causative virus, and algae A soil-borne viral disease in which Polymyxagraminis of the fungus is a mediator. Once the disease occurs, it will cause necrotic spots or yellowing of leaves, reduction of ramets, stunting, death, etc., and once the disease occurs, even if the soil is not cultivated for 4 to 5 years, it will not be free from disease, so it has become a serious problem. In particular, barley for beer is prone to disease. As the cultivation of barley for beer increases, it occurs not only in Japan but also in China and...
