PROBLEM TO BE SOLVED: To provide a gene marker existing in the genome DNA of a gramineous plant such as barley and connected to a gene locus controlling small tear caducity, and to provide a method for utilizing the gene marker.;SOLUTION: The detailed chain map of barley was made, and a chain analysis was carried out. Thus, a group of gene markers connected to a gene locus controlling small tear caducity and boarded on barley 3H chromosome were found.;COPYRIGHT: (C)2005,JPO&NCIPI
