Genetic background analysis of ‘Chamdongjin’. Graphical genotype based on 787 KASP markers (A). The horizontal black lines on the left and right of each chromosome indicate to the physical position and marker, respectively. White and red boxes indicate regions homozygous for ‘Sindongjin’ and ‘HR27195’, respectively. Black star indicates the physical position of Xa21 (Os11g0559200, Chr.11: 20,802,978..20,806,262). Phylogenetic tree of 36 varieties based on 347 KASP markers (B). Red circular dotted line marks the location of ‘Chamdongjin’ (CDJ). The abbreviation of the varieties is as follows. SDJ: ‘Sindongjin’, DM: ‘Dami’, PA: ‘Pyeongan’, BRC: ‘Boramchan’, YHJN: ‘Younghojinmi’, JN: ‘Junam’, UK: ‘Unkwang’, JP: ‘Jopyeong’, SK: ‘Samkwang’, HY: ‘Hwayeong’, HC: ‘Hwacheong’, DA: ‘Dongan’, NP: ‘Nampyeong’, SNR: ‘Saenuri’, HIAM: ‘Hiami’, KSHKR: ‘Koshihikari’, DJ: ‘Dongjin’, OD: ‘Odae’, IP: ‘Ilpum’, GH: ‘Giho’, JU: ‘Joun’, PCS: ‘Pecos’, DWD: ‘Dawdam’, CPRS: ‘Cypress’, HAR2: ‘Hanareum2’.
