The relationships between known three linkage groups, the sixth, the ninth, and the twelfth, and chromosomes in rice (Oryza sativa L.)were reexamined by using isogenic lines of Taichung 65 with marker genes and translocation stocks. The marker genes, ghl (gold hull) and d1 (daikoku-type dwarf) included in the sixth linkage group, nl1 (neck leaf) in the ninth, and gl1 (glabrous) in the twelfth group were all found to be located on the second chromosome. Linkabae order of these marker genes and seven interchange breakpoints on this chromosome was established as gh1-d1-2-3-2-3c-nl1-2-6a-2-7a-2-3b-2-lOa-2-3d-gl1 Consequently, two more linkabae groups remain to be established.
