Linkage maps of rice newly constructed gathering latest information are
presented, since the maps were not presented in RGN 2 and 3. The new maps
include all the information reported in papers listed in Literature on Genic
Analysis, which is presented at the end of this Committee Report. However,
the old numbering systems for the linkage groups, chromosomes and trisomics
are used as the adoption of a unified numbering system of chromosomes is not
agreed yet.
