from Steve Tanksley, 7/93 Comparative map based on common cDNA clones Table. Homoeologous relationships of rice, wheat and maize chromosomes deduced from comparative genetic maps. Inferences of chromosomal homoeology based on conserved linkage of several syntenic markers except where indicated by parenthesis which was based on mapping of a single orthologous locus in the different genomes. [ ] indicate pairs of putative homoeologous linkage groups within the maize genome.
