Abstract
1) Karyomorphological studies on the Aegilops and Triticum were carried out in this paper.
2) Karyotypes of these species were analysed as follows comparing with the genomes as AA, BB, and DD;
3) Relationship between karyotype and genome of Triticum was discussed. The karyotype of the DD genome was established as coinciding completely with that of Aegilops squassosa which has been conceived as a diploid species having the DD genome.
4) Among these genomes, one these genome has a constant karyotype even in different species. On the contrary, any different karyotype was not observed in one genome of Triticum though it was found in Secale and Hordeum as the present author reported previously. This relationship was called by the present author as “Parallelism of genome and karyotype”
5) Karyomorphology of the hybrids from the intergeneric hybridization among Aegilops, Secale, and Triticum is easy to analyse with the results obtained in this paper and those of obtained previously by the present author.
