Summary

Southern blot hybridization of total DNA to defined mitochondrial DNA sequences provides a sensitive assay for mtDNA variation in the genera of Triticum and Aegilops. A clear distinction between cytoplasms of tetraploid species sharing the “AG” haploid genome is reported for the first time. The Sitopsis section of the genus Aegilops showed the most extensive intra- and inter-specific variation, whereas no variation could be detected among the cytoplasms of polyploid Triticum species (wheats) sharing the AB haploid genome. Extensive cytoplasmic intraspecific diversity was revealed in Ae. speltoides.
