The cytoplasmic variation in the genus Avena has been studied so far by two means, i.e. electrophoretic characterisation of the large subunit of ribulose 1,5-bisphosphate carboxylase (Rubisco)(1), and a comparative study of alloplasmic lines of common oats(2). Since 1976, the restriction endonuclease analysis of organellar DNAs has become a new tool for studying genetic diversity among cytoplasms of different plant species. Due to the maternal transmission of organellar DNAs, this approach is useful to determine the cytoplasm donor to polyploid species(3). We investigated the variability of chloroplast(ct) and mitochondrial(mt) DNAs among Avena species to clarify their maternal lineage.
