✦ Synopsis

Mitochondrial (mt) DNA of a new type of rye cytoplasm ('Gülzow', G) that induces cytoplasmic male sterility (CMS) was analyzed and compared with rye mtDNAs of different origins MtDNA of the G type was easily distinguishable from mtDNA of another CMS source, 'Pampa' (P) type, and from mtDNA of fertile lines with respect to restriction fragment patterns and hybridization with mitochondrial genes. The results of the molecular analyses indicate a close, but not identical relationship between the mtDNA of the G type cytoplasm and that of cv 'Pluto'.
