[Inheritance of organelle DNA in rye (Secale cereale L.) and wheat (x Triticale Thch.) hybrids].
The mode of inheritance of chloroplast and mitochondrial DNA (mtDNA) in rye x triticale intergeneric hybrids has been studied with the use of specific PCR markers for loci 18S/5S and 3'rbcL in organelle DNA. In rye x triticale BC1, mtDNA copies of two types, paternal and maternal, have been found; in BC2 plants, only paternal mtDNA and chloroplast DNA (cpDNA) have been detected. Mechanisms determining the inheritance and/or differential amplification of organelles of a specific type are discussed.
