Identification of Aegilops ovata chromosomes added to the wheat (Triticum aestivum L.) genome
1999
Landjeva,S. | Ganeva,G.
A partial amphiploid Triticum aestivum cv.'Chinese Spring'x Aegilops ovata was backcrossed to 'Chinese Spring'to produce wheat-Ae.ovata addition lines.Using the chromosome N-banding technique five different Ae.ovata chromosomes were identified as additions to the wheat genome in the backcross-derivates.Plants with 2n=43 carried either single alien chromosome as monosomic addition, or more than one alien chromosomes as addition-substitution.The 44-chromosome plants were identified as disomic additions, double monosomic additions, or addition-substitutions.Some of the alien chromosomes had modified heterochromatin structure in comparison with the corresponding chromosomes of the Aegoilops ovata parent.
