Cytogenetic and molecular genotyping in the allotetraploid Festuca pratensis × Lolium perenne hybrids.

ABSTRACT:

Background

Species of the Festuca and Lolium genera, as well as intergeneric Festuca × Lolium (Festulolium) hybrids, are valuable fodder and turf grasses for agricultural and amenity purposes worldwide. Festulolium hybrids can merge in their genomes agronomically important characteristics. However, in polyploid plants, especially in allopolyploids, the hybridization of divergent genomes could contribute to various abnormalities, such as variability in chromosome number, structural rearrangements, and/or disorders in inheritance patterns. Here we studied these issues in allotetraploid Festuca pratensis × Lolium perenne hybrids.

Results

Cytogenetic procedures, including fluorescent in situ hybridization, genomic in situ hybridization, and molecular markers - inter-simple seque
