Genomic constitution of Festuca × Lolium hybrids revealed by the DArTFest array

Complementary attributes of Festuca and Lolium grasses can be combined in hybrid cultivars called Festuloliums, which are becoming increasingly popular fodder crops and amenity plants. Genomic constitution of commercially available Festuloliums was reported to vary from almost equal representation of parental genomes to apparent lack of one of them based on molecular cytogenetic analyses and screening with a small set of DNA markers, both approaches with limited resolution.
