Interspecific hybridisation of forage grasses has been undertaken at the Institute of Agriculture since the end of the 1970’s. Lolium perenne (Lp) and Festuca pratensis (Fp) aneuploid hybrids and a tetraploid Fp cultivar ‘Patra’ have been utilised for crossing. Two cultivars – ‘Saikava’ and ‘Vizule’, which contain Lp, L.multiflorum (Lm) and Fp germplasm have been registered. These xFestulolium cultivars were assessed in field conditions, and the genetic composition was determined by morphological parameters as well as by utilisation of species-specific molecular markers. In total, a higher proportion of Lolium (0/L) genotypes were identified in the analysed loci (62%), compared to hybrid genotypes (F/L – 34%). Festuca genotypes (F/0) were found in 3% of all loci. A higher proportion of Lolium alleles were found within all the xFestulolium cultivars: Ape – 74.9%, Lorry – 81.8%, Vizule – 72.9%, Saikava – 75.8%, Lofa – 74.3%, Punia – 58.9%. |
