Abstract
The advantages of androgenesis from Lolium × Festuca hybrids as a means towards enhanced gene expression and capture of rare genetic variation are reviewed. New evidence is presented for the technique’s use in combination with introgression-mapping for targeting Festuca-derived genes for enhanced freezing-tolerance. As a starting point, a dihaploid genotype derived by androgenesis from a Lolium multiflorum × Festuca pratensis amphiploid (2n = 4x = 28) hybrid cultivar is used as female parent in a backcross breeding programme with L. multiflorum (2n = 2x = 14). A derivative of the backcross␣breeding programme was a genotype of L.␣multiflorum (2n = 2x = 14) incorporating a F.␣pratensis introgression on chromosome 4 that was more freezing-tolerant than Lolium.
