Abstract

Lolium species characteristically provide high quality forage but lack the stress tolerance of related Festuca species. Procedures for the effective transfer of genes from Festuca into Lolium by introgression will be identified. Alternative stress tolerant species which hybridise and recombine with Lolium will also be used as donors for transfer of stress tolerance traits. Lolium-like derivatives of crossing programmes will be assessed for stress tolerance both in the field and under simulated conditions. The most effective introgressed Festuca traits conferring environmental stress tolerance will be located on Lolium chromosomes using in situ hybridization. Results from physical mapping stress tolerance traits will be integrated with genetic maps under construction. Genes for stress tolerance will be tagged by closely flanking genetic markers for their effective selection in breeding programmes. Anther culture of Festulolium hybrids will be used to reveal gene combinations which optimise complementary traits and to produce homozygous lines. Derivatives from these programmes will be provided for physiological investigations and to be exploited as potential new cultivars. Genes for stress tolerance will be isolated and be made available for transformation into other crop species.
