Abstract

Breeding for drought resistance/tolerance traits that favour continued growth and yield in forage grasses rather than just survival would be of great economic value. Festuca chromosome 3 has proved a rich source of alleles for introgression to enhance the expression of beneficial traits in a Lolium background. Three drought resistant introgression lines and a chromosome 3 recombination series were grown in 1 m deep pipes of compost and drought imposed by withholding water. Root traits were shown to be important in drought resistance and the presence of genes on chromosome 3 with some control over relevant traits has been confirmed. Furthermore it is concluded that Lolium and Festuca should be considered as a single genetic complex of grasses comprising a useful source of variation for breeding.
