Abstract

Lolium and Festuca species, which are the most important source of forage grass in the UK and Western Europe, can be readily hybridised. Crossing procedures for the introduction of important genes from Festuca species into Lolium have been developed. The high frequency of recombination at meiosis between the Lolium and Festuca chromosomes in hybrids and amphiploids suggests that the genomes of the two species are closely related. However, in spite of this chromosome segments in recombinant lines can clearly be distinguished using in situ hybridization techniques. The aim of this research is to 1) facilitate and monitor the introgression of Festuca chromosome segments, carrying agronomically important genes, into Lolium, 2) produce physical genetic maps of Lolium and Festuca and relate these to the developing genetic maps, 3) exploit introgressed Festuca chromosome segments as a means of defining markers tightly linked to agronomically important genes for use in breeding programmes and ultimately gene isolation, 4) develop and refine novel cytogenetic techniques.
