Popis:	GISH has been a particularly useful technique for studying the Lolium-Festuca species complex of forage grasses. The reason for this utility is two-fold: (i) the complex is unique amongst crop plants in which fertile hybrids, and backcross progenies, can be produced which recombine genomes and promiscuously exchange their genes through homoeologous recombination; (ii) dispersed repetitive DNAs differ between species, and this allows tracking of the identity of chromosomes and chromosome segments. This tracking property has enabled several fruitful lines of research to produce a harvest of new information for both fundamental and practical purposes. We review this first decade of GISH (genomic in situ hybridization) in Lolium-Festuca, and discuss and summarize the achievements which have accrued.
