There have been no plant breeding developments using species from the tertiary genepool of cultivated barley for breeding or genetics since the VIII<sup>th</sup> International Barley Genetics Symposium in 2000. Hence, the first part of this review describes progress since 2000 in developing and characterising recombinant lines derived from hybridisations between the sole species in the secondary genepool, Hordeum bulbosum L., and cultivated barley, Hordeum vulgare L. The topics discussed in part I are cytogenetics and molecular analysis of recombinant lines. &nbsp;

Abstract Hordeum vulgare and Hordeum bulbosum are two closely related barley species, which share a common H genome. H. vulgare has two nucleolar organizer regions (NORs), while the NOR of H. bulbosum is only one. We sequenced the 2.5 kb 25S-18S region in the rDNA of H. bulbosum and compared it to the same region in H. vulgare as well as to the other Triticeae. The region includes an intergenic spacer (IGS) with a number of subrepeats, a promoter, and an external transcribed spacer (5′ETS). The IGS of H. bulbosum downstream of 25S rRNA contains two 143-bp repeats and six 128-bp repeats. In contrast, the IGS in H. vulgare contains an array of seven 79-bp repeats and a varying number of 135-bp repeats. The 135-bp repeats in H. vulgare and the 128-bp repeats in H. bulbosum show similarity. Compared to H. vulgare, the 5′ETS of H. bulbosum is shorter. Additionally, the 5′ETS regions in H. bulbosum and H. vulgare diverged faster than in other Triticeae genera. Alignment of the Triticeae promoter sequences suggests that in Hordeum, as in diploid Triticum, transcription starts with guanine and not with adenine as it is in many other plants.

Homoeologous Relationships

Hordeum bulbosum chromosomes 1Hb, 4Hb, 6Hb, and 7Hb were identified in five monosomic and one double monosomic H. vulgare – H. bulbosum substitution using 11 isozyme systems. In all substitutions analyzed, diagnostic isozyme bands for H. bulbosum chromosomes were found in the same isozyme systems and zones having diagnostic value for the homoeologous H. vulgare chromosomes. However, bands that are normally diagnostic for the 3Hv region appeared in one 6Hv substitution and in one selfed progeny from another 6Hv substitution.Key words: Hordeum vulgare, Hordeum bulbosum, alien chromosome substitutions, isozymes, chromosome identification, homoeologous relationships.
