    Notes: Abstract  Several disease-resistant recombinants between barley (Hordeum vulgare) and bulbous barley grass (H. bulbosum) have been obtained in recent years, but the process of characterization is often laborious and time-consuming. In order to improve the identification and chromosomal location of introgressed chromatin from H. bulbosum into the barley genome, we employed sequential genomic in situ hybridization (GISH) and fluorescence in situ hybridization (FISH). GISH enabled us to establish that an introgression was present in the disease-resistant recombinant line, and the subsequent use of FISH, with a short oligonucleotide sequence as probe, allowed us to locate the introgression on the long arm of barley chromosome 2H. These data were confirmed using RFLP probes that hybridize to barley chromosome 2HL.

    Notes: Abstract  We report the genetic mapping of Dwf2, a dominant gibberellic acid (GA3)-insensitive dwarfing gene which has been previously described to cause a very short growth habit in barley (Hordeum vulgare) mutant ‘93/B694’. Using RFLP and microsatellite markers we performed segregation analysis in an F2 population comprising 86 individuals developed from a cross of ‘93/B694’ (Dwf2) with ‘Bonus M2’ (dwf2). Dwf2 was mapped on the short arm of barley chromosome 4H proximal to microsatellite marker XhvOle (5.7 cM) and distal to RFLP marker Xmwg2299 (18.3 cM). The genetic localization of the Dwf2 gene at a homoeologous position to the multiallelic Rht-B1 and Rht-D1 loci in wheat suggests synteny of GA-insensitive dwarfing genes within the Triticeae. Moreover, the extremely prostrate growth habit exhibited in barley ‘93/B694’ (Dwf2) resembles that of wheat plants carrying the genes Rht-B1c (Rht3) or Rht-D1c (Rht10).

    The relationships between the dwarfing genes of wheat and rye (1996)

    Notes: Summary The improvement of lodging resistance by introducing major dwarfing genes, classified either as GA insensitive or GA sensitive, is one of the main strategies chosen by cereal breeders. In the present paper the current knowledge about the genetics, chromosomal localisation and the homoeoallelic relationships of the dwarfing genes in wheat and rye is reviewed. The confusing system of the symbolisation of the GA insensitive dwarfing genes/alleles in wheat is discussed and a nomenclature based on rules for gene symbolisation in wheat is proposed.
