“…Using DHs, resistance genes rym4 (Graner and Bauer 1993), rym5 (Graner et al 1999), the BaYMV/BaYMV-2 resistance of cv. 'Chikurin Ibaraki 1' (Werner et al 2003a), rym13 (Werner et al 2003b) and rym15 (Le Gouis et al 2004) have been mapped and co-segregating markers have been developed for rym11 using DHs in combination with a recombinant interval mapping approach (Nissan-Azzouz et al 2005). The DH populations facilitated a simultaneous test for BaMMV, BaYMV-1 and BaYMV-2 and showed that rym4 is effective against BaMMV and BaY-MV, and that rym5 and rym11 are effective against all three viruses (Graner et al 1999;Pellio et al 2005;Nissan-Azzouz et al 2005), while in 'Chikurin Ibaraki 1' the BaMMV resistance is inherited independently from the BaYMV/BaY-MV-2 resistance (Werner et al 2003a;Le Gouis et al 2004).…”

“…Tuvesson et al 2006). Newly identified genes like rym15 on chromosome 6H (Le Gouis et al 2004) or the BaYMV/BaYMV-2 resistance of 'Chikurin Ibaraki 1' on chromosome 5H (Werner et al 2003) can be incorporated easily in such pyramiding strategies.…”

“…Although, distorted segregation and reduced recombination has been observed in some DH populations used in mapping resistance genes, e.g. in the case of rym15 (Le Gouis et al 2004) and rym11 (NissanAzzouz et al 2005), DH lines combined with dominant marker systems have made a significant contribution to the rapid development of molecular markers for different resistance genes against the barley yellow mosaic virus complex. The resources (identified resistance genes/alleles and associated markers) can be efficiently used in broadening the genetic base of resistance to these viruses and for pyramiding resistance genes.…”

Localisation and combination of resistance genes against soil-borne viruses of barley (BaMMV, BaYMV) using doubled haploids and molecular markers

Barley yellow mosaic virus disease caused by different strains of BaYMV and BaM-MV is a major threat to winter barley cultivation in Europe. Different resistance genes against these viruses have been mapped and suitable PCR-based markers have been developed. In this respect doubled haploid (DH) populations proved to be advantageous as they facilitate a repeated test for resistance against all agents of the barley yellow mosaic virus complex and besides this, dominant marker systems are as informative as co-dominant ones in DHs due to the lack of heterozygous genotypes. Using DH populations resistance genes rym4, rym5, rym11, rym13, rym15 and the BaYMV/BaYMV-2 resistance of the barley cultivar 'Chikurin Ibaraki 1' have been mapped. DHs are also well suited to pyramiding resistance genes against BaMMV and BaYMV. Since homozygous recessive genotypes are more frequent in DHs than in segregating F 2 populations, DHs can be efficiently used to create broadspectrum resistance and to extend the usability of partly overcome resistance genes. Results from employing two different strategies for pyramiding, based on one and two DH-steps, respectively, combining three recessive resistance genes, i.e. rym4/rym5, rym9 and rym11, are presented. The faster strategy based on one haploidy step resulted in the identification of all three and two-way combinations of the respective resistance genes.

“…RAPDs, AFLPs, SSRs and STSs, have been developed for resistance genes rym4, rym5, rym9 and rym11 (Bauer et al, 1997;Graner et al, 1999a;Ordon et al, 1999;Pellio et al, 2000Pellio et al, , 2005Werner et al, 2000) and just recently for the BaYMV/BaYMV-2 resistance of 'Chikurin Ibaraki 1' (Werner et al, 2003a) and the BaMMV resistance of this variety (Le Gouis et al, 2004).

Molecular assessment of genetic diversity in winter barley and its use in breeding

During the last decades extensive progress has been achieved in winter barley breeding with respect to both, yield and resistance to fungal and viral diseases. This progress is mainly due to the efficient use of the genetic diversity present within high yielding adapted cultivars and -with respect to resistance -to the extensive evaluation of genetic resources followed by genetic analyses and introgression of respective genes by sexual recombination. Detailed knowledge on genetic diversity present on the molecular level regarding specific traits as well as on the whole genome level may enhance barley breeding today by facilitating efficient selection of parental lines and marker assisted selection procedures. In the present paper the state of the art with respect to virus diseases, i.e. Barley mild mosaic virus, Barley yellow mosaic virus, and Barley yellow dwarf virus is briefly reviewed and first results on a project aiming on a genome wide estimation of genetic diversity which in combination with data on yield and additional agronomic traits may facilitate the detection of marker trait associations and a more efficient selection of parental genotypes are presented. By field tests of 49 two-rowed and 64 six-rowed winter barley cultivars the genetic gain in yield for the period 1970-2003 was estimated at 54.6 kg ha −1 year −1 (r 2 = 0.567) for the six-rowed cultivars and at 37.5 kg ha −1 year −1 (r 2 = 0.621) for the two-rowed cultivars. Analysis of 30 SSRs revealed a nonhomogenous allele distribution between two and six-rowed cultivars and changes of allele frequencies in relation to the time of release. By PCoA a separation between two and six-rowed cultivars was observed but no clear cut differentiation in relation to the time of release. In the two-rowed cultivars an increase in genetic diversity (DI) from older to newly released cultivars was detected.

“…Genetic analyses resulted in the identification of different recessive resistance genes within the primary gene pool of barley (Götz and Friedt, 1993; Ordon and Friedt, 1993; Konishi et al., 1997). Using molecular techniques, these recessive resistance genes were mapped on chromosomes 1H, 3H, 4H, 5H and 6H and PCR‐based markers were developed that are easy to handle (Graner and Bauer, 1993; Ordon et al., 1995; Bauer et al., 1997; Graner et al., 1995, 1996, 1999a,b; Saeki et al, 1999; Werner et al., 2000, 2003a,b;Le Gouis et al., 2004; Nissan‐Azzous et al., 2005; Pellio et al., 2005; for overview cf.

In cereals, soil‐borne viruses transmitted by the plasmodiophorid Polymyxa graminis (e.g., Barley mild mosaic virus, Barley yellow mosaic virus or Soil‐borne cereal mosaic virus), have increased in importance due to the increase of the acreage infested and because yield losses cannot be prevented by chemical measures. Due to global warming, it is also expected that insect transmitted viruses vectored by aphids (e.g., Barley yellow dwarf virus, Cereal yellow dwarf virus), leafhoppers (Wheat dwarf virus) or mites (e.g., Wheat streak mosaic virus), will become much more important even in cooler regions. The environmentally most sound and also most cost effective approach to prevent high yield losses caused by these viruses is breeding for resistance. Therefore, in contrast to other reviews on cereal viruses, this study briefly reviews present knowledge on cereal‐infecting viruses and emphasizes especially the sources of resistance or tolerance to these viruses and their use in molecular breeding schemes.
