“…The majority of QTLs analyses for yield and yield component traits in barley were conducted with early balanced populations (Hayes et al 1993, Thomas et al 1995Tinker et al 1996;Bezant et al 1997, Yin et al 1999, Marquez-Cedillo 2000, while only four QTLs analyses have so far been conducted in advanced backcross barley populations (Matus et al 2003;Pillen et al 2003, Li et al 2004. Some QTLs in classical QTL studies consistently mapped to the same genomic regions despite a wide range of different germplasms used.…”

The objective of the present study was to identify favourable exotic Quantitative Trait Locus (QTL) alleles for the improvement of agronomic traits in the BC 2 DH population S42 derived from a cross between the spring barley cultivar Scarlett and the wild barley accession ISR42-8 (Hordeum vulgare ssp. spontaneum). QTLs were detected as a marker main effect and/or a marker · environment interaction effect (M · E) in a three-factorial ANOVA. Using field data of up to eight environments and genotype data of 98 SSR loci, we detected 86 QTLs for nine agronomic traits. At 60 QTLs the marker main effect, at five QTLs the M · E interaction effect, and at 21 QTLs both the effects were significant. The majority of the M · E interaction effects were due to changes in magnitude and are, therefore, still valuable for marker assisted selection across environments. The exotic alleles improved performance in 31 (36.0%) of 86 QTLs detected for agronomic traits. The exotic alleles had favourable effects on all analysed quantitative traits. These favourable exotic alleles were detected, in particular on the short arm of chromosome 2H and the long arm of chromosome 4H. The exotic allele on 4HL, for example, improved yield by 7.1%. Furthermore, the presence of the exotic allele on 2HS increased the yield component traits ears per m 2 and thousand grain weight by 16.4% and 3.2%, respectively. The present study, hence, demonstrated that wild barley does harbour valuable alleles, which can enrich the genetic basis of cultivated barley and improve quantitative agronomic traits.

“…The present study demonstrated that there was small difference of the closest linked markers for different traits in the traditional QTL region for malting quality Li et al 2003Li et al , 2005Mather et al 1997;Marquez-cedillo et al 2000;Panozzo et al 2007;Von Korff et al 2008) when more molecular markers were mapped in the chromosome region. The results in Table 3 indicate that there exist multi-locus clusters for different quality traits in this chromosome region.…”

“…Significantly, the markers provide a basis for characterizing barley germplasm and identifying different haplotypes using association mapping approach. Previous studies showed that there were multiple alleles for this chromosome region with various quality profiles (Marquez-Cedillo et al 2000;Li et al 2003). Thus, the marker combinations could also be used to select multiple alleles in complex crosses in breeding programs to understand the relationship between the polymorphism and malting quality.…”

“…Numerous genes and QTL have been identified that are related to malting quality and these have been reviewed by various authors (Kleinhofs and Han 2002;Fox et al 2003;Li et al 2009). Although there was strong QTL × E interaction for the malting quality traits (Panozzo et al 2007), the terminal region of chromosome 5HL has been consistently detected to control multiple malting quality traits (Mather et al 1997;Marquez-Cedillo et al 2000;Collins et al 2003;Li et al 2003;Hayes et al 2003;Li et al 2005;Panozzo et al 2007;Von Korff et al 2008). These traits included malt extract, diastatic power, free amino acid nitrogen, soluble nitrogen, alpha-amylase activity, wort viscosity, beta-glucan and beta-glucanase.…”

“…Fertility of lateral spikelet is considerably enhanced by I in combination with Vrs1vrs1 heterozygotes (Lundqvist and Lundqvist 1987). The I gene was located on the short arm of chromosome 4H (Marquez-Cedillo et al 2000, Hori et al 2005. Alleles at the intermedium spike-c (int-c) also alter the size of lateral spikelets (Lundqvist and Lundqvist 1987) and all mutant lines for int-c were artificially induced in two-rowed barley (Lundqvist et al 1997).…”

The lateral spikelets of two-rowed barley are reduced in size and sterile, but in six-rowed barley all three spikelets are fully fertile. The trait is largely controlled by alleles at the vrs1 locus on chromosome arm 2HL, as modified by the allele present at the I locus on chromosome arm 4HS. Molecular markers were developed to saturate the 4HS region by exploiting expressed sequence-tags, either previously mapped in barley to this region, or present in the syntenic region of rice chromosome 3. Collinearity between rice and barley was strong in the 4.8 cM interval BJ468164-AV933435 and the 10 cM interval AV942364-BJ455560. A major QTL for lateral spikelet fertility (the I locus) explained 44% of phenotypic variance, and was located in the interval CB873567-BJ473916. The genotyping of near-isogenic lines for I placed the locus in a region between CB873567 and EBmac635, and therefore the most likely position of the I locus was proximal to CB873567 in a 5.3 cM interval between CB873567-BJ473916.
