“…SNP analysis and associated genetic approaches allow alleles to be efficiently distinguished and associated with traits of interest (Rafalski 2002). Detailed knowledge of the variation in gene sequence and resulting amino acid substitutions in β-amylase genes has been used to explain key differences in β-amylase activity, a major quality trait in barley (Li et al 2002). Similar outcomes can be expected as variation in the sequences of other genes is determined.…”

“…QTLs for a given trait have been detected in multiple mapping populations and environments. For example, several important malting quality QTLs are always detectable in the similar region of chromosome 5H in several experiments (Hayes et al 1993;Han et al 1995;Oziel et al 1996;Tinker et al 1996Li et al 2002, Paris et al 2002. The QTL × environment interaction only results in differences in the magnitude of QTL effects.…”

“…Additionally, Kaneko et al (2000) and Swanston and Molina-Cano (2001) have also demonstrated variation in the thermostability of β-amylase between barley varieties. The β-amylase allele not only determines the level of thermostability but also determines the level of free and bound, with Sd1 exhibiting an higher level of binding than Sd2 (Li et al 2002).…”

“…This enzyme is found in mature grain in 2 forms, free and bound. β-Amylase is a multi-genic locus (Bamy1, Bamy3) (Li et al 2002). While not a true storage protein, β-amylase has been associated with hordeins and other proteins in the endosperm (Broadbent and Palmer 2001).…”

Abstract. The quality of barley for the range of end uses from animal feed to brewing is determined by many genes, making the breeding of new barley varieties difficult. Understanding of the molecular basis of barley quality has been advanced by biochemical studies. More recently, molecular genetic tools are allowing the analysis of the biochemical factors contributing to grain quality. Many genetic loci influencing key quality attributes have been identified by gene mapping. Limited success has been reported in using this information to select for quantitative trait loci for these quality traits in plant breeding. Genomic techniques allowing more detailed analysis of variations in the barley genome in relation to quality promise to extend significantly the value of molecular genetic approaches to barley quality improvement. Definition of the genetic basis of malting quality requires the identification of the genes involved in germination and endosperm modification. Feed quality remains difficult to define. Recent advances are likely to accelerate the rate of discovery, providing new options for analysis of barley quality.
