Concerns regarding the most effective means of evaluating
segregating generations of spring barley prompted this investigation. Three methods of selection were considered: bulk, pedigree, and single seed descent. F₆ lines derived by each method
were grown in a replicated yield trial. The effectiveness of each
method was measured in terms...
Vernalization - the requirement of a period of low temperature to induce the transition from a vegetative to a reproductive state - is an evolutionarily and economically important trait in the Triticeae. The genetic basis of vernalization in barley (Hordeum vulgare subsp. vulgare), a model crop for the Triticeae, was...
Making quality and winterhardiness in barley are "ultimate" phenotypes composed of
component, quantitatively inherited traits. A 69-point genome map of the seven chromosomes of
barley was used, in conjunction with multi-environment phenotypes for grain yield and malting
quality, to determine the chromosome locations of quantitative trait loci (QTLs). A combined...
Higher grain yield is a key objective in barley (Hordeum vulgare. L) breeding.
Despite extensive research on the genetics of yield and its components, selection for
yield per se is still the most extensively employed because of negative relationships
among components, modest correlations between yield and any particular component,
and...
Wild barley (Hordeum vulgare subsp. spontaneum) could be a source of useful genes for improving cultivated barley. The useful genes present in Hordeum vulgare subsp. spontaneum may be new alleles at described loci, or these may be entirely new genes in the sense that there is limited allelic variation at...
Characterization of the determinants of economically important phenotypes
showing complex inheritance should lead to more effective use of genetic
resources. This study was conducted to determine the number, genome location and
effects of QTLs determining malting quality and agronomic traits in the two North
American barley quality standards. Using a...
