Quantitative trait loci associated with adaptation to Mediterranean dryland conditions in barley
The objective of the present study was to identify quantitative trait loci (QTL) influencing agronomic performance across rain fed Mediterranean environments in a recombinant inbred line (RIL) population derived from the ...
Changes in allele frequencies in landraces, old and modern barley cultivars of marker loci close to QTL for grain yield under high and low input conditions
Changes in alleles frequencies of marker loci linked to yield quantitative trait loci (QTL) were studied in 188 barley entries (landraces, old and modern cultivars) grown in six trials representing low and high yielding ...
Barley adaptation and improvement in the Mediterranean basin
To study barley adaptation and improvement in the Mediterranean basin, a collection of 188 entries comprising landraces and old genotypes and current modern varieties from the Mediterranean basin and elsewhere was tested ...
Evaluation of floral characteristics of barley in the semi‐arid climate of north Syria
Previous studies have revealed that, in areas affected by severe drought, yielding ability and stability of barley (Hordeum vulgare L.) could be improved by increasing the level of heterozygosity. One possible approach to ...
Heritability estimates in contrasting environments as influenced by the adaptation level of barley germ plasm
Low heritability estimates in marginal or stress environments have often been used as one of the main justification for conducting selection work in environments with optimum or near‐optimum conditions for plant growth and ...
Heterosis and mixing effects in barley under drought stress
Yield stability is one of the main breeding objectives in breeding for stress environments, such as the semi-arid areas of Syria. The objectives of this study were to measure the effects of heterogeneity and heterozygosity ...
Plant Genetic Resources and Plant Improvement as Tools to Develop Sustainable Agriculture
This paper addresses the current and future contributions of plant genetic resources and plant improvement to sustainable agriculture with reference to the activities of the International Center for Agricultural Research ...
Differential responses of barley landraces and improved barley cultivars to nitrogen-phosphorus fertilizer
Barley is traditionally grown in the Mediterranean region as a dryland crop, invariably under drought-stressed conditions and often without inputs such as fertilizer. Following research that demonstrated the benefits of ...
Genetic diversity of ICARDA's worldwide barley landrace collection
Twenty genic- and genomic SSR markers were used to study genetic diversity and geographical differentiation of barley from 29 countries through analysis of a worldwide collection of 304 ICARDA's barley landraces. Of these, ...
Genetic diversity and association analysis for salinity tolerance, heading date and plant height of barley germplasm using simple sequence repeat markers
The objective of this study was to investigate the genetic diversity of barley accessions. Additionally, association trait analysis was conducted for grain yield under salinity, heading date and plant height. For this ...
