Australian Journal of Agricultural Research, 2007 Late embryogenesis abundant (LEA) proteins are thought to protect against water stress in plants. Characteristics of sequence and expression of barley gene HVA1, a member of LEA group 3 protein, were investigated in hulless barley (Hordeum vulgare ssp. vulgare), associated with phenotypically diverse drought-tolerant genotypes.

Euphytica, 1995
Under drought conditions seminal roots may be more important than nodal roots and plants often reach maturity growing with their seminal roots only. This study was conducted to assess the differences, at an early stage of development, for seminal root characteristics and coleoptile length in three groups of barley germplasm: H.

RAPD characterization of Brazilian barley (Hordeum vulgare ssp. vulgare) varieties
Euphytica, 2000Thirteen varieties of Brazilian barley selected for malting qualities were analysed by RAPD (Random Amplified Polymorphic DNA). Amplification with 18 random primers generated 221 reproducible bands, of which 206 bands were polymorphic (93%):of this number, 137 fragments (62%) detected diversity among varieties and 56 bands (25.34%) allowed the ...

Field Crops Research, 2011
Improving drought tolerance has always been an important objective in many crop improvement programs and is becoming more important as one way of adapting crops to climate changes. However, due to its complexity, the genetic mechanisms underlying the expression of drought tolerance in plants are poorly understood and this trait is difficult to ...

Wild barley (Hordeum vulgare ssp. spontaneum) and landraces are important sources of resistance to biotic and abiotic stresses since they possess wide genetic diversity that may be missing in current elite varieties. In this study, we evaluated a set of 57 barley introgression lines divided in groups depending on the expected levels of introgression ...

Genetic Resources and Crop Evolution, 2006
In the high altitude areas of western Himalaya, barley is a crop of marginal, low input drought stressed environments. The landraces grown in these areas are favoured for their quality, both as grain and straw. However, area under the naked barley landraces, during the last three to four decades, has declined considerably and their ex situ and in situ ...

The deployment of genetic markers is of interest in crop assessment and breeding programmes, due to the potential savings in cost and time afforded. As part of the internationally recognised framework for the awarding of Plant Breeders' Rights (PBR), new barley variety submissions are evaluated using a suite of morphological traits to ensure they are ...

Heredity, 2000
Large numbers of crop plant accessions from all over the world have been amassed in gene banks to secure a gene pool for future breeding programmes. Maintenance of accessions held as seed samples in cold stores involves frequent rejuvenation cycles to ensure the viability of seeds.
