Measuring root traits in barley (Hordeum vulgare ssp. vulgare and ssp. spontaneum) seedlings using gel chambers, soil sacs and X-ray microtomography

Plant and Soil, 2008
Root characteristics of seedlings of five different barley genotypes were analysed in 2D using gel chambers, and in 3D using soil sacs that were destructively harvested and pots of soil that were assessed non-invasively using X-ray microtomography. After 5 days, Chime produced the greatest number of root axes (∼6) and Mehola significantly less (∼4) in ...

Rpg7: A New Gene for Stem Rust Resistance from Hordeum vulgare ssp. spontaneum

Phytopathology®, 2021
Wheat stem rust (causal organism: Puccinia graminis f. sp. tritici) is an important fungal disease that causes significant yield losses in barley. The deployment of resistant cultivars is the most effective means of controlling this disease. Stem rust evaluations of a diverse collection of wild barley (Hordeum vulgare ssp.

Changes in agronomic traits affected by photoperiod and vernalization in a group of wild barley accessions (Hordeum vulgare ssp. spontaneum) and barley cultivars (Hordeum vulgare L.)

Acta Agronomica Hungarica, 2005
The effect of vernalization response and photoperiod sensitivity on reproductive fitness and agronomic traits was examined in a group of 16 H. spontaneum accessions and 8 H. vulgare cultivars in controlled environments. The whole range of plant developmental and agronomic traits was determined by vernalization.

Growth and Development of Six Barley (Hordeum vulgare ssp. vulgare L.) Cultivars in Response to a Model Weed (Sinapis alba L.)

Journal of Agronomy and Crop Science, 2003
AbstractThe aim was to study the growth and development of six spring barley (Hordeum vulgare ssp. vulgare L.) cultivars as a response to a model weed population of Sinapis alba L. The development of light interception profiles over time was characterized for each cultivar in weed‐free stands.

Virus-induced silencing of genes encoding LEA protein in Tibetan hulless barley (Hordeum vulgare ssp. vulgare) and their relationship to drought tolerance

Molecular Breeding, 2011
Expression of the late embryogenesis abundant (LEA) gene is usually associated with plant response to dehydration. In this study, a drought-tolerant genotype was screened from 48 accessions of Tibetan hulless barley (Hordeum vulgare ssp. vulgare). By using virus-induced gene silencing, the influence of two LEA genes (HVA1 and Dhn6) on drought tolerance

Development of candidate introgression lines using an exotic barley accession (Hordeum vulgare ssp. spontaneum) as donor

Theoretical and Applied Genetics, 2004
In the present paper, we report on the selection of two sets of candidate introgression lines (pre-ILs) in spring barley. Two BC2DH populations, S42 and T42, were generated by introgressing an accession of Hordeum vulgare ssp. spontaneum (ISR42-8, from Israel) into two different spring barley cultivars, Scarlett (S) and Thuringia (T).

Leaf scald resistance genes in Hordeum vulgare and Hordeum vulgare ssp. spontaneum : parallels between cultivated and wild barley

Australian Journal of Agricultural Research, 2003
The prerequisite for breeding barley varieties with durable scald resistance is a diversity of genes each with molecular markers for their manipulation in crosses. Here we compare the outcomes of genetic analysis of scald resistance in 5 doubled haploid mapping populations of cultivated barley with 9 third-backcross families that derive from a set of ...

Salinity tolerance of wild barley Hordeum vulgare ssp. spontaneum

Plant Breeding, 2019
AbstractSalinity tolerance of 47 wild barley genotypes and six barley cultivars was evaluated under control and salinity stress (300 mM NaCl) conditions. Shoot and root dry weight (DW), plant height, membrane stability index (MSI), relative water content, survival rate, leaf malondialdehyde (MDA) and proline contents, root and leaf Na, K, Ca and K/Na ...

The Discovery of Resistant Sources of Spring Barley,Hordeum vulgaressp.spontaneum, and Unique Greenbug Biotypes

Journal of Economic Entomology, 2015
The genetic sources for host-plant resistance to the greenbug (Schizaphis graminum Rondani) in barley (Hordeum vulgare ssp. spontaneum) are limited in that only two single dominant genes Rsg1 and Rsg2 are available for the complex of greenbug biotypes.
