Domestication and intensive selective breeding of plants has triggered erosion of genetic diversity of important stress-related alleles. Researchers highlight the potential of using wild accessions as a gene source for improvement of cereals such as barley, which has major economic and social importance worldwide.

Four newly detected accessions of wild barley (Hordeum vulgare ssp. spontaneum) resistant to powdery mildew caused by Blumeria graminis f. sp. hordei were studied with the aim of finding the number of genes/loci conferring the resistance of individual accessions, the type of inheritance of the genes and their relationships to the Mla locus.

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.

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®, 2021Wheat 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.

Comparative diversity analysis of RFLPs and isozymes within and among populations of Hordeum vulgare ssp. spontaneum. [PDF]
Genetics, 1993 Abstract DNA restriction fragment length polymorphisms (RFLPs) and isozyme variation were surveyed in 268 accessions of a wild barley (Hordeum vulgare ssp. spontaneum) sampled from diverse ecogeographical areas in Israel and Iran. A total of 24 markers was used: 7 well characterized isozyme loci and 15 DNA probes which detected 17 ...

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.

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

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.
