Adult-plant resistance to leaf scald and net form net blotch in food barley genotypes at a hot spot location in Ethiopia [PDF]

Heliyon
Globally, the fungal pathogens Rhynchosporium graminicola and Pyrenophora teres f. teres produce foliar diseases that significantly reduce barley yield. These diseases are known as leaf scald and net form net blotch, respectively. One hundred food barley

Using a Hybrid Mapping Population to Identify Genomic Regions of Pyrenophora teres Associated With Virulence [PDF]

Frontiers in Plant Science, 2022
Net blotches caused by Pyrenophora teres are important foliar fungal diseases of barley and result in significant yield losses of up to 40%. The two types of net blotch, net-form net blotch and spot-form net blotch, are caused by P. teres f.

Management of Pyrenophora teres f. teres, the Causal Agent of Net Form Net Blotch of Barley, in A Two-Year Field Experiment in Central Italy [PDF]

Pathogens, 2022
Pyrenophora teres is the causal agent of barley net blotch (NB), a disease that can be found in two different forms: net form (NFNB), caused by P. teres f. teres, and spot form (SFNB), caused by P. teres f. maculata.

Barley Sources of Resistance to the Net Form of Net Blotch (Pyrenophora teres f. teres)

Biology and Life Sciences Forum, 2023
Barley is one of the economically important crop species and the net form of net blotch (NFNB) caused by Pyrenophora teres f. teres has a significant impact on the quantity and quality of grain yield.

Demethylase Inhibitor Fungicide Resistance in Pyrenophora teres f. sp. teres Associated with Target Site Modification and Inducible Overexpression of Cyp51 [PDF]

Frontiers in Microbiology, 2016
Pyrenophora teres f. sp. teres is the cause of net form of net blotch, an economically important foliar disease in barley (Hordeum vulgare). Net and spot forms of net blotch are widely controlled using site-specific systemic fungicides.

Adult-plant resistance and a suitable method of reaction determination to scald and net form net blotch in malt barley genotypes at a hot spot location in Ethiopia

Discover Agriculture
Scald and net form net blotch caused by fungal pathogens Rhynchosporium secalis and Pyrenophora teres f. teres, respectively, are significant foliar diseases affecting barley production on a global scale, and they lead to substantial reductions in both ...

Genome-wide association mapping of net form net blotch resistance in barley at seedling and adult plant stages

Frontiers in Agronomy
Net form net blotch (NFNB) caused by Pyrenophora teres f. sp. teres (Ptt) is an emerging barley disease in several countries. It causes severe yield and quality losses due to infection of leaves, kernels, and stems.

Mapping of quantitative trait loci associated with resistance to net form net blotch (Pyrenophora teres f. teres) in a doubled haploid Norwegian barley population. [PDF]

PLoS ONE, 2017
Barley net blotch caused by the necrotrophic fungus Pyrenophora teres is a major barley disease in Norway. It can cause grain shriveling and yield losses, and resistance in currently grown cultivars is insufficient.

Fine Mapping of the Barley Chromosome 6H Net Form Net Blotch Susceptibility Locus

G3: Genes, Genomes, Genetics, 2016
Net form net blotch, caused by the necrotrophic fungal pathogen Pyrenophora teres f. teres, is a destructive foliar disease of barley with the potential to cause significant yield loss in major production regions throughout the world.

Virulence Spectra of Hungarian Pyrenophora teres f. teres Isolates Collected from Experimental Fields Show Continuous Variation without Specific Isolate × Barley Differential Interactions [PDF]

Journal of Fungi
Pyrenophora teres f. teres (Ptt), the causal agent of net form net blotch (NFNB) disease, is an important and widespread pathogen of barley. This study aimed to quantify and characterize the virulence of Ptt isolates collected from experimental fields of
