Validation of a new spot form of net blotch differential set and evidence for hybridisation between the spot and net forms of net blotch in Australia

Australasian Plant Pathology, 2014
A recently developed spot form of blotch differential set of 16 barley lines was tested for reaction response to 60 Pyrenophora teres f. maculata isolates from geographically disperse barley crops of Australia. Twelve barley lines (Arimont, Barque, Chebec, CI5286, CI5791, CI9214, CII6150, Dairokkaku, Esperance Orge 289, Galleon, Keel, Skiff, Torrens ...

Identification and mapping of net form of net blotch resistance in South African barley

Molecular Breeding, 2018
Net form of net blotch (NFNB) caused by the fungus Pyrenophora teres f. teres is an economically important foliar disease of barley (Hordeum vulgare) in southern and eastern Africa. Little attention has been given to disease resistance breeding, and knowledge about the presence of NFNB resistance in breeding lines is limited.

Occurrence and frequency of spot form and net form of net blotch disease of barley in Algeria

Journal of Plant Diseases and Protection, 2019
In Algeria, barley (Hordeum vulgare L.) is the second most cultivated cereal after wheat; however, this crop is challenged by several foliar diseases. Net blotch is one of the most common diseases of barley in Algeria and is caused by the fungus Pyrenophora teres (Died.) Drechsler, which occurs in two forms: P. teres f.

Mapping of adult plant resistance to net form of net blotch in three Australian barley populations

Australian Journal of Agricultural Research, 2007
Net form of net blotch (NFNB), caused by Pyrenophora teres Drechs. f. teres Smedeg., is a serious disease problem for the barley industry in Australia and other parts of the world. Three doubled haploid barley populations, Alexis/Sloop, WI2875-1/Alexis, and Arapiles/Franklin, were used to identify genes conferring adult plant resistance to NFNB in ...

Major Susceptibility Gene Epistasis over Minor Gene Resistance to Spot Form Net Blotch in a Commercial Barley Cultivar

Phytopathology®, 2023
Spot form net blotch, caused by Pyrenophora teres f. maculata, is a significant global disease of barley ( Hordeum vulgare). Baudin, a barley cultivar that was until recently extensively grown in Western Australia, was reported as having minor seedling resistance.

Genome‐Wide Association Mapping of Seedling Net Form Net Blotch Resistance in an Ethiopian and Eritrean Barley Collection

Crop Science, 2019
ABSTRACTThe net form of net blotch, caused by Pyrenophora teres f. teres (Ptt), is an economically important disease of barley (Hordeum vulgare L.) that is best managed by breeding for resistance. Previous linkage mapping and genome‐wide association studies (GWAS) have identified many resistance quantitative trait loci (QTL) in barley.

Efficacy of spot form of net blotch suppression in barley from seed, fertiliser and foliar applied fungicides

Crop Protection, 2022
Abstract Spot form of net blotch (SFNB), caused by Pyrenophora teres f. maculata is a prevalent and damaging foliar disease of barley (Hordeum vulgare). Fungicides are commonly used to manage SFNB infection and reduce production loss in susceptible varieties.

Identification of quantitative trait loci for net form net blotch resistance in contemporary barley breeding germplasm from the USA using genome-wide association mapping

Theoretical and Applied Genetics, 2020
Association mapping study conducted in a population of 3490 elite barley breeding lines from ten barley breeding programs of the USA identified 12 QTLs for resistance/susceptibility to net form of net blotch. Breeding resistant varieties is the best management strategy for net form of net blotch (NFNB) in barley (Hordeum vulgare L.) caused by ...

Genetic analysis of a worldwide barley collection for resistance to net form of net blotch disease (Pyrenophora teres f. teres)

Theoretical and Applied Genetics, 2019
A total of 449 barley accessions were phenotyped for Pyrenophora teres f. teres resistance at three locations and in greenhouse trials. Genome-wide association studies identified 254 marker-trait associations corresponding to 15 QTLs. Net form of net blotch is one of the most important diseases of barley and is present in all barley growing regions ...

Proteomic analysis reveals the potential involvement of xylanase from Pyrenophora teres f. teres in net form net blotch disease of barley

Australasian Plant Pathology, 2014
The barley pathogen Pyrenophora teres f. teres (Ptt) produces proteinaceous toxins that contribute to the necrotic symptoms observed during net form net blotch (NFNB) disease. To better understand the relationship between these toxins and virulence, a proteomics approach was used to identify proteins differentially expressed in a more virulent Ptt ...
