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 ...

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.

Epidemiology and control of spot form of net blotch (Pyrenophora teres f. maculata) of barley: a review

Crop & Pasture Science, 2009
Spot form of net blotch (SFNB), caused by the fungus Pyrenophora teres f. maculata, was first described in Denmark in the 1960s and is now a prevalent foliar disease of barley in many countries. This disease should be controlled as a separate disease-causing organism from the net form of net blotch (NFNB), which is caused by P. teres f. teres.

Mapping of barley susceptibility/resistance QTL against spot form net blotch caused by Pyrenophora teres f. maculata using RIL populations

Theoretical and Applied Genetics, 2019
Spot form net blotch (SFNB) caused by the necrotrophic fungal pathogen Pyrenophora teres f. maculata (Ptm) is an important disease of barley worldwide including the major barley production regions of North America. To characterize SFNB resistance/susceptibility quantitative trait loci (QTL), three recombinant inbred line (RIL) populations were ...

Breeding barley for durable resistance to net and spot forms of net blotch

2021
This chapter focuses on breeding barley for durable resistance to net and spot forms of net blotch. It starts by reviewing how Pyrenophora teres f. teres can cause net form net blotch. The chapter then goes on to examine the molecular markers that can be identified to provide resistances to net form net blotch.

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 ...

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.

Pyrenophora teres f. maculata, Causal Agent of Spot Form Net Blotch of Barley, Is an Emerging Pathogen of Durum Wheat.

Phytopathology
Emergent plant pathogens threaten global food security, as they evolve to infect new hosts and spread to new geographic regions. Pyrenophora teres f. maculata is a foliar pathogen of barley that is present worldwide and can cause significant yield losses.

Genetic variation, occurrence of mating types and different forms of Pyrenophora teres causing net blotch of barley in Finland

Mycological Research, 2005
The amplified fragment length polymorphism (AFLP) was used to study genetic variation in Pyrenophora teres causing net blotch of barley in Finland. The mean similarity was 93% between all isolates and a bit higher within two distinct populations based on 175 AFLP markers.
