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.

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.

Genetic analysis of net form net blotch resistance in barley lines CIho 5791 and Tifang against a global collection of P. teres f. teres isolates [PDF]
Theoretical and Applied Genetics, 2016 A CIho 5791 × Tifang recombinant inbred mapping population was developed and used to identify major dominant resistance genes on barley chromosomes 6H and 3H in CI5791 and on 3H in Tifang. The barley line CIho 5791 confers high levels of resistance to Pyrenophora teres f.

Exploiting barley landraces to reintroduce lost genetic diversity: Resistance to net form net blotch
Crop scienceCenturies of barley (Hordeum vulgare) domestication and selection has resulted in reduced genetic diversity in modern cultivars, limiting breeder's options to select desirable traits.

Spot form of net blotch (SFNB), caused by Pyrenophora teres f. maculata caused up to 25 % (0.9 t/ha) grain yield loss to barley and significant reductions in grain quality parameters such as retention (13 %), screenings (5 %) and grain weight (6 %) in the Wimmera region of Victoria during 2005–11.

Spot form of net blotch (SFNB) (Pyrenophora teres f maculata) is an economically damaging foliar disease of barley in many of the world’s cereal growing areas. The development of SFNB-resistant cultivars may be accelerated through the use of molecular markers. A screen for SFNB resistance in 96 lines identified four new sources of resistance, including

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 ...

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.

AbstractTo develop molecular markers against Pyrenophora teres f. teres in barley, a detached leaf assay was conducted on two DH populations with a set of 11 single conidial lines (SCLs). Out of these, three showed different reactions in the DH population ‘Uschi × HHOR3073’ and two in ‘(P x V) × HHOR9484’.
