Genetic studies on net blotch resistance in a barley cross
Canadian Journal of Plant Science, 1996An investigation was initiated to study the genetics of resistance to three isolates of Pyrenophora teres (WRS102, WRS858, and WRS857), which have been routinely used for screening for net blotch resistance in Canada. The F1, F2, and doubled-haploid lines were derived from a Leger/CI9831 cross of barley (Hordeum vulgare L.).

Observations on the Development of Leaf Blotch and Net Blotch of Barley from Barley Debris, 1968
Plant Pathology, 1969SUMMARY A survey of 56 fields of spring barley in West Sussex in 1968 showed that the extent and severity of leaf blotch ( Rhynchosporium secalis ) and net blotch ( Pyrenophora teres ) in the crop depended on the amount of stubble ...

Diversity among Finnish net blotch isolates and resistance in barley
Euphytica, 1996Seedlings of a differential barley (Hordeum vulgare L.) series (21 genotypes) and of six check genotypes were used in the greenhouse to assess variation in virulence among 20 single-spore isolates of the net blotch pathogen, Pyrenophora teres Drechs. f. teres Smedeg., collected from various sites in Finland.

Breeding barley for durable resistance to net and spot forms of net blotch
2021This 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.

Responses of Wild and Cultivated Barley from West Asia to Net Blotch and Spot Blotch
Crop Science, 1995Wild species and cultivated landraces from the center of crop origin may provide new sources of resistance to a variety of plant diseases that plague genetically uniform crops around the world. This study was conducted to assess resistance to Canadian isolates of three foliar pathogens [Cochliobolus sativus (Ito & Kurib.) Drechsl.

Theoretical and Applied Genetics, 2017
A diverse collection of barley lines was phenotyped with three North American Pyrenophora teres f. teres isolates and association analyses detected 78 significant marker-trait associations at 16 genomic loci. Pyrenophora teres f. teres is a necrotrophic fungal pathogen and the causal agent of the economically important foliar disease net form net ...

Identification and mapping of net form of net blotch resistance in South African barley
Molecular Breeding, 2018Net 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.

An Improved Technique for Determining Net Blotch Resistance in Barley
Plant Disease, 1991An agar leaf disk technique is described for determining net blotch resistance in barley. Leaves of barley were collected and disinfested with different methods using alcohol and sodium hypochlorite. Twelve disinfested leaf disks were placed on 1.5% water agar in petri dishes with 0, 80, or 120 μg/ml of benzimidazole.

Inheritance of Resistance to Net Blotch in Barley in Morocco
Plant Disease, 1996Barley cultivars currently grown in Morocco do not have satisfactory resistance to net blotch, caused by Pyrenophora teres. This study determined the inheritance of resistance in spring barley to net blotch in 11 F 2:5 populations in the field in Morocco.
