Sensitivity of Resistance to Net Blotch in Barley
Journal of Phytopathology, 1999The aim of this study was to demonstrate various methods of analysing terminal net blotch, Pyrenophora teres Drechs. f. teres Smedeg., severity data from 15 spring barleys, Hordeum vulgare L., grown in Finnish official variety trials in five environments.

Net blotches are the most widely distributed foliar diseases of barley worldwide, causing significant losses in grain yield. They occur as net form net blotch, caused by Pyrenophora teres f. teres and spot form net blotch caused by P. teres f. maculata. Both sexual and asexual reproduction play a role in the P.

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.

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 ...

Effects of small air ions on net blotch disease of barley
International Journal of Biometeorology, 1977Small positive air ions significantly reduced the number of lesions and percentage of leaf area covered by lesions of net blotch disease of barley. Appearance of disease symptoms was delayed by three days when plants were exposed to an atmosphere of positive ions. No such effect was observed for negative air ions.

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.

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.

Plant Pathology, 1983
The effect of barley yellow dwarf virus (BYDV) on the development of net blotch (Pyrenophora eves) and leaf blotch (Rhynchosporium secalis) was examined on seven barley cuitivars. Seedlings were infected with BYDV at the two‐leaf stage (G.S. 12). Their susceptibility to three isolates of p teres and isolates of two races (U.K. 1, U.K. 2) of R.

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.
