Net blotch in semi-arid regions of Morocco II

Field Crops Research, 2002
Abstract Net blotch incited by Pyrenophora teres f. teres is an important constraint for barley production in the semi-arid regions of Morocco, reaching epidemic proportions under favorable weather conditions. In this study, we generated 480 epidemics. These epidemics were characterized at five sites and for six different varieties with plants either

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

Achieving durable disease resistance in cereals, 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.

Advances in understanding the epidemiology, molecular biology and control of net blotch and the net blotch barley interaction

2021
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.

Sensitivity of Resistance to Net Blotch in Barley

Journal of Phytopathology, 1999
The 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.

Spring barley accessions with dual spot blotch and net blotch resistance

Canadian Journal of Plant Pathology, 2008
Spot blotch and net blotch are common foliar diseases of barley in the upper midwestern United States and are capable of causing significant reductions in both the yield and quality of the crop. Currently, there are no cultivars grown in the region that possess high levels of resistance to net blotch, and recent evidence suggests that the durable spot ...

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 ...

Resistance of barley accessions from the East Asian Center of crop diversity to the net and spot forms of the net blotch pathogen

PROCEEDINGS ON APPLIED BOTANY GENETICS AND BREEDING
Background. Barley is a major fodder crop and valuable raw material for the brewing industry. A harmful disease of barley is net blotch, caused by the hemibiotrophic fungus Pyrenophora teres Drechsler, which exists in two forms that differ in symptoms

Effects of meteorological data on the development of net blotch of spring barley in Turkey

International Service Availability Symposium
Ensuring sustainability and productivity in plant production is of paramount importance, and plant diseases represent a significant challenge in this regard. Meteorological changes due to climate change cause the dynamics of plant pathogens to change and
