Responses of Wild and Cultivated Barley from West Asia to Net Blotch and Spot Blotch

Crop Science, 1995
Wild 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.

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.

Inheritance of Partial Resistance to Net Blotch in Barley

Plant Breeding, 1990
AbstractReciprocal crosses were made between 9 different barley genotypes with high genetic variability for net blotch resistance. Parents and 72 F1 plants were used to determine the inheritance of partial resistance to net blotch. Four experiments, one in a growth chamber on seedlings and 3 others in the field on adult plants, were undertaken using a ...

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 ...

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

Peanut net blotch caused by Didymosphaeria arachidicola (chochrjakov) comb.nov.

Transactions of the British Mycological Society, 1976
This disease was 1st recorded in Qd on groundnut in 1964 and has since occurred intermittently. In experimental plots Valencia and Spanish type cvs. were more severely affected than Virginia types. Initially lesions are quite small, consisting of a few linear anastomosing necroses in an irregular pattern.

Understanding plant–pathogen interactions in net blotch infection of cereals

2021
An economically important disease of barley that causes significant yield and quality losses is net blotch caused by the necrotrophic fungal pathogen Pyrenophora teres. To reduce the impact of net blotch the research community is engaging in basic and applied research to enhance genetic resistances, as it is the most economic and sustainable management

Association mapping utilizing diverse barley lines reveals net form net blotch seedling resistance/susceptibility loci

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, 2018
Net 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.

Genetic studies on net blotch resistance in a barley cross

Canadian Journal of Plant Science, 1996
An 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.).
