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.

Genome-wide association studies of net form of net blotch resistance at seedling and adult plant stages in spring barley collection

Molecular Breeding, 2018
Net form of net blotch (NFNB) of barley (Hordeum vulgare L.), caused by Pyrenophora teres f. teres (Ptt) Drechsler (anamorph: Drechslera teres [Sacc.] Shoem.), is considered one of the major constraints of successful barley production in major barley growing regions of the world. Resistance to NFNB was evaluated in a barley collection of 336 genotypes (

Association mapping of seedling resistance to spot form net blotch in a worldwide collection of barley. [PDF]

Phytopathology®, 2015
Spot form net blotch (SFNB), caused by the necrotrophic fungal pathogen Pyrenophora teres f. maculata, is an important foliar disease of barley in major production regions around the world. Deployment of adequate host resistance is challenging because the virulence of P. teres f.

Four Reference Quality Genome Assemblies of Pyrenophora teres f. maculata: A Resource for Studying the Barley Spot Form Net Blotch Interaction

Molecular Plant-Microbe Interactions, 2021
Pyrenophora teres is the causal agent of net blotch, the most devastating foliar disease of barley. In nature, net blotch is seen in two forms, net form net blotch, caused by P. teres f. teres, and spot form net blotch, caused by P. teres f. maculata. To

Demethylase Inhibitor Fungicide Resistance in Pyrenophora teres f. sp. teres Associated with Target Site Modification and Inducible Overexpression of Cyp51 [PDF]

Frontiers in Microbiology, 2016
Pyrenophora teres f. sp. teres is the cause of net form of net blotch, an economically important foliar disease in barley (Hordeum vulgare). Net and spot forms of net blotch are widely controlled using site-specific systemic fungicides.

Mapping Net Form Net Blotch and Septoria Speckled Leaf Blotch Resistance Loci in Barley [PDF]

Phytopathology®, 2010
Septoria speckled leaf blotch (SSLB), caused by Septoria passerinii Sacc., and net form net blotch (NB), caused by Pyrenophora teres f. teres Drechsler, are fungal diseases that decrease the yields of barley in the Upper Midwest. An effective way to manage these diseases is to plant resistant cultivars.

Control of net form of net blotch in barley from seed- and foliar-applied fungicides [PDF]

Crop & Pasture Science, 2019
Net form of net blotch (NFNB), caused by Pyrenophora teres f. teres, is a major foliar disease of barley (Hordeum vulgare L.) worldwide that can cause grain yield and quality loss in susceptible varieties.

Exploiting barley landraces to reintroduce lost genetic diversity: Resistance to net form net blotch

Crop Science
Centuries of barley (Hordeum vulgare) domestication and selection has resulted in reduced genetic diversity in modern cultivars, limiting breeder's options to select desirable traits.

Major Susceptibility Gene Epistasis over Minor Gene Resistance to Spot Form Net Blotch in a Commercial Barley Cultivar.

Phytopathology®, 2023
Spot form net blotch, caused by Pyrenophora teres f. maculata, is a significant global disease of barley (Hordeum vulgare). Baudin, a barley cultivar that was until recently extensively grown in Western Australia, was reported as having minor seedling ...
