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.

Interaction of net blotch and scald on barley

Canadian Journal of Plant Pathology, 2008
Abstract Net blotch caused by Pyrenophora teres f. sp. teres and scald caused by Rhynchosporium secalis are major foliar diseases of barley (Hordeum vulgare) and often occur together in the same fields in central Alberta, Canada. The differential development of these two diseases in relation to seeding date was investigated in five field trials in 2001

Field screening for resistance to barley net blotch

Annals of Applied Biology, 1987
SUMMARYInoculation with barley net blotch from infested straw debris was compared with that from diseased plants after sowing infected grains. The straw debris had a high, uniform inoculation potential which gave an early, continuing infection and easily reproducible results that were effective for screening barley cultivars in the field for resistance

Quantitative genetics of net blotch resistance in barley

New Zealand Journal of Agricultural Research, 1985
Abstract A half diallel was made amongst 5 barley (Hordeum vulgare L.) genotypes (Zephyr, Hassan, Mata, Kaniere, and Manchuria) which varied in resistance to net blotch disease, caused by the fungus Drechslera teres (Sacc.) Shoem. The 5 parents and 10 F1 progeny were grown to physiological maturity in a controlled environment.

Net blotch resistance in wild species of Hordeum

Euphytica, 1997
Resistance to net blotch was evaluated in 175 Hordeum vulgare subsp. spontaneum (H. spontaneum) accessions and 149 accessions of thirteen species or subspecies of wild Hordeum. Most H. spontaneum accessions showed resistance to each of the four Pyrenophora teres f. teres (P. teres) isolates tested. However, H.

Diseases affecting barley: net blotches

2018
This chapter reviews the current knowledge of spot form and net form of net blotch of barley with an emphasis on recent genetic studies and their contribution to our understanding of the range of host-pathogen genetic interactions. Principal differences between the two forms of the disease are explained together with common cultural control methods. An

Mapping quantitative trait loci associated with barley net blotch resistance

Theoretical and Applied Genetics, 2007
Net blotch of barley, caused by Pyrenophora teres Drechs., is an important foliar disease worldwide. Deployment of resistant cultivars is the most economic and eco-friendly control method. This report describes mapping of quantitative trait loci (QTL) associated with net blotch resistance in a doubled-haploid (DH) barley population using diversity ...

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 ...
