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.

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

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.

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

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.

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 ...

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

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 ...

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.).

Observations on the Development of Leaf Blotch and Net Blotch of Barley from Barley Debris, 1968

Plant Pathology, 1969
SUMMARY 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 ...
