Inheritance of Partial Resistance to Net Blotch in Barley
Plant Breeding, 1990AbstractReciprocal 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 ...

Spring barley accessions with dual spot blotch and net blotch resistance
Canadian Journal of Plant Pathology, 2008Spot 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 ...

Sensitivity of Resistance to Net Blotch in Barley
Journal of Phytopathology, 1999The 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, 1987SUMMARYInoculation 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

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.

Mapping quantitative trait loci associated with barley net blotch resistance
Theoretical and Applied Genetics, 2007Net 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
2018This 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

Genetic studies on net blotch resistance in a barley cross
Canadian Journal of Plant Science, 1996An 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, 1969SUMMARY 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 ...

Diversity among Finnish net blotch isolates and resistance in barley
Euphytica, 1996Seedlings of a differential barley (Hordeum vulgare L.) series (21 genotypes) and of six check genotypes were used in the greenhouse to assess variation in virulence among 20 single-spore isolates of the net blotch pathogen, Pyrenophora teres Drechs. f. teres Smedeg., collected from various sites in Finland.
