In May 2023, surveys were conducted in the barley growing areas of Central district, Baykan, Kurtalan, Pervari, Şirvan, Eruh, and Tillo districts Siirt province, Türkiye. Leaf diseases occurring wild (Hordeum spontaneum, Hordeum bulbosum) plants determined. On plants, net spot forms blotch disease caused by Pyrenophora teres f. teres, maculata, powdery mildew Blumeria graminis sp. hordei, scald Rhynchosporium commune, stripe graminea Cochliobolus sativus detected. form brown rust Puccinia...
Powdery mildew, net blotch, scald, spot barley stripe, and leaf rust are important foliar fungal pathogens of barley. Fungal negatively affect the yield quality in plant. Virulence changes, which can occur various ways, may render resistant plants to susceptible ones. Factors such as mutation, population size random genetic drift, gene genotype flow, reproduction mating systems, selection imposed by major resistance, quantitative resistance diversity pathogenic fungi. The use fungicide or...
Edirne il ve ilçelerindeki arpa buğday ekiliş alanlarındaki yaprak hastalıklarını tespit etmek amacıyla 1-5 Mayıs 2018 tarihleri arasında sürvey yapılmıştır. İncelenen tarlalarında Septoria tritici, Puccinia striiformis f. sp. recondita Blumeria graminis tritici Pyrenophora tritici-repentis tarafından meydana getirilen hastalıklar görülmüştür. ilindeki en yaygın hastalık lekesi hastalığı olarak bulunmuş olup bu kahverengi pas, sarı külleme hastalıkları takip etmiştir. teres teres,...
Spot form net blotch, caused by
Net blotch foliar diseases of barley are important in Turkey, lowering grain yields and quality. There two forms, the spot form (caused by Pyrenophora teres f. maculata ( Ptm )) net P. Ptt . To determine pathotypes surveys were carried out during 2012, 2013 2015. samples collected from 34 provinces Turkey. From these samples, 258 167 single conidium isolates obtained. Pathotypes 50 40 assessed inoculating onto a differential set 25 genotypes. Twenty six 24 identified, significant pathogenic...
Seedling reactions of 20 barley cultivars grown in Turkey were determined under greenhouse conditions to six isolates Drechslera teres f. maculata, the causal agent spot form net blotch disease.Isolates obtained from different provinces Turkey.Differences among fungus observed.Isolate differences pathogenicity for each cultivar also present.The ranged between susceptible resistant.Reaction Bülbül 89 moderately susceptible.Barley cvs Obruk 86 and Anadolu exhibited susceptible-susceptible...
Pyrenophora teres f. maculata (Ptm) and (Ptt) causes spot form net of blotch diseases barley, respectively.Although both forms P. are morphologically similar, their symptoms genetic background differ.In this study, 175 single spore (109 Ptm 66 Ptt) isolates obtained from different regions Turkey were evaluated for mating type distribution prevalence.Fungal verified using species-specific polymerase chain reaction (PCR) primers.For determination studies, duplex PCR was performed MAT-specific...
Pyrenophora teres f. maculata (Ptm) and (Ptt) incite net spot forms of blotch disease barley, respectively.In this study, Ptm Ptt isolates differing in virulence were compared terms protease activity glucose production.Protease production by ranged between 75.33 ± 4.10 127.33 7.54 unit (U) mg -1 protein.Virulent produced significantly more than the less virulent isolates.Similarly, 0.55 0.03 0.84 0.05 g mycelial dry weight (DW).Virulent also isolates.Similar results obtained with...
Pyrenophora graminea is the seed-borne pathogen causal agent of barley leaf stripe disease. In this work, we screened a collection 206 spring two-row cultivars from Europe for their resistance to fungal pathogen. Artificial inoculation with highly virulent isolate Dg2 revealed continuous variation incidence infection, few resistant or susceptible genotypes. On average, old showed higher than more modern ones. Genome-Wide Association Scan was performed by exploiting available molecular data...
Bu çalışma ile Kırıkkale ili arpa ve buğday tarlalarında görülen yaprak hastalıkları belirlenmiştir. 2015 yılında ilinin merkezi 8 ilçesinde sürvey çalışmaları yürütülmüş hastalıkların yaygınlıkları şiddetleri 128 tarlası 172 olmak üzere toplam 300 tarla incelenmiştir. İncelenen Drechslera teres f. maculata , graminea Rhynchosporium commune Erysiphe graminis sp. hordei Puccinia striiformis tritici tarafından oluşturulan hastalıklara rastlanmıştır. Belirlenen bu yaygınlık oranları ortalama...
Leaf diseases occurring on barley fields in Bala district of Ankara province, Turkey were determined.Survey studies carried out 2018 and prevalence severity these determined.A total 50 examined.The following disease causing agents found: Drechslera teres f. maculata, teres, graminea, Rhynchosporium secalis Erysiphe graminis sp.hordei.Mean prevalences determined as 30.7%,Drechslera maculata 11.7%, graminea 1.16%, 4.67% sp.Hordei 0.2%.Drechslera found the most common agents.Disease values...
Wild barley (Hordeum spontaneum) is a progenitor of cultivated and naturally grows in Turkey. H. spontaneum genotypes possess superior characteristics for biotic abiotic stress tolerance factors. In this study, 3 virulent Pyrenophora teres f. maculata P. isolates were tested under greenhouse conditions order to find net blotch resistant genotypes. A total 104 used. Twenty-six which corresponded 25% the (genotypes numbered 8, 13, 14, 16, 22, 24, 27, 31, 37, 44, 47, 54, 58, 62, 65, 66, 69, 74,...
Unimproved landraces and wild relatives of crops are sources genetic diversity that were lost post domestication in modern breeding programs. To tap into this rich resource, genome-wide association studies large plant genomes have enabled the rapid characterization desired traits from natural landrace populations. Wild barley (Hordeum spontaneum), progenitor domesticated vulgare), is dispersed across Asia North Africa, has co-evolved with ascomycetous fungal pathogens Pyrenophora teres f. P....
Pyrenophora teres is an important pathogen of barley. The has two biotypes: f. , which causes the net type blotch, and P. maculata causing spot blotch. Turkey gene centre barley a rich landrace population. Finding disease resistant germplasm potential for world agriculture. Three virulent ( Ptm ) isolates three Ptt were tested their pathogenicity to 198 landraces, landraces both forms identified. Thirteen (numbered 17, 40, 71, 98, 101, 103, 104, 143, 162, 167, 171, 183 185) seven 18, 21, 22,...
Net blotch caused by Pyrenophora teres is an important pathogen of barley plants worldwide. There are two biotypes the fungus. f. (Ptt) causes net form disease and maculata (Ptm) spot disease. Barley landraces good sources resistance. In this study, seedling response 25 obtained from different regions northwest Iran to 3 single spore isolates Ptt Ptm were determined under greenhouse conditions. Differences in virulence among evident. Some showed responses isolates. Landraces # 9 16...
