Abstract:
Wheat (Triticum sp. L.), as one of the first domesticated food crops, is the basic staple food for a large segment of population around the world. The crop though is susceptible to many fungal pathogens. Stripe rust is an important airborne disease caused by Puccinia striiformis (Pst) and is widespread wherever wheat is cultivated throughout the world, in temperate-cool and wet environments. The causal fungus of stripe rust or yellow rust is an obligate parasite that requires another living host to complete its life cycle. Pst includes five types of spores in the life cycle on two distinct hosts. Stripe rust is distinguished from other rusts by the dusty yellow lesions that grow systemically in the form of streaks between veins and on leaf sheaths. The importance and occurrence of stripe rust disease varies in cultivated wheat, depending on environmental conditions (moisture, temperature, and wind), inoculum levels and susceptible host varieties. Transcaucasia was previously thought to be the center of origin for the pathogen. However, new findings further underlined Himalayan and near-Himalayan regions as center of diversity and a more tenable center of origin for P. striiformis. Long-distance dispersal of stripe rust pathogen in the air and occasionally by human activities enables Pst to spread to new geographical areas. This disease affects quality and yield of wheat crop. Early seeding, foliar fungicide application and cultivation of resistant varieties are the main strategies for its control. The emergence of new races of Pst with high epidemic potential which can adapt to warmer temperatures has expanded virulence profiles. Subsequently, races are more aggressive than those previously characterized. These findings emphasize the need for more breeding efforts of resistant varieties and reinforcement of other management practices to prevent and overcome stripe rust epidemic around the world.

Abstract:
The occurrence and virulence of wheat yellow rust in Hungary was studied in the period of 1999–2001. Yellow rust in Hungary occurred only in traces in 1999, strongly spread and reached epidemic level in Röjtökmuzsaj (West Hungary) in 2000, and the epidemic explosion was in the whole country in 2001. Surveys of yellow rust showed the importance of pathotypes, whose virulence spectra (virulent for Yr2, Yr3, Yr6, Yr7, Yr8, Yr9, Yr17, YrA+, YrCV, YrSD) were able to math the unknown resistance genes. Among 78 Hungarian and foreign cultivars 29 were strongly infected by yellow rust.

The article describes the benefits of using plant resistance inducers on cereal crops and the basic principles of their impact on pests development (Pyrenophora tritici-repentis, Puccinia triticina, Puccinia striiformis, Puccinia graminis, Puccinia hordei). The assessment results of the biological and economic effectiveness of L-479 and DL-59 preparations are presented in comparison with the chemical Kolosal,CE and biological Albit, which were used as standards for reducing the development of yellow leaf spot and rust diseases. L-479 product was found to be the most effective on wheat against brown, yellow and stem rust, and yellow leaf spot. Its biological efficacy ranged from 48.3 % to 57.0 % depending on the pathogen, and the increase in grain yield ranged from 3.7 % to 22.1 %. DL-59 product showed the best biological efficacy against dwarf leaf rust of barley – 89.8 %, the increase in grain yield was 3.5 %.

Abstract:
Wheat rusts are the significant diseases of wheat crop and potential threats worldwide. Among all major wheat diseases occurring in all wheat growing areas of the world, yellow rust caused by Puccinia striiformis f. sp. tritici is a big hazard when it occurs in severe condition. The susceptible germplasm and conducive environmental conditions contribute towards wide outbreak of rust diseases. In the present study, eight wheat lines were screened out and correlated with epidemiological factors (temperature, relative humidity, rainfall and wind speed). Results showed that maximum disease severity was observed at minimum and maximum temperature ranging from 13.7-16.7 and 23.5-27.65 0C respectively. Their disease severity was increased with increase in relative humidity ranging from 52-64 %. Similarly, rain fall ranging from 5.7-21.99 mm and wind speed 6.88-11.73 km/h respectively proved conducive for yellow rust development in Sargodha. A positive correlation was observed between disease severity and all environmental factors.

Kharouf, Sh., Sh. Hamzeh and M.F. Azmeh. 2021. Races Identification of Wheat Rusts in Syria during the 2019 Growing Season. Arab Journal of Plant Protection, 39(1): 1-13. Wheat rust diseases, caused by Puccinia striiformis f. sp. tritici (stripe or yellow rust), P. triticina f. sp. tritici (leaf or brown rust) and P. graminis f. sp. tritici (stem or black rust) are important factors affecting both durum and bread wheat production in Syria. Considerable losses were caused by these diseases, especially stripe rust, estimated at more than one million metric tons, in the 2010 season, out of 5 million anticipated production. Therefore, it is essential to monitor and follow the movement of these three rust physiological races. In the 2019 growing season, 165 wheat fields were surveyed, and 312 samples were collected and characterized. Ten races of stripe rust were identified in ten locations, of which, four represent new record in Syria, namely the races 16E154, 69E150, 264E46 and 258E64. In addition, four races of leaf rust were identified in four locations, one of which (BKLP) is a new record in Syria. In addition, three previously recorded stem rust races were identified from three different locations. It should be mentioned that the newly recorded races of stripe rust are able to overcome resistance genes Yr1 and Yr5, on which the resistance of durum wheat cultivars such as "Cham3" depended, with a disease severity of 40S recorded in the same locations. It is also worth noting that the stripe rust race 462E128 (warrior) was not detected in the isolates studied. Likewise, the stem rust race Ug99 was also not identified, and because of the aggressiveness of this race, continuous inspection through field surveys accompanied with pathogenicity tests is essential during the coming seasons.

Abstract:
The potential of hyperspectral reflectance data was explored to assess severity of yellow rust disease (Biotroph Pucciniastriiformis) of winter wheat in the present study. The hyperspectral remote sensing data was collected for winter wheat (Triticum aestivum L.) cropat different levels of disease infestation using field spectroradiometer over the spectral range of 350 to 2500 nm. The partial least squares (PLS) and multiple linear (MLR) regression techniques were used to identify suitable bands and develop spectral models for assessing severity of yellow rust disease in winter wheat crop. The PLS model based on the full spectral range and n = 36, yielded a coefficient of determination (R2) of 0.96, a standard error of cross validation (SECV) of 12.74 and a root mean square error of cross validation (RMSECV) of 12.41. The validation analysis of this PLS model yielded r2 as 0.93 with a SEP (Standard Error of Prediction) of 7.80 and a RMSEP (Root Mean Square Error of prediction) of 7.46. The loading weights of latent variables from PLS model were used to identify sensitive wavelengths. To assess their suitability multiple linear regression (MLR) model was applied on these wavelengths which resulted in a MLR model with three identified wavelength bands (428 nm, 672 nm and 1399 nm). MLR model yielded acceptable results in the form of r2 as 0.89 for calibration and 0.90 for validation with SEP of 3.90 and RMSEP of 3.70. The result showed that the developed model had a great potential for precise delineation and detection of yellow rust disease in winter wheat crop.

Abstract:
It is important to understand the underlying plant defense mechanisms in order to establish best strategies to reduce losses due to diseases in cereals. The current available information is mostly on model organisms and their plant-pathogen interactions. However, this study is focused on the identification of genes involved in the resistance mechanism of one of the most devastating diseases of wheat, yellow rust. The strategy undertaken was to use differential display method (DD) together with microarray technology, on yellow rust differential lines of wheat (Avocet-Yr1 and Avocet-Yr10) infected with the virulent and avirulent Puccinia striiformis f. sp. tritici races (Pst: PST17, PST45, 169E136 and 232E137) together with appropriate control infections. DD primer combinations of ninety allowed the detection of fourteen differentially expressed genes which were also confirmed by real-time QRT-PCR analysis. All of but one were found to be novel sequences in wheat genome. Among those, two very important genes were identified as full ORF including 5&rsquo
and 3&rsquo
end untranslated regions (UTR)
namely cyclophilin like protein (putative antifungal activity) and ubiquitin conjugating enzyme (E2). The sequence homology analysis of the cloned gene fragments reveled that the genes detected have roles in ubiquitinylation, programmed cell death (apoptosis), putative antifungal activities, disease resistance, pathogen related responses, including a few with no known function. In addition to DD analysis, using wheat Affymetrix &ldquo
GeneChip&rdquo
, we identified 93 differentially expressed ESTs of wheat in response to avirulent pathogen attack. We also investigated the differential expression profiles of wheat leaves during the virulent infections and determined 75 differentially regulated ESTs. 1Selected ESTs were further analyzed using QRT-PCR analysis and 15 were confirmed to be differentially regulated. For the further characterization of the identified genes, such as determination of their putative roles in disease response, functional studies have to be performed. For this purpose, BSMV (Barley Stripe Mosaic Virus) mediated virus induced gene silencing (VIGS) method is optimized in this thesis for wheat. We have successfully managed to silence the endogenous PDS gene (Phytoene desaturase) of wheat which can be used as a positive control for the monitoring of silencing of the genes we have identified. Our results show that BSMV mediated VIGS can be used efficiently and effectively to silence wheat genes that we identified through differential display and microarray analysis and can be used to study the functions of those genes

Abstract:
Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is an economically important foliar disease of wheat (Triticum aestivum). In the last decade, losses from stripe rust in North Dakota (ND) have increased, peaking at 5% in 2015. Three research studies were conducted to address questions on the pathogen, varietal resistance, and integrated management. The objective of the first study was to (i) identify virulent phenotypes of Pst isolates collected from ND from 2015 to 2017 and assign races, and (ii) determine the effect of temperature on in vitro urediniospore germination, latency, and lesion spread. Across the three years, five races were detected with PSTv 37 being the most common. The highest urediniospore germination occurred at 12oC followed by 16oC. Pst isolates had shorter latency at 21oC and larger lesion spread at 16oC. The objective of the second study was to evaluate seedling resistance and adult plant resistance in the North Dakota State University spring wheat breeding program using races PSTv 37 and PSTv 52. Results from seedling experiments indicated only four and two lines were resistant to PSTv 52 and PSTv 37, respectively. Adult plant resistance experiments were unsuccessful in 2019, and will be conducted again in the future. The objective of the third study was to develop fungicide timing recommendations for wheat rust (stripe and leaf) based on varietal resistance and time of disease onset. Rust developed in five of the eight field trials, and timing of disease onset was categorized by growth stage (tillering, flag leaf, or early-flowering). Results indicated fungicide application timing was influenced by timing of disease onset and varietal resistance. When rust was detected at the tillering growth stage on the susceptible variety, the best time to apply a fungicide was at Feekes 9. When rust was detected at flag leaf or beyond on a susceptible variety, a fungicide application at Feekes 10.51 provided the adequate disease reduction and protection of yield. Results from these research studies provide a better understanding of Pst, determined seedling resistance in the breeding program, and provides field data to refine management recommendations for wheat rusts in ND.

Abstract:
Stem rust and Yellow rust diseases are the two major wheat fungal diseases causing considerable yield losses in Turkey and all around the world. There are studies which are carried out to identify and utilize resistance sources in order to obtain resistant lines of wheat. However, virulent pathotypes are continuously being important threats to wheat production and yield. For that reason, new approaches for rapid identification are needed. The aim of this study was to investigate and to understand the structural and functional differences between the resistant and sensitive durum wheat cultivars to the plant fungal diseases of stem and yellow (stripe) rusts. To aim this, forty durum wheat recombinant inbred lines (RILs), which were previously determined to be resistant or sensitive to stem and yellow rust diseases, were investigated by the noninvasive Attenuated Total Reflectance Fourier Transform Infrared (ATR-FTIR) Spectroscopy. Also, classification of the resistant and sensitive lines depending on the structural and functional differences has been attempted. The FTIR spectra for stem rust disease showed that, resistant durum wheat lines had a significant increase in the population of unsaturation in acyl chains of lipid molecules, an increase in lipid and in total protein content and also an increase in carboxylic acids and alcohols. For yellow rust disease, resistant lines had a significant increase in hydrogen bonding and they had also a more ordered membrane structure. In Principal Component Analysis for stem rust disease, according to 3700-650 cm-1 region, amide III band (1213-1273 cm-1 region) and C-H stretching region (3020- 2800 cm-1), the resistant and sensitive groups were separated successfully. For yellow rust disease, according to 3700-650 cm-1 region, Amide A and Amide III bands, the resistant and sensitive lines were grouped distinctly. FTIR spectroscopy provides a useful approach to determine the differences in molecular structure of durum wheat RILs regarding resistance of lines to fungal diseases. However, further research is still needed to ensure if the structural and functional differences in biomolecules of the samples could be used as molecular markers for discrimination of rust resistant materials from rust sensitive ones.

Abstract:
Yellow rust resistance in the winter wheat cultivar Claire is considered durable, as Claire has been grown extensively within the UK for over 10 years and the resistance has remained effective. To characterise this potentially durable source of resistance a doubled haploid (DH) population was produced between Claire and the yellow rust susceptible cultivar Lemhi. Construction of a genetic linkage map, together with phenotypic data allowed the estimation of the number, chromosomal position and degree of effect of yellow rust resistant QTL(s). Claire was found to exhibit a quantitative, adult plant resistance phenotype (APR) controlled by two major QTLs, both located on chromosome 2DL (QTLAPR.2Da and QTLAPR.2Db) and two minor QTLs, located on 2BL (QTLAPR.2B) and 7BL (QTLAPR.7B). These QTLs act additively to achieve a resistance response that has remained effective since Claire’s release in 1999. Marker loci associated with the two major QTLs and knowledge of Claire’s pedigree suggests QTLAPR.2Da could be a APR QTL, known to confer complete immunity to yellow rust, originating from the winter wheat cultivar Alcedo and that QTLAPR.2Db is the durable yellow rust resistance gene Yr16 derived from Cappelle-Desprez. However, DH lines containing QTLAPR.2Da exhibited either a complete or partial yellow rust resistance indicating a potential suppressor effect against the resistant phenotype conferred by this major QTL could be segregating within the population. Analysis of transcript levels of defence genes was used to examine the effect of the hypothesized suppressor on the expression of basal defence in DH lines containing QTLAPR.2Da. No correlation between the presence of the hypothesized suppressor and expression of basal defence genes was observed. The identification of four APR QTLs in Claire and a potential suppressor in Lemhi that affects QTLAPR.2Da will serve as a precursor to help elucidate the defence mechanisms of the yellow rust resistance in Claire.

Abstract:
Since 2000, stripe rust, caused by the fungal pathogen (Puccinia striiformis Westend. f.sp. tritici Eriks.) has resulted in yield losses of wheat (Triticum aestivium L.) in the United States, that exceeded the combined losses of leaf rust (Puccinia triticina Eriks.) and stem rust (Puccinia gramins Pers.:Pers f. sp. Tritici Eriks. E. Henn.). The objectives of this study are to identify and map adult plant stripe rust resistance quantitative trait loci (QTL) in soft red winter (SRW) wheat that are effective against race PST-100, which is the predominant race of the pathogen in the eastern U.S. Adult plant resistance (APR) was characterized in the resistant wheat lines â USG 3555â , VA00W-38, and â Coker 9553â . Resistance in each of the lines was evaluated in populations derived from crosses with susceptible lines â Neuseâ , Pioneer Brand â 26R46â , and VA01W-21, respectively. On chromosomes 1AS, 4BL, and 7D of USG 3555, QTL were identified that explain on average 12.8, 73.0, and 13.6 percent of the variation for stripe rust infection type (IT), and 13.5, 72.3, and 10.5 percent of the variation for stripe rust severity. A QTL from Neuse was identified on 3A that on average explains 10.9 percent of the variation for IT and 13.0 percent of the variation for severity. On chromosomes 2AS and 4BL of VA00W-38, QTL were identified that on average explain 58.9 and 19.3 percent of the variation for stripe rust IT, and 51.9 and 12.1 percent of the variation for severity. On chromosomes 6BL and 3BL of Pioneer 26R46, QTL were identified that on average explain 8.9 and 2.1 percent of the variation for IT and 11.7 and 3.9 percent of the variation for severity. Coker 9553 possesses the QTL on 4BL that is also present in USG 3555 and VA00W-38. The SSR markers, Xgwm296, Xbarc163, and Xwmc756 were tightly linked to QTL on chromosomes 2AS, 4BL, and 6BL, respectively, and their use and development of additional diagnostic markers will facilitate the incorporation and pyramiding of stripe rust resistance QTL into SRW wheat lines via marker-assisted selection.

Polyphenol oxidase (PPO) catalyses undesirable darkening in wheat products such as Asian noodles. Genetic variation for PPO activity is characterized in bread wheat. Australian wheat breeding programmes recognize that reduced PPO activity is an important quality target. Despite this interest from breeders, no varieties possessing extremely low and null PPO activity exist. The development of null PPO wheat varieties is dependant on an understanding of the genetic control of the null phenotype. Knowledge of these factors will accelerate efforts to develop them. The inheritance of PPO activity was investigated in two populations that were derived from hybrids between a null PPO genotype and Australian wheat varieties Lang and QAlBis. Observed genetic ratios were consistent with two and three gene control, respectively in these populations. QTL mapping was performed in the QALBis x VAW08-A17 population. The Diversity Array Technology (DArT) approach was employed to genotype the QALBis x VAW08-A17 population. Three highly significant QTLs that control PPO activity were identified on chromosomes 2AL, 2BS and 2DL. Close associations between PPO activity and DArT marker loci wPt-7024, wPt-0094 and wPt-2544 were observed, respectively. Collectively, these loci explained 74% of the observed variation in PPO activity across seasons. Significant QTLs on chromosomes 1B and 3B were also identified that together explained an additional 17% of variation in PPO activity. The relationship between PPO activity and yellow alkaline noodles (YAN) colour stability parameters was investigated in a DM5637*B8 x H45 doubled haploid population. PPO activity and changes in YAN brightness (ΔL* 0-24h) and yellowness (Δb* 0-24h) in both seasons were analysed. Quantitative trait analyses of PPO activity, flour yellowness (b*) and YAN colour stability was also conducted in this population. QTL mapping of variation in PPO activity in the DM5637*B8 x H45 DH population identified a highly significant QTL on chromosome 2AL, which explained 52% of the observed variation across seasons. Regression analysis identified that wPt-7024 was highly significantly associated with PPO activity in this population. A highly significant association between this marker and PPO was also identified in the QALBis x VAW08-A17 population. Collectively, the three identified QTLs (on chromosomes 2AL, 7A and 7B) explained 71% of variation in PPO activity across seasons. A highly significant (P<0.001) QTL on chromosome 2B along with significant (P<0.01) QTLs on the chromosomes 1A, 3B, 4B and 5B were found to control flour yellowness. The QTLs on 2B, 4B and 5B were detected in both seasons analysed and accounted for 90% of variation in flour b* across seasons. The study on YAN colour stability located two highly significant (P<0.001) QTLs and two significant (P<0.01) QTLs that controlled the change in brightness of yellow alkaline noodle. The 2A QTL accounted for 64% of observed variation across seasons. It was in the same location as the PPO QTL and shared a common closest marker wPt-7024. Only one significant QTL for YAN a* (0-24h) was identified. It accounted for 12% of variation across seasons and was only detected in one season. One highly significant (P<0.001) QTL and two significant (P<0.01) QTLs were identified that controlled the change in yellowness of yellow alkaline noodle. The 2A QTL accounted for 68% of observed variation across seasons. The location of this QTL corresponded with that of 2A QTLs for PPO activity and L* of YAN in this study. Furthermore, wPt-7024 was also identified as the marker with the most significant association with L*. The identification of a correlation between the characters and a common location of a highly significant QTL for each of these characters indicates that it is likely that PPO activity is directly responsible for a large proportion of the changes in brightness and yellowness of YAN. QTLs for L* and b* of YAN were detected in a common location on chromosome 1A. However, no corresponding QTL was identified that controls PPO activity, highlighting the complexity of the relationship between these traits. Resistance to three rust pathogens (Puccinia graminis, Puccinia striiformis, and Puccinia triticina) was also investigated in the DM5637*B8 x H45 DH population because they are major yield limiting diseases in wheat. Disease response data at the seedling stage were converted to genotypic scores for rust genes Sr24/Lr24, Sr36, Lr13 and Yr7 to construct a genetic linkage map. No recombination was observed between rust resistance genes Sr36, Lr13 and Yr7 in this DH population. Therefore, these genes mapped in the same position on chromosome 2B. The Lr24/Sr24 locus was incorporated into the chromosome 3D map. Interval mapping analysis identified QTLs on chromosomes 2B, 3B, 4B and 5B that control adult plant resistance (APR) to stripe rust. Two QTLs on chromosomes 2B and 3D were identified that controlled APR to leaf rust in this DH population.

Abstract:
Yellow rust, caused by Puccinia striiformis Wes. is one of the most significant diseases constraint to winter wheat production in the world. Since 2011 in Europe have appeared distinct new races – Warrior, Kranich, Warrior (-) that have caused wide epidemics on different cultivars of wheat. Grain yield losses can be prevented by using a combination of varietal resistance and fungicides. Information on wheat variety susceptibility to local yellow (stripe) rust Puccinia striiformis Wes. races can help to reduce the risk of yield losses in high disease pressure situations. Field trials with eight most popular and perspective winter wheat varieties in Latvia were established in the North-Western part of Latvia (Stende Research Centre) in autumn of 2016. The trial was designed as two randomized complete blocks (treated and untreated) and data were statistically interpreted. Two applications of fungicides at BBCH 29-32 by T1 (prothioconazol 53 g L-1, spiroxamin 224 g L-1, tebucanazole 148 g L-1) and at BBCH 37-39 - T2 (bixafen 65 g L-1, prothioconazol 130 g L-1, fluopyram 65 g L-1- 1.5 L ha-1) were used to control the YR. Yield and 1000 kernel weight (TKW) were determined. Preliminary results indicated the difference between genotypes resistance/susceptibility to YR. The severity of infection level was 1- 80% depending on genotype resistance. Application of fungicides increased grain yield by 2.9 % to 33.0% and TKW by 3.4% - 33.2 % depending on variety. Observations showed the difference in the occurrence of symptoms on YR in different varieties of winter wheat under conditions of 2017 in Stende.

Abstract:
T. miguschovae (GGAADD) was used as a “genetic bridge” to transfer valuable traits to the common wheat instead T. militina and Ae. tauschii. Lines with resistance to leaf rust, yellow rust and powdery mildew, as well as with high protein content (17–18 %) were selected. The lines with translocation Т2BL.2BS-2GL, 5BS.5BL-5GL, T6BS.6BL-6GL and substitution of chromosomes 1D(1Dt), 4D(4Dt), 5D(5Dt), 6D(6Dt) were identified. DNA analysis revealed that the lines can carry leaf rust resistance genes that are different from the known Lr39 and Lr50. Introgression lines have been successfully used in breeding. Five common winter wheat cultivars are developed.

Abstract:
Multifunctional biological products based on strains of microorganisms that are antagonists of pathogens and plant disease resistance activators - chitosan and its derivatives increase the content of chlorophyll α and b in flag leaves of wheat, the number and weight of grains in the ear, potential yield, and also reduce the development of yellow rust. The maximum biological effectiveness for these indicators was noted in the experimental version, where Bacillus subtilis VKM B-2604D and B. subtilis VKM B-2605D strains that are part of the Vitaplan biological product and chitosan salicylate (Chitosan II) complex was used.

Abstract:
Winter wheat is one of the leading agricultural crops in Russia. The most common and epiphytotic pathogen is leaf rust (Puccinia triticina). The aim of the work was to evaluate the effectiveness of known wheat resistance genes to brown rust in the phase of adult plants in the South of Russia. For the study, route surveys were conducted in the conditions of the North Caucasus region, and herbarium material was collected to create an infectious background on the field site of the FSBI “All-Russian Research Institute of Biological Plant Protection”. As a result of the evaluation of 49 isogenic lines of winter wheat, the Lr9, Lr42, Lr43+24 and Lr50 genes with absolute resistance to P. triticina were identified in the South of Russia in 2019. Study of lines with known resistance genes on an infectious background in the field gives an idea of the change in the effectiveness of P. triticina Lr genes.

Abstract:
Puccinia striiformis is a biotrophic pathogen able to cause broad scale epidemics in wheat growing regions. P. striiformis is genetically highly variable pathogen. New, aggressive genetic lineages, adapted to warm temperatures have been observed in the last decades worldwide. The study aimed to ascertain the structure of genetic lineages of P. striiformis in Latvia. Forty one wheat leaf samples with yellow rust symptoms were collected in 2017–2019. Fenotyping and genotyping methods were used for identification of genetic lineages in Global Rust Reference Center, Denmark. Assessments of leaf diseases on winter wheat differentials – ‘Ambition’, ‘Mariboss’, ‘Moro’, ‘Compair’, ‘Rendezvous’, ‘Spalding Prolific’ and local variety ’Fredis’ were made during the research. Five genetic lineages of P. striiformis – PstS4, PstS7, PstS10, PstS13 and PstS14 were found. 56% from the samples belonged to PstS14, 17.1% PstS10, 12.2% PstS4 and PstS7, 2.4% PstS13. Genetic lineages identified from Latvian wheat samples are found in the biggest cereal growing regions in Europe and are able to cause epidemics on wheat. Genetic lineages of P. striiformis from Latvian samples have not been identified before. All differential varieties were infected with P. striiformis in 2017, ‘Ambition’ and ‘Moro’ in 2018, no infection was observed on differentials in 2019 despite the presence of P. striiformis on winter wheat variety ‘Fredis’. The identification of genetic lineages of P. striiformis on wheat in Latvia is necessary to continue.
