The most effective and environmentally safe way to combat wheat diseases is to produce cultivars resistant to their pathogens. For this purpose, old landraces are often used as genetically diverse sources of traits important for breeding. In the process of wheat breeding for resistance to tan spot caused by the fungus Pyrenophora tritici-repentis (Died.) Drechs. (abbr. Ptr), selection is carried out against the dominant allele of Tsn1, the gene of sensitivity to the toxin Ptr ToxA, which induces necrosis and represents the main pathogenicity factor of Ptr controlled by the ToxA gene. The aim of the study was to characterize a set of bread wheat (Triticum aestivum L.) accessions from the VIR collection for resistance to various Ptr populations, genotype these accessions using Xfcp623 – a DNA marker of the Tsn1 gene, and identify sources of tan spot resistance.Materials and methods. Sixty-seven accessions of winter bread wheat landraces were studied. Seedling resistance to two Ptr populations was assessed using a 5-point scale adopted at VIZR. The allelic state of Tsn1 was identified by PCR.Results. Dominant alleles of Tsn1 were found for 55% of the studied accessions. Seventeen accessions were resistant or moderately resistant to two Ptr populations and an isolate from Krasnodar Territory previously used for their characterization. Nine of them had the tsn1tsn1 genotype, and 8 had Tsn1Tsn1. The accessions mainly belonged to three agroecological groups proposed by N. I. Vavilov: “steppe winter bread wheat (Banatka wheats)”, “North European forest awnless bread wheats (Sandomirka wheats)”, and “Caucasian mountain winter bread wheat”.Conclusion. The identified 17 accessions resistant to Ptr are potential breeding sources of resistance. In the studied set of accessions, no significant relationship was found between the allelic state of the Tsn1 gene in the accession and its response to the infection with pathogen populations, including isolates with the ToxA gene.","PeriodicalId":36512,"journal":{"name":"Proceedings on Applied Botany, Genetics and Breeding","volume":"26 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139534364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studying wild-growing grapevines is of interest because it expands the knowledge on the genetic diversity within the gene pool and helps to search for new resistance sources. One of the main differences between wild vines and cultivars is the type of their reproductive system: wild grapes are represented by cross-pollinated dioecious vines, while cultivated ones are, with rare exceptions, hermaphrodites capable of self-pollination. A DNA marker applicable to determine the grape flower sex has been identified.Materials and methods. The VVIB23 DNA marker to the Sex gene determining the flower sex was used to study 36 genotypes of wild-growing grapes selected in 2019–2021 within the Utrish Nature Reserve near Gelendzhik and the Krasny Les State Nature Reserve on the right bank of the Kuban River. PCR technique was applied, and the results were evaluated on a Nanofor 05 genetic analyzer.Results. The studied grapevine accessions were found to be variable for the VVIB23 SSR locus: 7 types of alleles were identified. Alleles corresponding to the male flower type were present in 14 genotypes, and those corresponding to the female type in 21. A PCR fragment whose size, according to the published data, correlated with hermaphroditism was not found, which is typical for wild genotypes.

The use of barley cultivars resistant to greenbug (Schizaphis graminum Rondani) is an effective, economical and ecology-friendly way to control the dangerous phytophage. The insect is able to overcome the resistance of the host plant, which necessitates a relentless search for new genes to ensure reliable protection of barley fields from the pest.Materials and methods. Resistance to the Krasnodar greenbug population was assessed in 345 barley accessions from the Asian part of Russia. Besides, resistance to S. graminum was studied in cv. ‘Post’ (carrier of the Rsg1 gene), a pure line derived from cv. ‘Onokhoisky’ (k-16626, Buryatia) heterogeneous for this trait, and landraces from Mongolia (k-3885, k-3904, and k-4080). Juvenile plants were infested with aphids in the laboratory, and when a susceptible control died, the damage to experimental barley accessions was assessed using a scoring scale. Genetic control of greenbug resistance in the line derived from cv. ‘Onokhoisky’ was studied using the insect’s test clones and an analysis of the segregation in F2 hybrids from crossing the resistant line with cv. ‘Belogorsky’ susceptible to the aphid, when the plants were infested with the Krasnodar population of the phytophage and with clones of S. graminum.Results and conclusions. We identified 7 accessions heterogeneous for aphid resistance. Among them, plants with a high level of greenbug resistance were found in three landraces from Tuva (k-14714, k-14718, and k-14733). Resistance was also clearly expressed in the line derived from cv. ‘Onokhoisky’. This cultivar is protected by a dominant allele that differs from the previously identified Rsg1, as well as from the alleles found in Mongolian landraces k-3904, k-4080, and k-3885. ‘Onokhoisky’ also has genes with low expressivity, which manifest themselves when the main gene for resistance to S. graminum appears ineffective.","PeriodicalId":36512,"journal":{"name":"Proceedings on Applied Botany, Genetics and Breeding","volume":" 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139626025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fire blight (Erwinia amylovora (Burill) Winslow et al.) is a dangerous disease of fruit crops. In the Russian Federation, fire blight is one of the quarantine diseases. Apple resistance to fire blight is controlled polygenically. However, the data on the genotypes of Malus Mill. wild species and varieties in the context of individual resistance loci are scarce. The purpose of the research was studying the genetic collection of apple wild species according to the FBF7 fire blight resistance locus to identify promising sources of resistance to E. amylovora.Materials and methods. The materials of this study included 23 wild and two cultivated apple-tree species (50 accessions) from the genetic collection of the I.V. Michurin FSC. The FBF7 QTL for fire blight resistance was identified with the flanking SCAR-markers AE10-375 and GE-8019, and SSR-marker CH-F7-Fb1.Results and conclusion. The GE-8019 marker was identified in 50.0% of the apple accessions, AE10-375 in 76.0% of the accessions, and CH-F7-Fb1 in 30.0%. Inter- and intraspecific polymorphism of the Malus genus was revealed for the analyzed resistance locus, as well as for individual DNA markers linked to the FBF7 QTL. The GE-8019 and AE10-375 markers flanking the FBF7 QTL were found in 42.0% of the studied genotypes. Meanwhile, three diagnostic markers (GE-8019, AE10-375, and CH-F7-Fb1) were identified only in 7 accessions: M. × robusta var. persicifolia (Carr.) Rehd.

Cowpea is an important legume crop of great nutritional and economic value, ranking fourth in the world among leguminous crops in the area of cultivation. This crop is known to tolerate high temperatures and droughts, so new cowpea cultivars adapted to the local arid conditions of the Lower Volga are of considerable interest.Materials and methods. Mass and individual selection techniques were applied to develop new cultivars from cowpea landraces held in the VIR collection. Selection was carried out at Astrakhan Experiment Station of VIR in 2012–2018, and variety trials took place in 2019–2021.Results. Cvs. ‘Samma Nova’ and ‘Pasta Grin’ were released for vegetable use. The pod yield of ‘Samma Nova’ is 12.18–14.85 t/ha, seed yield is 0.92–1.14 t/ha, protein content is 28.8% in seeds and 27.1% in pods, and its growing season is 57–66 days. The cultivar is bushy, with synchronous pod and seed maturation, suitable for mechanized cultivation. The pod yield of ‘Pasta Grin’ is 24.68–25.84 t/ha, seed yield is 0.82–1.04 t/ha, protein content is 29.1% in pods and 23.6% in seeds. It is a mid-season cultivar, with a rambling stem, intended for growing on a trellis. Both cultivars significantly exceeded the reference (cv. ‘Sibirsky Razmer”) in most of the studied indicators. The breeding work with cowpea accessions showed that pod harvesting at the commercial ripeness stage stimulated plants to develop new pods, which extended the duration of fruiting and increased productivity. The maximum number of pods in all studied cultivars was formed in the first 20 days of the fruiting period.Conclusion. In 2022, according to the results of competitive and local trials, cvs. ‘Samma Nova’ and ‘Pasta Grin’ were included in the State Register for Selection Achievements (National List).

Yellow rust incidence on Triticum L. has been observed to surge up in Dagestan in recent years, facilitating selection of highly resistant genotypes. Information on the effectiveness of Yr genes and the pathogen’s virulence and racial composition is needed to interpret field assessment data correctly. The objective of this study was to describe the virulence of the Dagestan population of Puccinia striiformis West. at the seedling stage, evaluate the resistance of differentiators to yellow rust in the field, and identify invasive PstS1 and PstS2 races.Materials and methods. Leaves with urediniopustules were collected from bread wheat accessions at Dagestan Experiment Station of VIR (DЕS VIR) in 2020–2022. Virulence was analyzed in the laboratory using 14 AvYr lines (Avocet NIL) and 15 differential wheat cultivars. Age-specific resistance of virulence testers under high natural infection pressure was studied in the field of DES VIR. A set of SCAR markers (SCP19M24a1, SCP19M24a2, SCP19M26a1, and SCP19M26a2) were used to identify invasive races.Results and discussion. Avocet lines with Yr5, Yr10, Yr15, Yr24, and Yr26, and cv. ‘Moro’ (Yr10, YrMor) manifested resistance to all isolates. Virulence to Yr17 was detected only in the isolates from cvs. ‘Graf’ and ‘Svarog’ carrying this gene, and ‘Siete Ceros’. The Dagestan collection demonstrated high genetic diversity. Common phenotypes were identified on cv. ‘Graf’ in 2021 and 2020. There was no temporal differentiation between pathogen collections in the years of testing. High field resistance to yellow rust was recorded in lines with Yr5, Yr8, Yr10, Yr15 and Yr24, and in cvs. ‘Moro’, ‘Compair’, ‘Carstens’ and ‘Spaldings Prolific’. Cvs. ‘Reichersberg 42’ and ‘Heines Peko Vilmorin 23’ were resistant in 2020 and 2022, and moderately affected (up to 10%) in 2021.
