In view of the modern context of new trends in the development of science, fundamental knowledge, modern methods and technologies, as well as of climatic and economic challenges, the development of the scientific heritage of N.I. Vavilov plays a big role for scientific and technological development. A total of 185 oral presentations was made at the 5th Vavilov International Conference. Meetings of the Conference attracted over 330 participants. This publication reflects the main objectives and content of the performed activities and contains key recommendations emanating from the Conference, including (1) recommendations for the conservation, study and use of PGR, including those on the multidisciplinary basis; (2) recommendations on activities to ensure coordination in the field of conservation, research, breeding and seed production; (3) recommendations on the normative and legislative regulation in the sphere of breeding, seed production, development, maintenance and use of genetic resource collections; (4) recommendations on training, guidance and education. Presentations made at the Conference show that over the past five years there has been a significant increase in the use of modern methodical approaches, i.e. molecular-genetic, genomic and omics in the field of PGR research. All this provides a solid basis for the development of new breeding methods (Next-Generation Breeding). At the same time, it is emphasized that new breeding technologies based on the acquired knowledge, can lead to further progress not in isolation from, but in conjunction with the amassed heritage of classical breeding. Among the discussed and proposed issues, the Conference Resolution identifies those requiring special and urgent attention: (1) the need to legislate for the preservation and expansion of crop diversity in the State Register of Varieties and Hybrids of Agricultural Plants Approved for Use; (2) the inadmissibility of reducing the list of these crops; (3) the inadmissibility of reducing of the number of state variety testing sites; (4) the inadmissibility of reducing of time limits of state variety testing from three to two years or one year; (5) the need to bring the concepts of “genetic passportˮ and “genetic passportizationˮ used in legal and regulatory acts to the canonical understanding of “genetic passportˮ as a document reflecting individual genetic features of an organism (cultivar/hybrid/breed/strain), which make it possible to distinguish its genotype from that of other organisms (cultivars/hybrids/breeds/ strains) of a particular sp","PeriodicalId":20582,"journal":{"name":"Plant breeding and biotechnology","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75156536","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}

Genetic passport of these five cultivars were carried out according to the new integrated strategy developed at VIR. According to the strategy, the plant material donated by the author of the cultivars to the VIR Herbarium was used for molecular genotyping. Genetic passports included data of allelic composition of eight chromosome specific microsatellite loci, markers of different types of organelle DNA, as well as data about diagnostic fragments of 15 markers of 11 R-genes conferring resistance to the most dangerous diseases and pests of potato: late blight, nematodes, potato X and Y viruses. Data from the developed genetic passports of five Omsk cultivars were compared to the results of genotyping of samples of the same cultivars obtained from different sources. Based on the analysis of pedigrees and genetic passports of these five cultivars we established the origin of their resistance to harmful organisms.","PeriodicalId":20582,"journal":{"name":"Plant breeding and biotechnology","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82629755","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}

Dunaeva, O. Tikhonova, I. Chukhina","doi":"10.30901/2658-6266-2022-4-o5","DOIUrl":"https://doi.org/10.30901/2658-6266-2022-4-o5","url":null,"abstract":"A collection of nomenclatural standards is being created at VIR for domestic cultivars of various crops in accordance with the International Code of Nomenclature for Cultivated Plants (ICNCP). A new complex strategy was proposed for vegetatively propagated crops for registering domestic cultivars received from their authors in the VIR genebank. In addition to the creation of nomenclature standards, the strategy includes the development of a genetic passport of a cultivar and the use of biotechnological methods to preserve explants (buds, meristems) isolated from plant material transferred by breeders to the VIR Herbarium. This approach can be used for any vegetatively propagated crop applying a protocol developed specifically for an individual crop. For raspberry and black currant varieties, the collecting of plant material, its preparation for the registration of nomenclature standards and the preservation of viable samples under controlled in vitro conditions have specific features. This article provides detailed protocols for performing the mentioned work for raspberry and black currant varieties. In addition, the article summarizes the first results of the implementation of our proposed strategy on the example of domestic raspberry and black currant varieties created in various breeding centers of Russia. Three years of joint work of VIR researchers and breeders from four breeding centers in five regions of the country have resulted in creation of nomenclature standards for 20 raspberry varieties, as well as for five black currant varieties bred at VIR. Thirteen samples of raspberry varieties and four of black currant varieties, genetically identical to nomenclature standards, were introduced into in vitro culture; four raspberry cultivars have been placed in the VIR cryobank for the long-term cryopreservation.","PeriodicalId":20582,"journal":{"name":"Plant breeding and biotechnology","volume":"195 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75890052","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}

At the same time, in the south of the country, several zones meet the requirements for peanut cultivation. It is possible to increase the yield of the existing peanut varieties by using modern biotechnology methods, in particular agrobacterial transformation. It is known from the literature data that different peanut genotypes and explants from various sources react differently to in vitro regeneration. Successful regeneration depends on the correct protocol, including both the type of regeneration and the composition of media promoting growth and in vitro induction.Objectives: a technique for obtaining peanut regenerants in in vitro culture.Materials and methods: Eight peanut accessions from the VIR collection of different origin were used in the work. Embryonic explants were grown on Murashige-Skoog medium supplemented with the hormone 2,4-dichlorophenoxyacetic acid (2,4-D).Results and conclusions: As a result of assessing the regenerative ability of peanuts grown on Murashige-Skoog medium with the hormone 2,4-D at a concentration of 2 g/L, differences in the callus formation ability were revealed in different accessions.
