The harmful organisms affecting potato cause great economic damage in all areas where the crop is grown. One of the most economically important pathogens is the potato late blight (agent Phytophthora infestans Mont. (de Bary)). Also, Potato Virus Y (PVY) and potato cyst nematode (PCN) of the Ro1 pathotype, the only one that occurs in the Russian Federation, cause significant yield losses. Materials and methods. Phytopathological and molecular screening was carried out on original interspecific potato hybrids obtained in 11 crossing combinations, seven of which were studied for the first time. Hybrids resulted from crosses that involved Mexican and South American potato species as sources of late blight and PVY resistance. Field observations of late blight resistance were conducted during three seasons under high infection pressure. A part of plant material was screened in laboratory tests. PCR tests employed 9 DNA markers of genes associated with resistance to Ph. infestans, PVY and PCN of Ro1 pathotype used in our previous study. Results. In field evaluation, hybrid clones mostly expressed high, and a part of them moderate late blight resistance. Of the 6 markers of the used Rpi genes, at least two were detected in most clones, while some had 3 or 4 markers. Some clones were found to have markers of PCN resistance genes and of several genes for resistance to PVY. The cytoplasm type was determined for all plant material. Conclutions. Within a small but pedigree-diverse set of interspeсific hybrids, the markers of resistance genes to all three pests were found. A part of clones obtained by using the sources of PVY and late blight resistance which we had identified, were found to contain two or more resistance genes to these pathogens. According to the results of molecular tests, the clones were found to carry several markers of late blight and PVY resistance genes. Original interspecific potato hybrids with determined late blight resistance levels, cytoplasm type and availability of markers of genes for resistance to three pests can be used in further hybridization.","PeriodicalId":20582,"journal":{"name":"Plant breeding and biotechnology","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84057974","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}

The main objective of this branch is the creation of plants that are attractive to the consumer and commercially characterized by such valuable biological features as adaptability, resistance to diseases, pests, frost and others. Most ornamental plant varieties were bred by means of traditional breeding methods such as selection, distant hybridization, clone breeding, radiation and chemically induced mutagenesis. However, the use of traditional breeding tools is limited by the potential for intraspecific variability. The development of modern biotechnological and genetic approaches to the breeding of new varieties has made it possible to modify the plant genotype at a qualitatively new level. The present review covers the directions in and methodology of modern ornamental plant breeding in Russia, ways of mobilizing the genetic resources of the main ornamental crops such as rose, clematis, canna, chrysanthemum, pelargonia, iris, daylily, tulip, lilac, and rhododendron. Aslo, the review offers examples of ornamental plant breeding work uderway in the leading specialized scientific institutions such as the Russian State Agrarian University – the K.A. Timiryazev Moscow Agricultural Academy, I.V.

{"title":"Molecular screening of the VIR strawberry varieties collection for the presence of a marker for the anthracnose black rot resistance gene Rca2","authors":"I. E. Khrabrov, O. Antonova, M. Shapovalov, L. G. Semenova","doi":"10.30901/2658-6266-2021-4-o3","DOIUrl":"https://doi.org/10.30901/2658-6266-2021-4-o3","url":null,"abstract":"Background. Anthracnose black rot caused by the phytopathogenic fungus Colletotrichum acutatum Simmonds became an extremely harmful disease of strawberries in Southern Russia. The disease is widespread throughout the world, and relatively recently it appeared in Russia. Yield losses due to the disease reach up to 80%; besides, the pathogen causes significant plant losses in mother plantations. The most reliable protection against the pathogen is the cultivation of resistant varieties. In strawberries, resistance is controlled by different genes, including Rca2. To identify this gene, molecular markers STS_Rca2_240 and STS-Rca2_417 have been developed. The purpose of this study was to use the markers for screening the VIR collection of strawberry varieties at the VIR Maikop Experiment Station (Maikop ES VIR). Material and methods. The present work studied 135 varieties of Fragaria × ananassa (Duchesne ex Weston) Duchesne ex Rozier, 83 domestic and 52 foreign ones. The domestic varieties included 17 created at the Maikop ES. Plants were evaluated for anthracnose field resistance in the Republic of Adygea from 2018 to 2021. Molecular screening was performed using STS_Rca2_240 and STS-Rca2_417, the molecular markers closely linked to the Rca2 gene. Microsatellite primers EMFv020 were used to control the PCR. The cultivar ‘Sudarushka’, in which the presence of STS_Rca2_240 marker was described in the literature, served as a positive control. Results and discussion. The marker Rca2_240 was detected in 22 cultivars from 135 studied. Among domestic varieties, the frequency of the marker was 18.1%, while among the foreign varieties it was slightly lower and amounted to 13.0%. Among the 17 varieties created at the Maykop SE, the marker was found in three: ‘Majkopskaya rannyaya’, ‘Peryt’, and ‘Shapsugskaya’. The association of the diagnostic fragment with resistance was 73.0%. The marker efficiency was not very high due to the significant number of resistant varieties which do not generate the diagnostic fragments. The resistance in such varieties can be provided by other genes, for example, FaRCa1. The STS-Rca2_417 marker was not effective during screening. Conclusion. Twenty-two varieties with the STS_Rca2_240 marker were identified in the VIR collection, maintained at the Maykop ES VIR, 16 of which were resistant to C. acutatum. These varieties represent a valuable breeding material. The STS-Rca2_240 marker can be used as an important diagnostic trait for the certification of varieties.","PeriodicalId":20582,"journal":{"name":"Plant breeding and biotechnology","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89511021","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}
