“…The studies by A.P. Ermishin (Ermishin, Voronkova, 2015) described a method for obtaining dihaploids of cultivated potato Solanum tuberosum L. (2n = 2x = 24) by using a primitive cultivated potato species S. phureja (2n = 2x = 24) as a haploproducer. The method is based on the phenomenon of pseudogamy, in which both sperms of a pollen grain of a diploid species (n = x = 12) fuse with the central nucleus of the S. tuberosum embryo sac (2n = 4x = 48), which leads to the formation of a hexaploid endosperm.…”

The discovery of the ability of some mutations to stimulate haploidy during hybridization made it possible to create one of the most promising and sought-after trends in the f ield of reproductive biology. Haploid inducers created on their basis are capable of increasing the frequency of haploidy up to 15 %. The improvement of the existing haploid inducer lines and the search for new genes that contribute to a high frequency of haploidy are underway. Along with these studies, the f ield of application of haploid inducers in genetics and plant breeding is expanding. Haploid inducers carrying R1-nj genes for anthocyanin pigmentation of the seed and embryo are able not only to mark the hybrid embryo and identify haploid genotypes, but also to detect genes that suppress the anthocyanin color of the grain, like C1-I, C2-Idf, and In1-D. Depending on their quantity, the phenotypic manifestation of the gene in the seed varies. Haploidy is widely used for accelerating hybrid breeding and obtaining both new maize lines with improved traits and their sterile counterparts. By introducing certain genes into the genome of the improved line, breeders can use the doubled haploid (DH) breeding technology to accelerate the creation of pure lines carrying the desired gene. Haploid inducer maize lines and their tetraploid analogs are used in the selection of rediploid maize lines by their resynthesis from tetraploid genotypes. In 2019, Syngenta Company synthesized a haploid inducer maize line carrying a CRISPR/cas construct capable of simultaneously stimulating haploidy and editing the genome at a specif ied DNA site. Thanks to this technology, it became possible to improve haploid inducers by introducing various CRISPR/cas constructs into the haploid inducer genome for editing any DNA site. Maize haploid inducers are widely used in doubled haploid wheat breeding. The f irst experiments showed that the most effective haploid inducer for stimulating haploidy in wheat is maize pollen. Researchers are intensively searching for other ways of using maize haploid inducers in plant breeding.

“…ГМО значно розширюють можливості традиційної селекції, завдяки чому сьогодні є можливість отримувати організми та їх продукти, що активно використовуються у біотехнології. Однак неконтрольоване створення та використання ГМО пов'язане з певними проблемами біобезпеки й екологічного стану [10,11]. Окрім ГМО, існують інші джерела біологічної небезпеки для населення та навколишнього середовища: віруси, пріони, збудники паразитарних захворювань, природні патогенні мікроорганізми й ті, що набули патогенності в результаті мутагенезу; окремо потрібно враховувати продукти життєдіяльності певних мікроорганізмів (ферменти, токсини тощо).…”

The use of pathogenic and opportunistic biological agents in research and production processes should be accompanied by risk management in the context of biosafety and biosecurity. These issues are regulated differently depending on the industry orientation, including organizational and technical support. To provide a safe environment for working with biological threats of various levels of risks is one of the urgent tasks of our time. Our article is an analytical review of modern approaches to biosafety management in laboratories and industries when working with hazardous biological objects, pollution, including issues of occupational safety management and organizational and technical support of biosecurity. We analyzed the current state of the problem on the implementation and provision of proper working conditions in biotechnological or related industries, as well as in laboratories and research centers operating with biological objects of various hazard classes. To achieve biosafety, the basic principle is to limit or prevent the spread of potentially hazardous or harmful biological agents. The article describes the classification of hazardous biological agents, the current requirements for ensuring biosafety for workers of biotechnological and biopharmaceutical enterprises, laboratories and research centers when working with biological material. Ensuring the appropriate level of biosafety in Ukraine is governed by a number of regulations concerning all areas and activities related to work with biological objects of various hazard levels. Adherence to strict regulatory requirements at all levels of the organization of work in laboratories, research institutions, and industries dealing with biological objects will ensure safe conditions for staff.

. The authors studied the potato collection in 2019-2021 as part of a comprehensive research plan for the implementation of the subprogram “Development of potato breeding and seed production” based on SibNIIRS - a branch of the ICG SB RAS (Siberian Research Institute of Plant Growing and Breeding - a component of the Federal Research Center of the Institute of Cytology and genetics of the Siberian Branch of the Russian Academy of Sciences). The study aims to determine adaptive and high-yield potato varieties and their suitability for breeding. The authors presented the results of a survey of 13 potato varieties distinguished by productivity. The foreign variety Gala was taken as a standard since it is in the top ten cultivated areas in the Russian Federation.In 2019, the standard variety Gala had the highest yield among the tested varieties - 1653 g/bed. In 2020, all the studied varieties exceeded the standard; the authors note the maximum productivity in the following types: Terra (1067 g/bush), Kumach (1076 g/bush), and Prizer (1081 g/bush). In the last year of the study, two varieties significantly exceeded the standard variety: Terra (1280 g/bushel) and Sadon (1377 g/bushel). On average, over three years, the highest productivity was noted in the variety Alaska (1229 g / bush). Over the years of the study, 46% of the studied types distinguished themselves by their high productive ability and had an adaptability coefficient of more than 1. The authors note the highest value of the adaptability index in the variety Alaska (1.07). High marketability of tubers (over 97%) was observed in 11 out of 13 tested types. Low fertility and lack of natural berry formation in widely productive potato varieties make it difficult to use them in breeding for high productivity. In the foreststeppe conditions of the Novosibirsk Priob’ye region, the following types are suitable for breeding for increased productivity as pollinators: Salsa, Signal, and Gala having fertility from 50 to 90%. The authors also noted high natural berry production (7–9 points) in four varieties: Sadon, Prizer, Signal, and Gala. These varieties are recommended for the breeding process as mother plants.
