The article deals with agronomic characters of sugar beet MS hybrids developed on the basis of parental components with resistance to Fusarium rots during vegetation period, which were found in studies with the ecological variety test of Be- taintercross. Possibility of combining high productivity and disease resistance in one genotype was confirmed as matter of principle.

In the Mironivka Institute for wheat named by V.M. Remeslo UAAN new winter-hardy winter wheat variety material was obtained. The annual breeding was used for the selection df winter wheat forms from spring wheat varieties by the prevernalization, spring sowing and M2 at the beginning of optimal terms in autumn (the influence of low temperature on spring wheat seeds). On the basis of such material, winter-hardy wheat varieties were created, such as Myronivs’ka rannyostygla, Remeslivna, Vo- loshkova and such varieties as Bagira, Vdyachna and Svyankova were submitted to the State Service for Plant Variety Protection.

The peculiarities of ice-forming in the stems of 7 cultivars and forms of blackberry have been determined by means of the differential thermal analysis. The authors have established the possibility of controlling the acclimation and loss of frost- resistance by tissues caused by dehydration. The control is possible on the basis of the data about exothermal processes in the tissues.

It was studied the impact of mineral fertilizers on productivity and grain quality of wheat durum spring. Glassiness of grain, protein and gluten contain increase along with increase of doses of nitrogenous fertilizer. Maximum grain productivity was achieved by mineral fertilizers in combination on autumn fallow N60P60K60. after pea - N90P60K60

Quality of Spring Soft Wheat varieties listed in the State Register of Varieties of Ukraine for 2008, according to the grain quality indices (protein content, flour vigor, bread volume). Over 86% of Winter Wheat varieties bred by Ukrainian breeders are classified according to their quality to the strong and valuable, in contrast to 14 % of foreign varieties. This is the evidence of the Ukrainian breeding varieties ability to compete.

This fifth annual edition of MycoNews starts with an editorial on the critical importance of International Mycological Congresses (IMCs) to the health of mycology. Items on Counting down to IMC12, the State of the World’s Plants and Fungi 2023, and progress towards Improving nomenclatural stability in medically important fungi follow. Reports are provided of several mycological meetings in 2023: the Asian Mycological Congress, XIX Congress of European Mycologists, a meeting of European Mycological Groups and Societies, the XI Latin American Mycological Congress, Westerdijk Spring Symposium on Fungal Evolution, the Brazilian Society of Mycology, the Annual Meeting of the Mycological Society of China, and the Fifth Iranian Mycological Congress. Information is provided on how to make nominations for the various IMA Awards due to be presented at IMC12 in August, the new Future is Fungi Award launched in 2023, and the Adel-Azeem and Stamets Award for work on Psilocybe in Africa. The Westerdijk Fungal Biodiversity Institute Awards for 2023 were made to Andrey Yurkov and Cathie Aime and the citations to those awards are provided. We include tributes to the passing of two eminent mycologists, Lorelei Norvell and Takashi Matsushima, and also send birthday greetings to Bryce Kendrick who turned 90, and Maria Ławrynowicz, Yu Li, and Anthony Whalley who all became octogenarians. Reviews of seven mycological books published in 2022–2023 are included in the Book News section.

Firstly in Ukraine as the result of resiprocal interbreedings of autotetraploid (2n=4x=32) / diploid (2n=2x=16) and diploid (2n=2x=16) / autotetraploid (2n=4x=32) four sintetic triploid (2n=3x=24) hybrid forms (611-91, 13-93, 14-93, 18-93) have been obtained. Spontaneous triploid nectarinum 166-80 has been shared out from diploid hybrid seedlings population. Tetraploid and triploid nectarinum forms are valuable sources for directoinal selection and making hybrids with the complex of new signs, which are difficult or impossible to receive on diploid level.

The results of research of the drought tolerance of winter wheat varieties (Triticum aestivum L.), which are suitable for the dissemination in Ukraine are presented. Differentiation of varieties according this trait is made. Groups of varieties were classified. Ways of improvement of the assessment are suggested.

A revised version of Chapter F of the International Code of Nomenclature for algae, fungi, and plants is presented, incorporating amendments approved by the Fungal Nomenclature Session of the 11th International Mycological Congress held in San Juan, Puerto Rico in July 2018. The process leading to the amendments is outlined. Key changes in the San Juan Chapter F are (1) removal of option to use a colon to indicate the sanctioned status of a name, (2) introduction of correctability for incorrectly cited identifiers of names and typifications, and (3) introduction of option to use name identifiers in place of author citations. Examples have been added to aid the interpretation of new Articles and Recommendations, and Examples have also been added to the existing Art. F.3.7 concerning the protection extended to new combinations based on sanctioned names or basionyms of sanctioned names (which has been re-worded), and to Art. F.3.9 concerning typification of names accepted in the sanctioning works.

Methodical approaches to the cutting lettuce new varieties morphological characteristics grouping are found with regard to the botanical classification of the species. New morphological characteristics, used for new varieties of plants grouping and examination for distinctness are defined.
