Мета. Проаналізувати помилки, які допускають сторони в документах про передачу прав на сорти рослин при неправильному застосуванні заявниками та авторами сорту норм чинного законодавства в частині складання документів заявки на сорт рослини та додатків до неї; впорядкувати та розробити практичні рекомендації при укладанні правочинів про передачу прав на сорти рослин. Результати. Виявлено, що чинним законодавством передбачено укладання тільки двох видів договорів у сфері охорони прав на сорти рослин, якими не повністю забезпечуються права та інтереси сторін. Укладання договору про передачу права на подання заявки на сорт рослин є інструментом захисту прав заявників та підставою для прийняття її уповноваженим органом. Висновки. Оформлення документів заявки без помилок сприяє швидкому проведенню формальної експертизи та прийняттю позитивного для заявника рішення. Правильне оформлення трудових угод між селекціонером (автором) та роботодавцем сприяє захисту прав кожного з учасників таких угод.

Species in the order Rhytismatales M.E. Barr ex Minter (Leotiomycetes, Ascomycota) develop on a wide range of host plants, but prefer conifers, such as species of Cupressaceae and Pinaceae. Conifers, the largest group of gymnosperms, show a high diversity in China. In this study, the species diversity of Rhytismatales on twigs of conifers is investigated based on specimens newly collected in China. Morphological characteristics combined with multi-gene phylogenetic analysis (ITS, nrLSU, and mtSSU rDNA) revealed 18 new species, belonging to six new genera (Abiomyces, Cryptococcomyces, Labivalidus, Neotherrya, Pseudococcomyces, and Stipamyces) and three known genera (Hypoderma, Hypohelion, and Tryblidiopsis). Additionally, seven new combinations are proposed. The findings underscore the complexity of fungal taxonomy within Rhytismatales and the importance of considering multiple criteria for accurate classification. The study also explores the importance of host specificity for genus and species delimitation within the order. A key to genera and species of Rhytismatales on twigs of conifers worldwide is provided.

Purpose. Reviewing a history of formation and current state of the national nomenclature and streamlining the Ukrainian scientific species names for the genus Fragaria L. Results. Controversial attitudes towards the use of names «sunytsi» (= garden strawberry) and «polunytsi» (= hill strawberry) are inherently present in the Ukrainian nomenclature of the genus Fragaria L. The Ukrainian scientific names of species of this group of plants should be brought into line with the generic name “Sunytsi” in plural. Nothogeneric name x Fragophora Mezhenskyj (= Dasiphora Rafin. x Fragaria L.) is proposed. Conclusions. In a professional environment it is necessary to use only scientific names of species of the genus Fragaria – Sunytsi (= garden strawberry) that is used in plural in Ukrainian. Concerning garden strawberry, in every day life and popular literature the usage of a derivative sunytsia (in Ukrainian) in singular as well as polunytsia, polunytsi (in Ukrainian) may be permissible.

Purpose. Studying the norm of reaction of vegetable bean varieties depending on the feeding area, namely the row width. Methods. Field, biometriс, statistical, laboratory ones. Results. ‘Karadag’ (k), ‘Windsorski’, ‘Bartoli’ and ‘Karestino’ varieties were trialed during 2012–2014. In the course of trial the peculiarities were studied concerning the formation of plant height, the number of beans and seed weight of vegetable bean varieties depending on the row width in the phase of technical maturity of the beans. It was found that differential of plant height growth was changed to a greater degree in ‘Windsorsky’ variety (+9,3 cm for every 10 cm) in case of row width narrowing from 60 to 20 cm. ‘Windsorsky’ variety had the largest number of beans and the highest seed weight per plant – 8.9 beans and 14.44 g respectively. Seeds of ‘Karestino’ variety were large, their weight per plant made up 10.56 g, the number of beans totaled to 6.6. Conclusions. The maximum influence of feeding area on a height of plants was found in the phase of technical maturity of beans. The largest increase in plant height for every 10 cm of row spacing was observed in ‘Karadag’ and ‘Windsorski’ varieties. The number of beans also is depended on feeding area. With its reducing, the number of beans and their weight per plant was also reduced in all variants. The largest number of beans and the highest seed weight per plant were in variants with feeding area of 1200 cm2 (row width was 60 cm).
