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

The study of vernalization requierement of winter bread wheat 87 modem varieties from Ukraine and Russia showed significant domination - 81.6% - of varieties with short vernalization requierement (30-40 days). Vernalization requierement differences among varieties from different climatic zones were revealed.

Abstract 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.

The untypical weather conditions during the extrema drought in 1993- 1994 have been described. Regularities of the accumulation and spending of the dry substance in leaves of varieties, signi ficantly different in productivity, weke considered depending on weather conditions.

The article highlights the state of breeding and variety studying for Callistephus chinensis in Ukraine and, in particular, in the Horticulture Institute of NAA, and offers the summary of studying the growth and development aspects for Callistephus, various varieties productivity level, their response to specific set of weather and climatic conditions. The research objectives and methods for their achieving are disclosed, as well the requirements a variety shall comply with, namely: reaching homozygote state, distinctness and ornamentality, fusariose and weather conditions resistance. 11 descriptions for new varieties of annual aster (Anastasia, Angelina, Litnia Nich, Lybid, Oksamyt, Samanta, Sofia, Snizhana, Flamingo , Shokoladka, Tsarivna) as bred by the Horticulture Institute of NAAS were provided, namely by identification and economic and biologic characteristics, these varieties are listed in the State Register of Plant Varieties Suitable for Dissemination in Ukraine.

Development of the Variety Research Network under the State System on Right Protection for Plant Varieties during centuries of XX- XXI, was described in the article. On the comprehensive level, main problems and the ways to their solving were determined, a role of the State Service on Right Protection for Plant Varieties in settling of the problem of State food security was demonstrated.

Morphological and cultivation value characteristics description of new perspective ornamental peach varieties bred in Nikita Botanical Gardens has been given. The varieties were bred as a result of using genoplasm Persica vulgaris Mill, varieties with different type of flower, P. mira (Koehne) Koval, et Kostina and Amygdalus communis L. They differ in high ornamental idices in flowering period and in bioecilogical indexes.

Creation of Initial raw for breeding of winter wheat by change of the development type under low temperatures influence was described. Seeds of spring wheat were vernalized in aluminum weighting bottle. By using low temperatures at sawing of M2-6 at the begin ind of optimal terms of sawing of winter wheat, new winter-hardy variety of Voloshkova was bred.

Мета. Вивчити морфологічні й цитологічні особливості пиляків, пилку та маточок рослин роду Miscanthus, отриманих в умовах in vitro. Методи. Препарати маточок, незапліднених насіннєвих зачатків, пиляків та пилку, незабарвлені або забарвлені розчином карміну (2%) в оцтовій кислоті (45%) чи розчином метиленового синього, досліджували методом світлової мікроскопії. Вимірювання для рослин різних видів міскантусу, а також підрахунок кількості пилку різного діаметра здійснювали в десятиразовому повторенні. Результати. Вивчено морфологічні й цитологічні особливості генеративних органів китайського, цукроквіткового та гігантського видів міскантусу. Встановлено, що квітка цієї рослини однодомна, містить як тичинки, так і маточку. Забарвлення пиляків жовте або рожево-жовте, їхні тканини складаються з видовжених клітин довжиною 70–100 мкм. Маточка має зав’язь з двома стовпчиками, що несуть довгі (2,0–2,8 мм) перисті приймочки, колір яких варіюється від білого до яскраво-рожевого. Форма пір’ячок маточки помірно розгалужена; довжина – 160–300 мкм; ширина – 20–30 мкм; розташування почергове; кількість маленьких відгалужень становить 10–15 шт. Пилок різних видів міскантусу відрізняється за якісними та кількісними ознаками, зокрема у M. sinensis і M. sacchariflorus він характеризується округлою формою, вирівняністю та однорідністю (43–48 мкм у діаметрі), а в M. giganteus є більш гетерогенним за розміром (діаметр 23–45 мкм). Пилок має одну округлу орнаментовану пору діаметром 2,7–4,0 мкм. Висновки. За результатами проведених досліджень надано морфологічну та цитологічну характеристику генеративних органів рослин M. sinensis, M. sacchariflorus, M. giganteus, а саме: маточок, пиляків і пилку. Дані, що отримано, слід враховувати в подальшій селекційній роботі у процесі створення ди- та триплоїдних гібридів міскантусу.
