It is definited the coefficients of quantitative signs’ inheritance for new donors of dominant stem shortness in winter rye. It is proved the genetic conditionality of plant height’s display for three new donors, which s controlled by aditive genes mainly. It is definited the laws of display and inheritance of other utilitarian signs of new donors Gnom 1, Gnom 2 and Gnom 3. The study of genetic associations of paternal forms’ height with the descendants’ quantitative signs enables to define the strategy of selectional use of dominant stem shortness donors in winter rye.

There is the method represented in the article for frost resistance determination for Winter Wheat (soft and hard) varieties by experts’ assessment of varieties submitted for Official Variety Studying. Prescribed temperature limits for artificial freezing of the plants, example varieties for frost-resistance groups, are indicated.

In the article reduced outcomes of the four-years data, concerning influencing the norms of mineral fertilizers, consistency productive stalk-standing density and miscellaneous biotypes of corn on field similarity seeds. Is established, that fullest and friendly derailings was obtained at depositing a full mineral fertilizer in calculation N120P60K60.

The studying results of drought resistance for introdused nectarine varieties in the conditions of South Coast of the Crimea have been given. Four varieties shoved high resistance to drought conditions during two years have been selected.

History of Winter Wheat breeding rise at the South of Ukraine since the end of XIX century till the beginning of October Revolution by the example of Breeding department at Odessa Research Field is represented. Odessa Research Field was established in 1894 to study the agrotechnics of agricultural crops, in particular, Winter Wheat. The Breeding department at Odessa Research Field was established in 8th of March, 1912, and headed by Private- Docent of Novorossiysk University, A.O. Sapegin. The main procedure applied in breeding was individual multifold selection of elite ears from the existing local blends and artificial crossing of lines selected to the purpose of improving economically valuable  characteristics and identifying the inheritance. Five years of breeding (1912-1917 pp.) resulted in creation of three Winter Wheat varieties: Kooperatorka (0194), Zemka (0158) and Stepniachka(0119). In 1918, the Council of People’s Commissars of USSR has parted the Breeding department of Odessa Research Field to independent Odessa agricultural breeding station recognizing development of plant varieties by the Department.

New donors of short-stem dominant characteristic Gnom 1 (G1), Gnom 2 (G2), Gnom 3 (G3) have been created to the purpose of further increasing the yield of Winter Rye and effective redistribution of assimilation products to the benefits of the grain. Genetic and Statistical analysis of 10 selective characteristics of these donors has been conducted and options to improve them were determined. Application of G1 in the prospective breeding programs G1 on 10 characteristics would not create considerable difficulties. Engagement in the crossing of G2 and G3 donors may create complications in the expression of- productivity characteristics of the ear and plants in the progenies. Crossing used in transgress and combinative breeding is preferable for applying. Application of G3 may be accompanied with technical inconvenience in perfor-ming directed crossing. Application of G3 attracts by the creating conditions for uniting desirable height of plant with the constitutionnal components of Winter Rye productivity.

A Special-purpose Committee on Fungal Names with the Same Epithet was established at the XIX International Botanical Congress (IBC) in Shenzhen, China in 2017, with a mandate to report to the 12th International Mycological Congress (IMC) with recommendations on a preferred course of action with respect to names of pleomorphic fungi sharing the same epithet under the International Code of Nomenclature for algae, fungi, and plants. This report provides a synthesis of the deliberations from the Special-purpose Committee. We discuss the arguments for and against the proposed solution to the problems that have arisen regarding the nomenclature of fungi described in multiple morphs using the same epithet. We also propose a gentler method of addressing the problem using existing procedures.

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.

Мета. На основі багаторічних досліджень за комплексом господарсько-цінних ознак виокремити як вихідний матеріал для селекції за продуктивністю найліпші сорти проса прутоподібного (Panicum virgatum L.). До них належать сорти: ‘Pathfinder’, ‘Carthage’, ‘Blackwell’, ‘Морозко’, ‘Лядовське’ і ‘Зоряне’. Методи. Дослідження проводили протягом 2017–2021 рр. на базі Полтавського державного аграрного університету. Ґрунти дослідної ділянки колекції «Енергетичні культури» – чорноземи типові, з умістом гумусу на рівні 3,4%. Ділянки закладали з рендомізованим розміщенням варіантів в чотирикратній повторності згідно з методиками дослідної справи в агрономії. Також застосовували затверджені науково-практичні й методичні рекомендації до вирощування енергетичних культур. Для підтвердження істотної відмінності між досліджуваними сортами застосовували дисперсійний аналіз з використанням програм Excel та Statistica. Результати. Проведено групування сортів проса прутоподібного за тривалістю вегетаційного періоду на: ранньо- (до 160 діб), середньо- (161–171 доба) та пізньостиглі (понад 170 діб). Установлено комплексну стійкість сортів проса прутоподібного до посухи, морозів та вилягання рослин: ‘Cave-in-Rock’, ‘Зоряне’, ‘Морозко’ та ‘Лядовське’. Визначено, що господарсько-цінні ознаки більшою мірою залежать від сортових особливостей, аніж від умов вирощування. Урожайність наземної вегетативної маси за сухим залишком для досліджуваних сортів варіювала від 12,1 до 15,6 т/га. Висновки. Найпристосованішими до умов вирощування виявилися сорти проса прутоподібного ‘Cave-in-Rock’, ‘Зоряне’, ‘Морозко’ й ‘Лядовське’. Найбільша висота стеблостою відмічена для сортів: ‘Kanlow’ та ‘Cave-in-Rock’, найнижчими виявилися рослини сорту ‘Dacotah’. Значну кількість стебел та високу врожайність біомаси здатні забезпечити сорти проса прутоподібного ‘Pathfinder’, ‘Blackwell’, ‘Shelter’, ‘Carthage’ і ‘Зоряне’. Останні, разом з українським сор­том ‘Зоряне’, рекомендовано використовувати як вихідний матеріал для селекції культури за продуктивністю біомаси.
