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.

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.

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.

A technology of spring barley growing was described in the article, especially of its new varieties, provision of the brewing industry with high- quality malt through the diversification of planting areas and volumes of growing was explained, and establishment of the brewer’s barley market was described as well. Economical efficacy of the brewer’s and ordinary barley was calculated in order to provide a comparison.

Created in Nikitskyi botanical garden Remote hybrids of nectarine and peach with almond ordinary can be used in Breeding of nectarine and peach fok high resistauce to fundi, as wengs for creation of varieties of nectarine with high drought resistance, sweet seed kernels, high contents of organic substance, and other important Breeding characteristics. Late blossoming hybrid forms can be used in Breeding of almond fok late time of flowering and selfcompatibility.
