Assessment of agroclimatic conditions in 2012–2014 and their effect on formation of frost resistance and winter hardiness of soft winter wheat is made. Elevated temperature conditions in autumn and disturbance of cold hardening conditions caused the formation of the highest frost tolerance and winter hardiness of winter wheat only up to -15°C. Under the new climatic conditions the modern varieties of myronivska breeding are able to realize 80–85% of the genetic potential by the property.

Yield of modern varieties of valuable fodder crop lucerne is quite low - 0.2 - 0.3 t / ha. The reason - lack of cross-pollination due to the lack of insect pollinators. Under these conditions, the highest seed production plants are prone to selfpollinate. The results of the study of 26 new selffertile samples of alfalfa own selection. It was shown that 15 samples for seed yield higher than standard - grade Jaroslavna. The herbage yield of only four samples was lower than in the standard. The dry matter content of all samples was high - 22,1-25,5 %. The results obtained are allowed to select in hotbed of pre-strain testing samples with high levels of self-fertility, seed yield 0,24-0,29 t/ha, herbage for three mowing - 63,2-67,7 t/ha, high dry matters content, which will be used in future breeding process

Zoological collections are the main repositories of biodiversity for specific regions or taxa. However, they often lack promotion and consequently remain largely unknown to the general public or even for specialists. Moreover, many of these collections are at risk of deterioration and, in many cases, lack taxonomic review. Founded in 1771, the Museo Nacional de Ciencias Naturales (MNCN; Madrid, Spain) is one of the oldest Natural History Museums in the world and one of the most important scientific research institutions in the field of Natural Sciences in Europe. The review conducted in this study resulted in an annotated catalogue of marine Heterotremata crabs, documenting 83 species across 21 families from the MNCN collection. It was found that only 21.9% of the specimens had been correctly identified, while 78.1% were either unidentified, identified only to the family level, or misidentified. This highlights a significant loss of biodiversity information and missed opportunities for identifying new species, as many specimens had been inadequately identified for up to 175 years. The review also expanded the known geographic distribution of several species, with the first-time recordings in regions such as Mauritian, Equatorial Guinean, Moroccan, Ghanaian, and São Tomé and Príncipe waters. The study emphasizes the importance of access to zoological collections and collaboration with specialists to enhance our understanding of biodiversity.

The effect of sowing time on realization of the natural productivity potential of modern soft winter wheat varieties was studied. It is established that the use of current agricultural technologies in a context of climate change has caused shift of calendar sowing terms to the second half of the optimal terms comparing with earlier cultivated varieties. In subzones of Kirovohrad and Bila Tserkva state variety testing stations the highest yield of winter wheat is formed in case of sowing on September 20–30, but the optimum for Kirovohrad station fall on September 30, Bila Tserkva station – on September 20 and 30. Sowing in earlier or later time leads to decreasing yields, especially of Vynnychanka, Smuhlyanka, Zolotokolosa and Tripilska varieties. Bogdana and Kuialnyk varieties are the most adaptive to sowing time under agroecological conditions of Kirovohrad state variety testing station.

The results obtained during the study of resistance of promising gooseberry varieties to Septoria leaf spot in the Western Forest-Steppe of Ukraine are described. Variety samples were divided into groups by the resistance to disease. Among them none was found with complete field resistance. Sladkiy proved to be highly resistant variety. Resistance above the average is typical for Berill, Grushenka, Kooperator, Lehin, Malakhit, Rodnik, Shennon varieties. Hrossulyar, Kamenyar, Karat, Knyazhych, Kolobok, Krasnoslavyanskiy, Laskovyi, Mazershkota, Russkiy, Svityaz, Severnyi kapitan are varieties of average resistance to Septoria leaf spot. Zyelyonyi dozhd, Zlatogor, Invikta, Kubanyets, Nesluhivskyi, Slivovyi are characterized as low resistant ones.

The kernel size of winter rye is a genetically determined characteristic as controlled by a series of multiple alleles and is available for artificial selection. As a result of long-term intensive selection average weight of 100 grains per plant increased from 2.94 to 6.94 g or 2.4 times. The implemented effectiveness of selection by 100 grains weight per plant towards increase was systemic, but it was also uneven. Throughout 42 generations the spans of quick response to directed selection were observed, lasting slowdowns and even reverses of average weight of 100 grains per plant. Prompt increase of the directed selection efficiency corresponded to the changes that induced relatively big impact, and formed a plateau as large kernel size reached high frequency. Variability of rye population at high pressure of the selection by 100 grains weight pert plant occurred predominately at normal distribution and along the display of negative asymmetry following the effect of extreme grades emergence outbreak. The highest average kernel size achieved was followed by further slowdown of 100 grains increase observed, nonetheless a heavy pressure of the selection. 42 generations displayed the greatest impact upon the breeding efficiency by denominated breeding differential (36%), selection intensity (22%), broad sense inheritance ratio (8%), narrow sense inheritance ratio (10%). Predicted and implemented selection efficiency over 42 generations matched in 37% of cases certifying thus an actual forecast of the breeding prediction.

Elements of energy-saving technology of table beet seed production (variety type of Bordeau) in the Eastern Forest-Steppe of Ukraine were improved, they include method of irrigation (drip irrigation, HB 70–65%), fertilizing (locally N 15 P 30 K 60 + N 15), fertigation (stage of 3–4 true leaves, bundle ripeness, the beginning of stooling and flowering), the use of standard mother roots 61–100 mm in diameter along with mother rootsstecklings 41–60 mm in diameter that increase average yields according to the size up to 1,89 t/ha. It is found that the application of micronutrient mixture of Zn + B + Mo in one term and mixture of Zn + B in two terms was the most effective.
