Aim. To evaluate the composition and breeding potential of a gene poolcollection of sweet cherry varieties of M.F. SydorenkoMelitopolResearch Station of Fruit Growing of the Institute of Horticulture, NAAS of Ukraine. Result and Discussion.The results of studying the morphological, economic and biological features of sweet cherry (Cerasusavium L. Moench) varieties from the gene pool collection of MelitopolExperimental Station of Horticulturenamed after M.F. Sidorenko of the Institute of Horticulture of NAAS are presented. The history of the collection creation and the genealogy of modern Ukrainian varieties were analyzed. We found that they were the 1st and 2nd generations of traditional Western European varieties. Major sweet cherry varieties that had been most often used in developing modern Ukrainian assortment, were identified. Analysis of the collection showed that 111 accessions of 129 were varieties bred in Melitopol, 40 of which are officially registered.The other accessions are elite forms, which failed the state variety trials or are being tested according to the competitive design. Among the latter, promising forms (candidates for varieties and pre-breeding forms) were distinguished, as they are sources of valuable economic traits. It was determined that the morphogenic process had contributed to the diversity in fruit quality features, which enabled building up a trait collection of sweet cherries for 20 traits with 82 levels of their expression. However, morphogenesis almost did not affect the growth power, fructification nature, generative organs, fructification time and resistance to diseases, therefore there are no significant differences in these features between the collection accessions bred at Melitopol Experimental Station of Horticulture named after M.F. Sidorenko of the Institute of Horticulture of NAAS. Most of the varieties grown on Magalebian cherry plantlet have extensive crowns, bear fruit on "May bouquets" and, after one-year growth, are winter hardy, tolerant to drought, moderately and highly resistant to spur blight and leaf spot as well as self-infertile. On this parent stock, most of the varieties come into fruition after 5-6 years and quickly increase their yields. It was established that enrichment of the gene pool collection with valuable introduced accessions and their wide involvement in hybridization were currently the key objectives aimed at expansion of morphogenesis limits to obtain competitive varieties with high adaptability, productivity and marketability. Conclusions. Modern Ukrainian varieties are the 1st and 2nd generations of traditional Western European varieties. German variety Drogansgelbeknorpelkirsche (DroganaZhyoltaya) with its clone Napoleon Belaya and Russian-Ukrainian variety Valeriy Chkalov were the most actively used in their development. 86% of the gene pool collection of MelitopolExperimental Stationof Horticulture named after M.F. Sidorenkoof the Institute of Horticulture of NAAS are varieties bred in Melitopol differing mainly in ripening time and fruit quality. The collection contains released varieties, a number of sources of valuable traits and, as a tool for the effective implementation of modern breeding programs, requires enrichment with varieties of other eco-geographical groups.

Aim. Based on the results of multi-year research into the flax gene pool, to form a flax training collection to provide breeding scientific organizations and educational institutions with collection samples as well as with information about the bast crop gene pool. Results and Discussion. The studies were conducted in the crop rotation fields for breeding and seed production of the Institute of Bast Crops of the NAAS (Hlukhiv, Sumska Oblast) in 1992-2018. The field measurements and laboratory analyses were carried out in accordance with conventional methods of field and laboratory studies of collection flax samples.The article presents the results on the formation of a training collection of flax at the Institute of Bast Crops of the NAAS, which has 117 accessions (11 botanical species and three varieties) from 22 countries. In addition to species diversity, the collection includes accessions with different levels of expression of valuable economic and biological characteristics. It also includes accessions selected by phenotypic variability of individual characters or their combinations. The multi-year research into the flax collection accessions resulted in identification of sources of highly-expressed valuable economic traits, which are of interest for the plant breeding course. The history of flax breeding in Ukraine is shown, where breeding varieties that are most widespread or were significant breeding achievements in solving certain problems, are presented. The collection can be used as a visual aid for the plant breeding course in educational programs; in addition, it can provide starting material for scientific and educational institutions. The collection is registered with the National Center for Plant Genetic Resources of Ukraine (certificate No. 00273 dated 04/11/2019). Conclusions. The studies of accessions from the national flax collection allowed us to build up a training collection and register it with the NCPGRU. The collection represents a wide range of biological and economic features of the gene pool of this crop. The collection can be used in the educational process of educational agricultural and biological institutions. The multi-year research into the national flax collection resulted in identification of sources of highly-expressed valuable economic traits, which are of interest to the plant breeding course. The history of flax breeding in Ukraine got covered, and breeding varieties that are most widespread or were significant breeding achievements in solving certain problems are presented.

The goal was to include new accessions of perennial leguminous and cereal grasses to the collection, to evaluate them in terms of a set of valuable morphological and economic features and to identify sources of these features for breeding.Results and discussion. The collections of gene pool accessions created due to introduction of cultivars and wild forms as well as breeding accessions identified during practical breeding serve as initial material for the breeding of red clover, alsike clover and cock's-foot in the Institute of Agriculture of the Carpathian Region. For the period of 2000-2017, 944 accessions of forage grasses registered in the Central Database were included in the collection: 405 legumes (red clover – 161, alsike clover – 11) and 539 cereals (cock's-foot – 145); 591 accessions were stored in the National Depository. In-depth studies of morphological and economic traits of the accessions allowed us to create and to register a basic collection of the forage grasses gene pool, a trait collection of red clover for yield and resistance to powdery mildew (it includes 52 accessions from 5 countries), a trait collection of cock's-foot for yield and resistance to unfavorable factors (49 accessions from 8 countries) and to register valuable red clover accession No. 193 and cock's-foot accession Drogobychanka Piznia with the NCPGRU. Based on the collection accessions, varieties were created and included in the State Register of Plant Varieties Suitable for Dissemination in Ukraine: red clover Truskavchanka since 2016, alsike clover Prydnistrovska since 2002, cock's-foot Marichka since 2014. Since 2015, red clover variety Ukrainochka and cock's-foot variety Boikivchanka have been tested in the state scientific expert evaluation.Conclusions. The creation of the genetic resource collection allowed us to study and analyze the genetic potential of the species, to identify initial material with valuable economical traits, which will significantly increase the efficiency of fodder grasses breeding.

Abstract. Title of the paper: Level estimation of metabolic parameters in the glucose tolerance test (GTT) of young bulls The metabolic parameters of the glucose tolerance test are suitable for an additional recommendation for the valuation of the breeding bulls before the start of the offspring’s test could be given. Very important is the level of glucose half live to the begin of lactation of the cows. The other limit is the hyperglycemias greater than 10 mmol/l (or 180 mg/dl) in the glucose level in the blood. The glucose half live measured nearly 48 minutes is comparable in the 8th week post partum in lactation of cows with the young bulls in the age one year. Their combination with the pedigree breeding value is leading to increase of information, that could be utilised to the selection of improper bulls if the present results were confirmed.

Ukrainian population of red dairy cattle is genetically active, its gene pool is significantly improved in each of the next generations, mainly due to artificial selection. Currently breeding structure of Ukrainian Red Dairy breed has the prospect of future expansion due to creating Podolian zonal type. Features of its formation are to use as the original breed, which being improved, Red Polish cattle. This breed, as Red Steppe cattle, was listed as a breed to preserve the gene pool under pure breeding. However, gene pool preservation of these breeds is impossible through lack of sufficient number of purebred bulls or their semen at breeding enterprises in Ukraine. The aim of our research was to study genesis and development prospects of red dairy cattle in Ukraine. Materials and methods of research. The materials of the research were the data of identifying breed composition of cattle in Ukraine by January 1, 2015, State Breeding List for 2005, 2010 and 2015, the electronic information database of leading breeding farms for 2007 and 2011 and database of bulls admitted to using during 2005, 2010 and 2015 of Institute of Animal Breeding and Genetics named after M.V. Zubets of NAAS. Results. Currently the group of cows of red breeds is about 365 thousand head, including 97.9 thousand head concentrated in agricultural enterprises. The largest share of this group takes the Red Steppe cattle (84.5%), the smallest one –Ayrshire and Angler breeds (0.7-0.8%). In Ukraine, the total number of Ukrainian Red Dairy cattle is about 40 thousand head, including 21.4 thousand head of cattle concentrated in agricultural enterprises. The results of these annual reports have shown that the average milk yield of the group of cows of red breeds was 3328 kg of milk in 2001. Then milk yield increased with each subsequent studied period and reached the highest figure of 4681 kg in 2014. So, increasing milk yield of cows was by 1353 kg of milk or 29% during fourteen years (2001-2014). The number of breeding animals of Red Steppe, Red Polish, Ayrshire, and Ukrainian Red Dairy breeds significantly decreased in the controlled part of population during the past fourteen years. However, level of milk production and quality increased slightly, except for Red Polish breed. Thus, 4688 cows of Ukrainian Red Dairy breed had milk yield in 5981 kg and milk fat content in 3.88% according to the appraisal of 2014, whereas, in 2013, 4902 cows had milk yield in 5837 kg with milk fat content in 3.86%. Up to 90% of the realized genetic progress in large-scale breeding is provided by using proven bulls, resulting most current need is to restore the national system of selection and testing of sires. The results show that during the past ten years, the number of proven bulls, admitted to using within the red breeds decreased almost seven times with a simultaneous increase 2.2 times in breeding value. Among 410 proven bulls, admitted to using in 2005 (bulls which being tested by progeny), unreasonably disproportionate share was for Holstein sires – 245 (59.8%), whereas, the share of bulls of the red breeds – 13.7%. In 2010, 123 bulls (65.4%) were of Holstein breed and only 9 ones (4.8%) – of Ukrainian Red Dairy among 188 bulls, admitted to using. In 2014, a similar situation was observed; there were 93 bulls, admitted to using, including 48 ones (51.6%) of Holstein and only 3 ones (3.2%) of Ukrainian Red Dairy breed. Given the current state of livestock breeding base on all the red breeds (Red Steppe, Ukrainian Red Dairy, Angler, Red Polish) we developed possible options of parameters of large-scale breeding. During the planning period the number of the controlled cows of the red breeds (mainly Ukrainian Red Dairy cattle) should be significantly increased. Calculations show that in the first stage of the program available number of cows in breeding farms, even if 30% of cows allocated to mating with laid-off bulls, is less than a third of the minimum at pressure of selection among laid-off bulls 1: 4 by productivity of 50 daughters. At the end of the program it is planned to increase the pressure of selection among laid-off bulls to 1:5 under increase of the controlled livestock number to 43700 cows (nearly 4.4 times against currently available one) Conclusion. Our results showed that, the number of breeding farms, in which were bred red cattle, significantly declined and the livestock number also decreased whereas milk production increased during 2001-2015. The high level of genetic potential of Ukrainian Red Dairy cows indicates the presence of highest-yielding cows with yield more than 10 000 kg of milk. At the same time, such animals at breeding farms for breeding Red Polish, Steppe, Ayrshire and Angler cattle weren’t found. During the past ten years, the number of proven bulls of red breeds, admitted to using, decreased almost seven times with a simultaneous increase of breeding value in 2.2 times. Predominance of Holstein bulls remains indisputable on reliability of assessment of breeding value. It causes the biggest request and the widest offer on the market of semen from bulls of the breed. The actual destruction of domestic system of sires breeding caused significantly lower rate of repeatability of breeding values in bulls of the red breeds. This is a concern and threatens possible loss or significant restriction of the gene pool of red breeds.

Abscisic acid (ABA) plays a major role in promoting ripening in sweet cherry, a non-climacteric fruit. Exogenous application of ABA has been performed to study fruit ripening and cracking, but this growth regulator is not used for commercial production. To determine the potential of this growth regulator to improve sweet cherry fruit quality, ABA canopy spraying was assayed in four cultivars. Canopy spraying of S-ABA significantly: (1) enhanced sweet cherry fruit color in ‘Glenred’, ‘Lapins’ and ‘Bing’ cultivars, but not in ‘Royal Rainier’ (a bi-colored cultivar), and (2) decreased fruit size and firmness in ‘Lapins’, ‘Bing’ and ‘Royal Rainier’. Seasonally reproducible effects were seen in ‘Lapins’ (mid/late-maturing) but not in ‘Glenred’ (early-maturing). Canopy spraying of nordihydroguaiaretic acid (NDGA) decreased color and increased fruit size in ‘Lapins’, but not in ‘Glenred’. Direct application of ABA on fruits attached to the tree, without application to the foliage, increased ‘Lapins’ fruit color without reducing size. These results suggest a localized fruit response to exogenous ABA application on fruit color development, but that a decrease in fruit size may be due to the effects of exogenous ABA on the tree canopy foliage.
