Мета. Встановити сортові особливості формування продуктивності гречки (Fagopyrum esculentum Moench) в умовах нестійкого зволоження Центрального Лісостепу залежно від строків та способів сівби. Методи. Упродовж 2015–2017 рр. в умовах Устимівської дослідної станції рослинництва Інституту рослинництва імені В. Я. Юр’єва НААН досліджували 6 сортів гречки: ‘Ярославна’, ‘Слобожанка’, ‘Руслана’, ‘Українка’, ‘Крупинка’, ‘СИН-3/02’. Висівали гречку нормою 250 зерен/м2 широкорядним (міжряддя – 45 см) та звичайним рядковим (15 см) способом у три строки з інтервалом у 5 діб: 5–6 травня (температура ґрунту 14,5–16,6 °С), 10–11 та 15–16 травня (16,4–19,1 та 16,9–17,3 °С відповідно).Результати. Результати трирічного експерименту засвідчують істотний вплив досліджуваних факторів (сорту, строку і способу сівби) на формування елементів продуктивності гречки, що змінювалися в досить широкому діапазоні (кількість зерен з однієї рослини – від 2,8 до 17,4 шт., маса 1000 зерен – до 2,4 г, урожайність – від 0,1 до 1,2 т/га) і значною мірою залежали від погодних умов весняного періоду. Посушливі умови на початку вегетації знижували крупність зерна та озерненість рослин, що зумовлювало зменшення врожайності, тоді як більш вологі умови навпаки збільшували ці показники. Водночас, сорти ‘СИН-3/02’ і ‘Крупинка’ в посушливих умовах 2017 року відреагували збільшеням врожайності в разі сівби звичайним рядковим способом. Якщо в попередні роки вони забезпечували вищу врожайність за широкорядного висіву, то в несприятливих для росту й розвитку рослин умовах, доцільнішим виявився звичайний рядковий спосіб, а строк сівби істотного впливу на цей показник не мав. Строками сівби гречки (з різницею в 5 діб) не завжди можна нівелювати негативний вплив погодних умов. Спосіб сівби є дієвим фактором впливу на формування високих показників структурних елементів продуктивності та потенціалу врожайності зерна гречки, що певною мірою обумовлено біологічними особливостями сорту.Висновки. Серед досліджуваних сортів гречки найбільшою врожайністю відзначався сорт ‘Ярославна’ за сівби широкорядним способом у першій декаді травня (5–6.05). Ці елементи технології вирощування були кращими і для сортів ‘Слобожанка’ і ‘Руслана’. Другий строк сівби (10–11 травня) є сприятливішим для сортів ‘СИН-3/02’ та ‘Українка’ за широкорядного способу сівби. Гречка ‘Крупинка’ забезпечувала найбільшу продуктивність за сівби в першій-другій декаді травня широкорядним способом. У разі сівби в третій строк (15–16.05) усі сорти формували зменшені показники елементів продуктивності порівняно з іншими строками і способами сівби. | Purpose. To study the varietal peculiarities of the buckwheat (Fagopyrum esculentum Moench) productivity formation in the conditions of unstable hydration of the Central Forest-Steppe zone of Ukraine, depending on the timing and methods of sowing.Methods. During 2015–2017, at the Ustymivka Experimental Station of Plant Production (Yuriev Plant Production Institute, NAAS of Ukraine) 6 varieties of buckwheat: ‘Yaroslavna’, ‘Slobozhanka’, ‘Ruslana’, ‘Ukrainka’, ‘Krupynka’, ‘SIN 3/02’ were studied. Buckwheat was sowed at a rate of 250 grains/m2 by wide (row spacing – 45 cm) and usual row (15 cm) methods into 3 steps with 5 days intervals: 5–6 May (soil temperature 14.5–16.6 °C), 10–11 and 15–16 May (16.4–19.1 and 16.9–17.3 °C correspondently).Results. The results of the three-year experiment indicate a significant impact of the factors (variety, timing and method of sowing) on the buckwheat productivity formation, which varied in a rather wide range: the number of grains on one plant varied from 2.8 to 17.4 pcs.; the weight of 1000 grains – up to 2.4 g; yield – from 0.1 to 1.2 t/ha; and in higher degree depended on the weather conditions in the spring period. The arid conditions at the beginning of the vegetation phase reduced the grain size and number on the plants that caused a decrease in yield, while more humid conditions increased these rates. At the same time, the varie­ties ‘SIN-3/02’ and ‘Krupynka’ in the dry conditions of 2017 showed increased yields in the case of sowing in the usual routine manner. In previous years they provided higher yields for wide-row sowing, while in unfavorable conditions for growth and development, the usual routine method was more suitable, and the term of sowing did not have a significant impact on this. The terms of sowing with the intervals in 5 days, can not mitigate the negative effects of weather conditions, in general. The method of sowing is an effective factor for high buckwheat productivity and yield formation that to a certain degree depends on biological characteristics of the variety. Conclusions. Among the studied buckwheat varieties, the ‘Yaroslavna’ variety characterized by the highest yield in case of wide-row sowing in the first decade of May (5–6.05). These elements of cultivation technology were better for the varieties ‘Slobozhanka’ and ‘Ruslana’. The second term of sowing (May 10–11) is more favorable for the varieties ‘SIN-3/02’ and ‘Ukrainka’ with the wide-row sowing. Buckwheat ‘Krupynka’ provided the highest yield with wide-row sowing in the first or second decade of May. In the case of sowing in the third term (15–16.05) all the varieties characterized by reduced productivity in comparison with other terms and methods of sowing | Цель. Установить сортовые особенности формирования продуктивности гречихи (Fagopyrum esculentum Moench) в условиях неустойчивого увлажнения Центральной Лесостепи Украины в зависимости от сроков и способов сева. Методы. В течение 2015–2017 гг. в условиях Устимовской опытной станции растениеводства Института растениеводства имени В. Я. Юрьева НААН исследовали 6 сортов гречихи: ‘Ярославна’, ‘Слобожанка’, ‘Руслана’, ‘Українка’, ‘Крупинка’, ‘СИН-3/02’. Высевали гречиху нормой 250 зерен/м2 широкорядным (междурядья – 45 см) и обычным строчным (15 см) способом в три срока с интервалом в 5 суток: 5–6 мая (температура почвы 14,5–16,6 °С), 10–11 и 15–16 мая (16,4–19,1 и 16,9–17,3 °С соответственно). Результаты. Результаты трехлетнего эксперимента свидетельствуют о существенном влиянии исследуемых факторов (сорта, срока и способа сева) на формирование элементов продуктивности гречихи, что изменялись в достаточно широком диапазоне (количество зерен с одного растения – от 2,8 до 17,4 шт., масса 1000 зерен – до 2,4 г, урожайность – от 0,1 до 1,2 т/га) и в значительной степени зависели от погодных условий весеннего периода. Засушливые условия в начале вегетации снижали крупность зерна и озерненность растений, что приводило к уменьшению урожайности, тогда как более влажные условия наоборот увеличивали эти показатели. В то же время, сорта ‘СИН-3/02’ и ‘Крупинка’ в засушливых условиях 2017 года отреагировали увеличением урожайности в случае сева обычным строчным способом. Если в предыдущие годы они обеспечивали высокую урожайность при широкорядном посеве, то в неблагоприятных для роста и развития растений условиях более целесообразным оказался обычный строчный способ, а срок сева существенного влияния на этот показатель не имел. Сроками сева гречихи (с разницей в 5 дней) не всегда можно нивелировать негативное влияние погодных условий. Способ сева является действенным фактором влияния на формирование высоких показателей структурных элементов продуктивности и потенциала урожайности зерна гречихи, что в определенной степени обусловлено биологическими особенностями сорта. Выводы. Среди изучаемых сортов гречихи наибольшей урожайностью отличался сорт ‘Ярославна’ при посеве широкорядным способом в первой декаде мая (5–6.05). Эти элементы технологии выращивания были лучшими также для сортов ‘Слобожанка’ и ‘Руслана’. Второй срок сева (10–11 мая) является благоприятным для сортов ‘СИН-3/02’ и ‘Українка’ при широкорядном способе посева. Гречиха ‘Крупинка’ обеспечивала наибольшую продуктивность при посеве в первой-второй декаде мая широкорядным способом. В случае сева в третий срок (15–16.05) все сорта формировали уменьшенные показатели элементов продуктивности по сравнению с другими сроками и способами посева.

Purpose. The analysis of allelic status of such key genes of carotenogenesis as gene of lycopene-ε-cyclase (lcyε) and gene of β-carotene hydroxylase (crtRB1) for DNA-markers in domestic maize lines and their hybrids. Methods. DNA isolation, PCR, gel electrophoresis. Results. Allelic status of key genes of carotenogenesis was investigated in eight maize inbred lines and their single crosses. Molecular genetic polymorphism in the studied sample of maize lines and hyb­rids has been detected in gene of β-carotene hydroxylase for marker crtRB1-3’TE. For this gene, codominant character of inheritance of alleles of parental lines in single crosses was confirmed. For markers of gene of lycopene-ε-cyclase lcyε-3’INDL and lcyε-SNP216, polymorphism in the group of investigated lines and hybrids has not been identified, genotypes included only one variant of alleles for each marker. For lines ‘DK253ZSZM’, ‘DK633/266zS,zM’, ‘DK366zS,zM’ and hybrids ‘DK296S×DK253ZSZM’, ‘DK272S×DK633/266zS,zM’ and ‘DK231S×DK366zS,zM’, the decrease of the activi­ty of β-carotene hydroxylase owing to the mutation of gene crtRB1 under the influence of transposone element at the 3’-end, the inhibition of β-carotene transition into β-cryptoxanthin can be expected, that allows to predict β-carotene accumulation in grain. Conclusions. The study of allelic status of carotenegenesis gene of lycopene-ε-cyclase in maize showed no polymorphism for markers lcyε-3’INDL and lcyε-SNP216 in eight inbred lines and their single crosses, along with this, for marker lcyε-3’INDL in genomes of all studied samples the allele was identified to be favorable for the accumulation of β-carotene. For marker crtRB1-3’TE of gene of β-carotene hydroxylase, the studied breeding material was polymorphic. Allele of crtRB1 being favorable for the accumulation of β-carotene was identified in lines ‘DK253ZSZM’, ‘DK633/266zS,zM’, ‘DK366zS,zM’ and hybrids ‘DK296S×DK253ZSZM’, ‘DK272S×DK633/266zS,zM’ and ‘DK231S×DK366zS,zM’. Single crosses inherit maternal and paternal alleles of gene of β-carotene hydroxylase codominantly.

Purpose. To analyse the Ukrainian nomenclature of subtribe Malinae representatives and improve terminological system of the Ukrainian names of a species and a generic levels and names of fruit crops. Results. There is a confusion in the Ukrainian names of plants of Cydonia-Chaenomeles–Pseudocydonia, Mespilus–Eriobotrya, Amelanchier–Cotoneaster. Considering the division of Sorbus s.l. on separate genera Sorbus s.str., Aria, Cormus, Chamaemespilus, Torminalis and availability of numerous hybrids with their involvement, the Ukrainian names for both taxa and nothotaxa of species and generic levels are offered, principles of their choice are also considered. Formation of the Ukrainian generic names on the basis of specific epithets leads to undesirable tautonomy. Aspects of derussification of the Ukrainian professional terminology are discussed. Conclusions. Ukrainian scientific generic and nothogeneric plant names for subtribe Malinae are transliterated/transcripted, borrowed as a calque of latin names or have their own origin, consisting of one or two words. The choice of the best variants of generic and species names from a number of possible ones has a temporal component and largely depends on experts who apply them and basic principles of choice. It is necessary to improve the modern Ukrainian plant nomenclature on a national basis involving the transformed Latin scientific names for introduced species and hybrids.

Purpose. Studying the inheritance of such trait of soybean (Glucine max (L.) Merrill) as growing season length in F2 and assessing hybrid combinations to identify more quick-ripening phenotypes as compared to parents. Methods. Laboratory test, mathematico-statistical evaluation. Results. In most crossbreeding combinations, when parents differed by growing season length, late ripeness was dominated in F2, in one combination – early ripeness, in two combinations, when parents scarcely differed by growing season length, complementary effect was observed for this index. It was found that ‘Anzhelika’/‘Mageva’ combination generated the highest number of more quick-ripening forms than any of the parents (13.1%), a smaller number was identified in ‘Legenda’/‘Vizhion’ (6.4%) and ‘Anzhelika’/‘Gentleman’ (4.0%), and barely noticeable number was observed in ‘Legenda’/‘Yelena’ combination (1.3%). Conclusions. In the following crossbreeding combinations as ‘Legenda’/‘Vizhion’, Legenda’/‘Korado’, ‘Legenda’/‘Ustia’, ‘Legenda’/‘Yelena’, ‘Yug-30’/‘Gentleman’, ‘No. 894’/‘Vizhion’, ‘Anzhelika’/‘Annushka’, ‘No. 894’/‘Annushka’, ‘Legenda’/‘Annushka’, ‘No. 441’/‘Gentleman’, ‘No. 441’/‘Vizhion’, ‘No. 441’/‘Annushka’, ‘Anzheli­ka’/‘Gentleman’ and ‘Anzhelika’/‘Prypiat’ when parents considerably and insignificantly differ by growing season length, late ripeness was dominated in F2. ‘Ustia’/‘Vizhion’ and ‘Yug-30’/‘ Vizhion’ crossbreeding combinations in which parents hardly differ by growing season, complementary effect was observed in F2 for this index.

Purpose. Theoretical and experimental substantiation of introduction of “Romantica” roses originated by Meilland company under the conditions of the Right-Bank Forest-Steppe Zone of Ukraine. Methods. Biometrical, comparative-morphological, statistic ones. Results. Viability, growth and development indices as well as ornamental qualities (tolerance for winter conditions, frost hardiness, drought resistance, complex disease and pest resistance, habit maintenance, shoot formation, flowering, coloration, shape of flowers, petal number etc.) were analyzed for 12 rose cultivars of “Romantica” series planted on the collection and exhibition plots of the National Dendrological Park «Sofiivka» NAS of Ukraine. The investigations were conducted within 2012–2015. The most of the cultivars got the mark of introduction success 41–45 points of 50; so, the cultivars are totally promising for introduction into the conditions of the Right-Bank Forest-Steppe Zone of Ukraine. ‘Leonardo da Vinci’ and ‘Yves Piaget’ cultivars got point number 35–38 and they can be considered promising ones. The acclimatization number for the most of the investigated cultivars was 85–90 points of 100 that means good adaptation of the plants in the conditions of the Right-Bank Forest-Steppe Zone of Ukraine. The adaptation of cv. ‘Leonardo da Vinci’ and cv. ‘Yves Piaget’ roses (point number 75) can be considered satisfactory. The total evaluation of “Romantica” roses ornamental qualities made 76–87 points of 100; so, all the cultivars display high ornamental qualities and deserve to be introduced to the production. Conclusions. The garden roses of “Romantica” series originated by Meilland company being introduced into the conditions of the Right-Bank Forest-Steppe Zone of Ukraine are adapted well in the introduction region and they are promising for the subsequent introduction.

Purpose. Analysis of hexaploid triticale breeding process for drought resistance through the use of systemic ecological tests in contrasting conditions. Methods. Dialectical, field, laboratory and statistical ones. Results. Medium-grown (‘Amos’, ‘Nikanor’, ‘Rarytet’, ‘Yaroslava’) and low-stem (‘HAD 69’, ‘HAD 86’, ‘HAD 110’, ‘Timofei’) multiline varieties of winter and alternate hexaploid triticale were developed with higher adaptability, potential yield of 9–12 tons per ha and high bread-making properties. Among the most drought resistant genotypes, such varieties as ‘Amos’, ‘Buket’, ‘Harne’, ‘Markiian’, ‘Kharroza’, ‘Shalanda’, ‘Nicanor’ and ‘Yaroslava’ showed high values of yield, plasticity and stability. Conclusions. The use of interspecific hybridization instead of intergeneric one in hexaploid triticale breeding, together with systemic testing of the hybrid material in contrasting agro-ecological zones, ensured the creation of multiline competitive varieties with an optimal combination of yield and adaptive properties

Purpose. To analyze peculiarities of Ukrainian cereals and oilseeds trade, the situation on the world market, and determine future prospects of its development. Methods. Analysis and synthesis, comparative evaluation, graphic procedure. Results. The role and place of Ukraine in a total grain supply to the world market was determined. Ukraine is a world’s top ten grain producer. Among domestic agricultural products, cereals, oilseeds and sunflower oil are in the highest demand in the world. In recent years, our state has reinforced its status as one of the leading exporters of cereals. The commodity pattern of cereals and oilseeds export was analyzed with specifying most in-demand positions and the main countries purchasing these pro­ducts. According to the results of 2015, Ukraine obtained the highest foreign currency revenue from export of corn, wheat and barley (in grain structure) including soybeans and rapeseed (among oil crops). Key domestic and multinational operators are the main exporters of cereals and oilseeds in Ukraine and still hold their leading position. It was found a significant excess of import price of seeds as compared with export price of crops grown in Ukraine. Assortment of maize and sunflower seeds offered by major companies-producers in Ukraine was studied. Main trends of the world grain market development are considered. Conclusions. It was established that Ukraine is one of the major exporters of cereals and oilseeds. However, volatility of their prices significantly affects the export revenue that was decreasing even with increasing export quantities in kind. The dependence of domestic grain industry development on high-quality imported seed of maize and sunflower hybrids was recorded. It is expected that in the years to come Ukraine will maintain its strong positions in the world’s grain market.

Analysis and synthesis, comparative evaluation, graphic procedure. Results. The role and place of Ukraine in a total grain supply to the world market was determined. Ukraine is a world’s top ten grain producer. Among domestic agricultural products, cereals, oilseeds and sunflower oil are in the highest demand in the world. In recent years, our state has reinforced its status as one of the leading exporters of cereals. The commodity pattern of cereals and oilseeds export was analyzed with specifying most in-demand positions and the main countries purchasing these pro­ducts. According to the results of 2015, Ukraine obtained the highest foreign currency revenue from export of corn, wheat and barley (in grain structure) including soybeans and rapeseed (among oil crops). Key domestic and multinational operators are the main exporters of cereals and oilseeds in Ukraine and still hold their leading position. It was found a significant excess of import price of seeds as compared with export price of crops grown in Ukraine. Assortment of maize and sunflower seeds offered by major companies-producers in Ukraine was studied. Main trends of the world grain market development are considered. Conclusions. It was established that Ukraine is one of the major exporters of cereals and oilseeds. However, volatility of their prices significantly affects the export revenue that was decreasing even with increasing export quantities in kind. The dependence of domestic grain industry development on high-quality imported seed of maize and sunflower hybrids was recorded. It is expected that in the years to come Ukraine will maintain its strong positions in the world’s grain market.
