Purpose. To study flowering productivity and reproductive ability of multiple-aged plants of introduced Astilba varieties, assess varieties for these characters and investigate the effectiveness of vegetative propagation. Methods. Field experiment, introduction and statistics evaluation. Results. The analysis of published data and author’s own observations revealed that Astilba varieties are highly tolerant for winter and frost conditions as well as pest and disease resistant, therefore we defined flowering productivity and reproductive ability as main economic and biological characters that are subject to assessment. According to the results of flowering efficiency study, it was found that the highest value of this index for the most studied varieties was observed on the fourth year of cultivation. Whereas the majority of varieties rating was relatively low, Astilbe flowering productivity on the whole was sufficiently high. In order to arrange collection plots, flower beds and implement the selection process, the most effective method of vegetative propagation can be used – the division of rhizomes into pieces with three to five renovation buds, and for mass reproduction – with one or two buds. It turned out that for Astilbe the indicator of reproductive ability is specific. For most of the investigated five-year varieties it was quite high. We have noted a high positive correlation between the index of reproductive ability and flowering productivity. Varieties with optimal flowering had high value of planting material yield. Conclusions. Based on the experimental data, the flowering productivity and reproductive ability of multiple- aged plants of Astilbe introduced varieties was studied, varieties was assessed according to these characters, and the effectiveness of vegetative propagation was investigated.

Изучить продуктивность цветения и репродукционную способность разновозрастных растений интродуцированных сортов астильбы, провести оценивание сортов за этими признаками, а также исследовать эффективность вегетативного размножения. Методы. Полевой, интродукционные и статистические. Результаты. На основе анализа литературных данных и по собственным наблюдениям выяснено, что сорта астильбы отличаются высокой зимо- и морозостойкостью и стойкостью к поражению вредителями и болезнями, поэтому основными хозяйственно-биологичес­кими характеристиками, которые подлежат оцениванию, мы определили продуктивность цветения и репродукционную способность. По результатам исследования продуктивности цветения установлено, что наивысшее значение этого показателя у большинства исследуемых сортов наблюдается на четвертый год культивирования. Несмотря на то, что большинство сортов получили довольно низкую оценку, продуктивность цветения астильбы в целом является достаточно высокой. Для создания коллекционных участков, цветников и обеспечения селекционного процесса наиболее эффективным способом вегетативного размножения является деление корневища на части с тремя–пятью почками возобновления, для массового размножения – с одной–двумя почками. Выяснено, что для астильбы показатель репродукционной способности является сортоспецифеским. Для большинства исследуемых сортов в пятилетней культуре он оказалась довольно высоким. Отмечена высокая позитивная корреляция между показателями репродукционной способности и продуктивности цветения. У сортов, которые имели оптимальную продуктивность цветения, наблюдался высокий показатель выхода посадочного материала. Выводы. На основе полученных экспериментальных данных изучены продуктивность цветения и репродукционная способность разновозрастных растений интродуцированных сортов астильбы, проведено оценивание сортов по этим признакам, а также исследована эффективность вегетативного размножения. | Мета. Вивчити продуктивність цвітіння та репродукційну здатність різновікових рослин інтродукованих сортів астильби, провести оцінювання сортів за цими ознаками, а також дослідити ефективність вегетативного розмноження. Методи. Польовий, інтродукційні та статистичні. Результати. На основі аналізу літературних даних та за власними спостереженнями з’ясовано, що сорти астильби відрізняються високою зимо- та морозостійкістю та стійкістю проти ураження шкідниками й хворобами, тому основними господарсько-біологічними характеристиками, які підлягають оцінюванню ми визначили продуктивність цвітіння та репродукційну здатність. За результатами дослідження продуктивності цвітіння встановлено, що найвище значення цього показника у більшості досліджуваних сортів спостерігається на четвертий рік культивування. Незважаючи на те, що більшість сортів отримали досить низьку оцінку, продуктивність цвітіння астильби загалом є доволі високою. Для створення колекційних ділянок, квітників та забезпечення селекційного процесу найефективнішим способом вегетативного розмноження є поділ кореневища на частини з трьома–п’ятьма бруньками поновлення, для масового розмноження – з однією–двома бруньками. З’ясовано, що для астильби показник репродукційної здатності є сортоспецифічним. Для більшості досліджуваних сортів у п’ятирічній культурі він виявився досить високим. Зазначено високу позитивну кореляцію між показниками репродукційної здатності та продуктивності цвітіння. У сортів, з оптимальною продуктивністю цвітіння спостерігався високий показник виходу посадкового матеріалу. Висновки. На основі отриманих експериментальних даних вивчено продуктивність цвітіння та репродукційну здатність різновікових рослин інтродукованих сортів астильби, проведено оцінювання сортів за цими ознаками, а також досліджено ефективність вегетативного розмноження.

Purpose. Determination and analysis of relationship of sowing qualities and yield properties of millet seed (Panicum meliaceum L.) to be formed by the action of predecessors and conditions of mineral nutrition in the context of unstable moistening in the Right-Bank Forest-Steppe zone of Ukraine. Methods. Mathematico-statistical ones (correlation, regression). Results. The use of correlation pleiades method allowed to analyze multifactor relations of sowing qualities and yield properties of millet seed and establish that there was a direct correlation relationship of medium strength (r = 0.52 ± 0.01) between yielding of maternal and millet plants of the first seed progeny. It was found that maternal plants yielding is strongly correlated with laboratory and technological indicators of seed quality that interrelated through integrated quality parameter of seed material (r = 0.56 ± 0.01) and millet output (r = 0.98 ± 0.00). Integrated quality parameter as well as each of the studied laboratory parameters of seed material quality taken separately have a high-level (r = 0.87…0.96 ± 0.00) effect on the formation of grain yield of the first seed progeny plants. Such physical and technological parameters of the quality of maternal plants yield as a content of protein and fat in seed, seed weight, its uniformity can directly, and millet output, thousand-grain weight and hull content – indirectly indicate peculiarities of forming future grain yield of plants of the first seed progeny. Conclusions. The use of the correlation pleiades method allows to analyze objectively the sowing qualities of millet seed and predict the yield properties in the next generation.

Установление и анализ многофакторных взаи­мосвязей посевных качеств и урожайных свойств семян проса посевного (Panicum meliaceum L.), сформированных под действием предшественников и условий неустойчивого увлажнения Правобережной Лесостепи Украины. Методы. Математико-статистический (корреляционный, регрессионный). Результаты. Использование метода корреляционных плеяд позволило проанализировать многофакторные связи посевных качеств и урожайных свойств семян проса посевного и установить, что между урожайностью материнских растений и растений проса первого семенного потомства существует прямая корреляционная связь средней силы (r = 0,52 ± 0,01). Между урожайностью материнских растений и лабораторными и технологическими показателями качества семян существуют сильные корреляционные связи, которые взаимодействуют с ней через интегрированный показатель качества семенного материала (r = 0,56 ± 0,01) и выход пшена (r = 0,98 ± 0,00).

Purpose. To select promising high productive maize hyb­rids of middle-early maturity group in terms of stability and plasticity of main economic characters. Methods. Field study, laboratory test, analytical procedure and statistical evaluation. Results. 14 maize hybrids recorded in the State Register of Plant Varieties Suitable for Dissemination in Ukraine in 2015 were studied for plasticity and stability of such traits as productivity, protein and starch content. Intensive highly-plastic hybrid ‘SI Tiptop’ was selected among the studied ones for productivity trait that can respond properly to changes of growing conditions. It was defined that for the starch content such hybrids as ‘SI Tiptop’, ‘SI Enigma’, ‘SI Arioso’, ‘Svich 38’, ‘Svich 35’, ‘HU 8653’, ‘Zdobutok’ and ‘SI Contrakt’ belonged to the intensive type and combined rather high values and the stability of the studied trait under variable conditions. The following hybrids as ‘NS 2642’, ‘DK S3016’, ‘Svich 38’, ‘NS 2632’ were qualified as intensive for protein content and appeared to be highly-plastic but stability values of this trait were low. ‘Svich 38’ hybrid was intensive simultaneously for two traits such as protein and starch content and showed rather high values of plasticity. ‘SI Tiptop’, ‘SI Enigma’ and ‘Svich 35’ were defined as hybrids of extensive type that provided stable protein content in adverse cultivation conditions. Conclusions. On the condition that intensive crop growing technologies should be used, for obtaining stable yields it is advisable to sow only highly-plastic hybrids that can adapt to unfavorable environmental factors, including ‘SI Tiptop’ – for productivity trait, ‘Zdobutok’ and ‘SI Kontrakt’ – for starch content, ‘MAC 24N‘, ‘NA 2642‘ and ‘Danubio’ – for protein content.

Полевой, лабораторный, аналитический и статистический. Результаты.Исследованы 14 гибридов кукурузы, внесённых в Государственный реестр сортов растений, пригодных для распространения в Украине в 2015 году, по показателям пластичности и стабильности признаков урожайности, содержания белка и крохмала. По признаку урожайности из числа исследуемых гибридов был выделен высокопластичный интенсивный гибрид ‘СИ Типтоп’, который способен соответственно реагировать на изменение условий выращивания. Гибриды ‘СИ Типтоп’, ‘СИ Энигма’, ‘СИ Ариосо’, ‘Свич 38’, ‘Свич 35’, ‘ГУ 8653’, ‘Здобуток’ и ‘СИ Контракт’ по признаку содержания крахмала относятся к гибридам интенсивного типа, которые сочетают достаточно высокие значения исследуемого признака с его стабильностью в изменчивых условиях. К гибридам интенсивного типа по признаку содержания белка отнесены ‘НС 2642’, ‘ДКС 3016’, ‘Свич 38’, ‘НС 2632’ и ‘Данубио’, которые оказались высокопластичными, однако имели низкие значения стабильности этого признака. Интенсивным сразу по двум признакам – содержанию белка и крахмала – является гибрид ‘Свич 38’, который демонстрирует достаточно высокие значения показателей пластичности.

За ознакою урожайності серед досліджуваних гібридів було виділено високопластичний інтенсивний гібрид "СИ Тіптоп", здатний відповідно реагувати на зміну умов вирощування. Гібриди "СИ Тіптоп", "СИ Енігма", "Си Аріосо", "Свіч 38", "Свіч 35", "ГУ 8653", "Здобуток" та "СИ Контракт" за ознакою вмісту крохмалю належать до гібридів інтенсивного типу, які поєднують досить високі значення досіджуваної ознаки з її стабільністю в мінливих умовах. До гібридів інтенсивного типу за ознакою вміста білка віднесено "НС 2642", "ДКС3016", "Свіч 38", "НС 3642" та "Данубіо", які виявилися високопластичними, однак мали низькі значення стабільності цієї ознаки. Інтенсивним відразу за двома ознаками - вмістом білка й крохмалю - є гібрид "Свіч 38", який демонструє досить високі значення показників пластичності. Як гібриди екстенсивного типу, що забезпечують стабільні значення вмісту білка в несприятливих умовах вирощування, визначено "СИ Тіптоп", "Си Енігма" та "Свіч 35". Висновки.

Purpose. Studying variety samples of winter triticale of various ecological and geographical origin for revealing polymorphism of the culture for its susceptibility to pathogenic complex of Fusarium head blight and defining high-yielding and resistant to diseases varieties that later can be put into the production and breeding process. Methods. Field experiments, statistical evaluation. Results. It was defined that the development of Fusarium head blight in different variety samples of winter triticale depends on the hydrothermal conditions and genotype of the host-plant. Resistance of varieties and hybrids to the disease was partial, and no immune samples were found among the analyzed ones. The following varieties proved to be tolerant to Fusarium head blight: ‘Granat’, ‘Zorro’, ‘Obrii Myronivskyi’. The positive correlation between the development of Fusarium head blight and root rot of winter triticale was found. It was determined that in the pathogenic complex of Fusarium head blight the amount of the following pathogens is increasing: Fusarium sporotrichioides, F. аvenaceum and F. poae. Conclusions. The leading varieties that combine high yields and resistance to Fusarium head blight are as follows: ‘Obrii Myronivskyi’, ‘ADM 8’, ‘Yuvileine Volynske’, ‘Yukon’, ‘Zorro’, ‘Tsekad 90’, ‘Zerniatko’, ‘Legion’ and ‘Rarytet’. These varieties should be involved in the selection process to breed the hybrids with the augmented resistance to the disease and high yields.
