Purpose. To evaluate the productivity and grain quality of winter triticale varieties grown under different soil and climatic conditions. Methods. The research process involved laboratory, computational and statistical methods, and analysis and synthesis to draw conclusions. Results. HTC (IV–X) was found to vary significantly monthly, annually and in general between the research sites. It was found that the yield of winter triticale varieties in the Forest-Steppe and Polissia zones was 5.3 t/ha. The maximum yield in the Forest-Steppe zone was achieved by the variety ‘MIP Feniks’ (5.9 t/ha), in the Polissia zone by the variety ‘Pamiati Patseky’ (5.8 t/ha). It was found that the protein content of winter triticale varieties for the 2019–2020 research years in the Forest-Steppe zone was on average 12.6% and ranged from 12.2% (‘Liubomyr’) to 13.3% (‘MIP Yatahan’), which according to the classifier corresponded to grain of medium quality and can be used in the confectionery industry. The coefficient of variation (V,%) for this characteristic was 3.5%. In the Polissia zone, the protein content of the varieties averaged 13.6% over the years of research and ranged from 12.9% – medium content (‘MIP Feniks’) to 14.3% – high content (‘MIP Yatahan’). The intrazone variation was low and amounted to 4.0%. Correlation and regression analysis showed that an increase in the active temperature during the vegetation period up to 3203 оС allows an increase in the productivity indicators and in the weight of 1000 grains from 5.6 to 6.1 t/ha and from 46.8 to 53.5 g, respectively; an increase in precipitation during the vegetation period up to 515.1 mm leads to a decrease in the weight of 1000 grains from 45.2 to 38.1 g; with an increase in the amount of active temperatures and precipitation during the vegetation period from 3167.65 to 3202.9 оС and from 413.85 to 515.1 mm, respectively, it is possible to increase the protein content in grain from 12.4 to 13.8%; with an increase in the yield and weight of 1000 grains from 5.8 to 6.1 t/ha and from 51.8 to 53.8 g, the protein content of the grain can be reduced from 13.1 to 12.0%. Conclusions. Different responses of varieties to zonal growing conditions were observed. A positive influence of the rainfall factor during the growing season on the yield of winter triticale in Forest-Steppe and Polissia (r = 0.66 and 0.34 units) and on the increase of the protein content of grain grown in the Polissia zone (r = 0.56) was revealed.

Оцінити продуктивність та якість зерна сортів тритикале озимого, вирощуваного в різних ґрунтово-кліматичних умовах. Методи. У процесі досліджень використовували лабораторний, розрахунковий і статистичний методи, для підготовки висновків – аналізу та синтезу. Результати. Виявлено суттєву зміну ГТК (IV–X) щомісячно, щорічно і загалом по локаціях проведення досліджень. Визначено, що врожайність сортів тритикале озимого в зонах Лісостепу й Полісся становила 5,3 т/га. Максимальні її показники в лісостеповій зоні отримано для сорту ‘МІП Фенікс’ (5,9 т/га), у поліській – для ‘Пам’яті Пацеки’ (5,8 т/га). Середній уміст білка в зерні досліджуваних рослин за 2019–2020 рр. у Лісостепу становив 12,6% (від 12,2% у сорту ‘Любомир’ до 13,3% у ‘МІП Ятаган’), що, за класифікатором, відповідає зерну середньої якості, придатному для використання в кондитерській промисловості. Коефіцієнт варіації (V,%) за цією ознакою – 3,5%. Усереднена кількість білка для вирощуваних на Поліссі сортів тритикале озимого – 13,6% (від 12,9% у ‘МІП Фенікс’ до 14,3% (високий уміст) у ‘МІП Ятаган’). Варіація в межах зони становила 4,0% – слабка. Кореляційно-регресійним аналізом встановлено, що збільшення суми активних температур до 3203 °С у період вегетації може спричинити підвищення показників урожайності та маси 1000 зерен із 5,6 до 6,1 т/га та з 46,8 до 53,5 г відповідно; збільшення суми опадів у період вегетації до 515,1 мм призводить до зменшення маси 1000 зерен із 45,2 до 38,1 г; за умови підвищення суми активних температур і кількості опадів під час вегетації з 3167,65 до 3202,9 оС та з 413,85 до 515,1 мм можливе збільшення вмісту білка в зерні з 12,4 до 13,8%; у разі збільшення врожайності й маси 1000 зерен із 5,8 до 6,1 т/га та з 51,8 до 53,8 г відповідно вміст білка в зерні може зменшуватися від 13,1 до 12,0%. Висновки. Встановлено різну реакцію сортів на зональні умови вирощування. Виявлено позитивний вплив фактору кількості опадів у період вегетації на врожайність тритикале озимого в Лісостепу та на Поліссі (r = 0,66 та 0,34 одиниці), а також на збільшення вмісту білка в зерні рослин, вирощених на Поліссі (r = 0,56).

Abstract Sugarcane (Saccharum officinarum, Poaceae) is cultivated on a large scale in (sub)tropical regions such as Brazil and has considerable economic value for sugar and biofuel production. The plant is a rich substrate for endo- and epiphytic fungi. Black yeasts in the family Herpotrichiellaceae (Chaetothyriales) are colonizers of human-dominated habitats, particularly those rich in toxins and hydrocarbon pollutants, and may cause severe infections in susceptible human hosts. The present study assessed the diversity of Herpotrichiellaceae associated with sugarcane, using in silico identification and selective isolation. Using metagenomics, we identified 5833 fungal sequences, while 639 black yeast-like isolates were recovered in vitro. In both strategies, the latter fungi were identified as members of the genera Cladophialophora, Exophiala, and Rhinocladiella (Herpotrichiellaceae), Cyphellophora (Cyphellophoraceae), and Knufia (Trichomeriaceae). In addition, we discovered new species of Cladophialophora and Exophiala from sugarcane and its rhizosphere. The first environmental isolation of Cladophialophora bantiana is particularly noteworthy, because this species up to now is exclusively known from the human host where it mostly causes fatal brain disease in otherwise healthy patients.
