На підставі аналізу архівних матеріалів 55-річнихспостережень Миргородської сортодільниці Пол-тавської області встановлено залежність ураженняпшениці озимої бурою листковою іржею від часувідновлення весняної веґетації (ЧВВВ) рослин та пе-ріодичності сонячної активності. ЧВВВ є комплекс-ним показником наступних світлових, теплових і,частково, водних умов весняного розвитку рослин,що зимують. Максимальне ураження посівів буроюіржею (57–81 %) спостерігалося в роки з середньоюсонячною активністю (61–120 W) за оптимального іпізнього ЧВВВ. Мінімальне ураження, яке не потре-бує застосування заходів захисту, спостерігалося задвох поєднань цих показників: 1) у роки з раннімЧВВВ (до 20 березня) незалежно від сонячної актив-ності і 2) в роки високої сонячної активності (121–190 W) за слабкої залежності від ЧВВВ. Таких роківбуло 28 із 55-ти. Отримані результати можутьбути використані в прогнозуванні розвитку буроїіржі пшениці озимої. It is determined the dependence of winter wheat affection by brown rust to time of plants’ springrevegetation (TSRV) and to periodicity of solar activity on 55-years observations Myrgorod selectionfield of Poltava region. Time of spring revegetation is a complex index for following light, thermal andpartially water conditions of plants’ spring development, that winter. Maximum sowing affection bybrown rust was observed in years with average solar activity (61-120 W) under optimum and late time ofspring revegetation. Minimum affection that doesn’t demand protection agents application was observedin combining of two factors: 1 – in years with early time of spring revegetation (till 20th of March) andnot depending on solar activity and 2 – in years with high solar activity (121-190W) and lightdependence from time of spring revegetation. Such years were 28 between 55. Obtained results can beused in prediction of brown rust development on winter wheat.

Winter Wheat Varieties

The purpose of the current work was to study the winter wheat varieties artificially infected with the North Caucasian population of brown rust to identify a damage degree. The study was carried out in two stages on two sets (8 and 10) of varieties with different level of resistance to the pathogen. The trials have established a high damage degree of rust on susceptible varieties, which resulted in productivity decrease from 16.3 to 32.2%. Among the varieties with the maximum damage degree, there was identified the most resistant variety ‘Tarasovskaya 29’ which, when completely (100%) damaged by the disease, showed a minimum productivity decrease, no more than 10.6%. The varieties being poorly susceptible to brown leaf rust reduced the productivity from 11.2% to 20.7%. The smaller indices of productivity decrease among this group were shown by the variety ‘Spartak’. Among the five varieties that showed moderate leaf rust damage, there were different degrees of productivity decrease. The variety ‘Donskaya Yubileynaya’ artificially infected with brown rust, showed a minimal productivity decrease and its structural elements, and it could be identified as the leaf rust resistant variety like the variety ‘Tarasovskaya 29’. When predicting the brown leaf rust epiphytoty, the susceptible and half-resistant wheat varieties require obligatory protection with fungicides.

Winter Wheat Varieties

New varieties of soft winter wheat have been submitted for state scientific and technical expertise: Krasunya Poliska, Mokosha, Pyriatynka, Fortetsia Poliska, Efektna – in 2018, Zemlerob and Lyubito – in 2020. The best varieties in 2020 were Efektna – 6.87 t/ha, Pyriatynka and Zemlerob – 6.56 t/ha each, Fortetsia Poliska – 6.48 t/ha. During 2016-2020, all the varieties undergoing qualification examination exceeded the Lisova pisnia standard in terms of yield (5.97 t/ha). Thus, the yield of the Fortetsia Poliska variety was 7.31 t/ha, Pyriatynka – 7.10 t/ha, Zemlerob – 7.06 t/ha, Krasunya Poliska – 6.95 t/ha, Lyubito – 6.72 t/ha ha, Efektna – 6.36 t/ha, Mokosha – 6.27 t/ha. It is worth noting the significant variation in the yield over the years of research in all varieties submitted for further study and registration for state scientific and technical examination. At the Panfil research station, the yield of soft winter wheat varieties Mokosha and Zemlerob exceeded the standard in terms of yield – 6.4 t/ha, Fortetsia Poliska – 6.1 t/ha and the Efektna variety was not inferior to the standard – 5.9 t/ha. Brown rust damage during 2016–2020 was lower compared to powdery mildew. It was found that the Efektna variety had a very high resistance to both powdery mildew and brown rust. Very high resistance to brown rust was observed in 2020 for all varieties that were submitted for variety testing. It was found that the incidence of leaf septoria during 2016–2020 was high compared to brown rust and powdery mildew. The cultivar Zemlerob was selected, which had both a stable lesion (Min = 7 %) and a weak susceptibility (Max = 28 %). It was found that in the snowless 2020 and in the abundant rainfall of 2018, the defeat of septoria leaves had moderate resistance (X = 15.81 %) and (X = 20.03 %). Studies have shown that in 2020 a very high resistance to septoria of the ear was observed in the variety Fortetsia Poliska. In the Pyriatynka, Efektna, Lyubito varieties, the development of the disease was noted to be 1.0 % and the spread of the disease in the area – 10.0 %.

Comparison of Disease Occurrence and Green Leaf Area (GLA) of Winter Wheat Depending on the Forecrop and Differentiated Fungicidal Protection UsedThe effect of the forecrop and differentiated chemical plant protection on the intensity of fungal leaf diseases of winter wheat were studied from 1999-2008. Five (I-V) separate experiments were conducted in Mazury (Szestno I,), Żuławy Wiślane (Lisewo II), and Powiśle (Wielgłowy III, IV and Radostowo V). The intensity of diseases varied. Powdery mildew (Blumeria graminis) was noted in relatively low or trace intensity. On the other hand, there was a large amount of necrotic leaf spot complexes caused byMycosphaerella graminicola, Stagonospora nodorum, Pyrenophora tritici-repentisandFusariumspp. In 2000, 2001 and 2003 brown rust (Puccinia recondita) was noted in high intensity. The applied treatments were very effective in reducing fungal disease on leaves. The surface of the upper leaves (Green leaf area - GLA) with no symptoms of infection and fungicide use were significantly higher than in the control. It was also found that the GLA of crops grown after oilseed rape was higher than the GLA of crops grown after wheat.
