Purpose. Comparative studies of the photosynthetic apparatus of winter wheat varieties of modern and earlier breeding in the relation to their productivity. Methods. Field, pot experiment, biometrical, gas analysis, analytical and statistical ones. Results. It is found that the modern high-yielding winter wheat varieties have a higher rate of flag leaf photosynthesis during generative period of development, particularly at grain filling period, improved ability to store assimilates in stem and effectively use them later for grain growth. The modern varieties form crop canopy with greater leaf area and chlorophyll indexes and larger photosynthetic capacity and maintain functional activity of photosynthetic apparatus longer at the end of the growing season. Conclusions. The superiority for grain productivity of modern high-yielding wheat varieties, originated from the Institute of Plant Physiology and Genetics, NAS of Ukraine, over varieties released before the “green revolution”, results from increased capacity and durability of functioning the crop photosynthetic apparatus, higher CO2 assimilation rate and optimization of source-sink relations in whole plant.

Oats technological indices have been analyzed. Influence of growing conditions on natural weight, kernel size, and hoodness is established. The study summary indicates essential dependence of natural weight and hoodness and precipitation at the stage of grain formation in coated grain oats varieties. Moisture supply in the period of grain formation essentially influenced the percentage of coated grains formation and natural weight score in naked grain varieties. Morphometric analyzes of oats caryopsis was completed using the method of machine vision. Correlation between technological indices and morphometric characteristics of naked and coated grain of oats was determined. Also, essential dependence of hoodness on 1000 seeds weight and the lack of essential correlation with morphometric characteristics of the calliopsis were established. Calliopsis width essentially influenced the weight of 1000 seeds. Metric indices of naked grain oats calliopsis exposed close correlation with kernel size and natural weight. Weight of 1000 seeds exposed essential varietal distinctness and was determined by genetic peculiarities of varieties

Purpose. To enrich and improve the range of table grape varieties of Ukraine. Methods. Breeding, hybridological, mathematic, visual ones. Results. Modern Ukrainian gene pool of table grape varieties has been created on the base of the best introduced and homegrown cultivars and selections. New genotypes that are creating at the National Scientific Centre “Institute of Viticulture and Wine-Making named after V. Ye. Tairov” under the breeding program “Resistense plus Quality” are the basis of current and future regional assortments for the south and central areas of the steppe zone of Ukraine. The complexity of the origine explains the genetically determined high-level manifestation of commercially valuable characters. New varieties and selections are ecologically safe for humans and the environment, as the level of their resistance to the group of fungal main diseases is not less than 6.5 points according to the 9-point scale, therefore they do not require a large pesticide load. New promising table varieties demonstrate a stable yield and high marketability of grapes – 5–10 kg per plant with the marketability nearly 80–87% during the last five years. In addition, dense flesh of grapes is a guarantee of high transportability. The variety of table genotypes taste, shape and berries ripening from very early to very late embodied in the innovative and highly profitable development “Conveyor of table grapes”. Depending on the ecological and geographical conditions, the conveyor can include a different quantity of varieties, but to in order increase the efficiency and profitability it is necessary to have a few groups (from 2 to 4 varietes) of different ripening. The approximate ratio (%) of varieties of different ripening time is recommended: very early – 22%, early – 22%, average – 17%, mid-late – 17%, and late – 22%. Conclusions. The variation of shape, flavour and color of new promising genotypes of table grapes makes them very popular on the market and may satisfy the most demanding consumer. The stability of the adaptive and technological traits makes the new table varieties very attractive for the producers of grape products.

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.

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.

Purpose. Assessment and selection of self-pollinated S5 maize (Zea mays L.) families with high combining ability and wide adaptive capacity obtained on the basis of specially produced hybrids by crossing elite lines of various genetic plasms with the best main agronomic characters. Methods. Field studies, mathematico-statistical evaluation. Results. An amplitude of grain yield ranging from 5.96–10.96 t/ha (x = 8.44 t/ha) in 2013 to 2.67–7.59 t/ha (x = 5.08 t/ha) in 2014 was determined in the course of study of the testcrosses of self-pollinated S5 families. It was found that different response of genotypes of the studied testcrosses to the year conditions significantly affected the average yield level, which decreased in the stressful 2014 by 3.4 t/ha as compared to 2013. The results of the assessment based on the general and specific combining ability of new parent material of mixed germplasm were shown. A significant variability of the estimates of GCA (general combining ability) effects depending on the year conditions was observed in the course of study. A marked difference in the estimates of GCA effects based on the grain yield was revealed. They were persistently high in 19% of the best self-pollinated families in both years, 14% of the families had persistently low estimates of GCA effects, 67% changed their value depending on the genotype and year conditions. Conclusions. 17 best self-pollinated families with persistently high estimates of GCA, 6 families featuring high tolerance to drought and 4 families with persistently high variances of SCA were selected. The selected families will be used as a parent material in selection programs aimed to create new high performance hybrids.

Мета. Дослідити формування продуктивності сорту сої культурної ‘Говерла’ за використання різних елементів технології вирощування. Методи. Польові, лабораторні, статистичні (розрахунковопорівняльний, математичностатистичний). Результати. Встановлено ефективність весняного чизелювання за вирощування сої культурної сорту ‘Говерла’ в ґрунтовокліматичних умовах Прикарпаття. Відзначено позитивний вплив досліджуваних способів обробітку ґрунту на фітосанітарний стан посівів. Зокрема, поєднання зяблевої оранки з весняним чизелюванням за внесення мінеральних добрив N30P30K30 та дворазового позакореневого обприскування посівів регулятором росту зумовило підвищення конкурентоздатності рослин проти бур’янів та знизило чисельність останніх на 46,2%, як порівняти з контролем. Виконання вищевказаних дій також сприяло збільшенню врожайності до 2,48 т/га, або на 57,0%, у середньому за три роки. Водночас зріс вихід кормових одиниць та перетравного протеїну – на 1,35 і 0,3 т/га відповідно. Висновки. Весняне чизелювання разом із зяблевою оранкою та раціональним поєднанням у системі удобрення побічної продукції попередника, запропонованих доз мінеральних добрив і регулятора росту в умовах Прикарпаття сприяли зниженню забур’яненості посівів на 46,2% та підвищенню врожайності сорту сої культурної ‘Говерла’ на 57,0%. | Purpose. To study the formation of the productivity of the ‘Hoverla’ soybean variety using different elements of cultivation technology. Methods. Field, laboratory, statistical (calculationcomparative, mathematicalstatistical). Results. The effectiveness of spring chisel ploughing for the cultivation of the soyabean variety ‘Hoverla’ in the soil and climatic conditions of the Prykarpattia region was established. The positive effect of the studied tillage methods on the phytosanitary condition of the crop was noted. In particular, the combination of autumn ploughing and spring chisel ploughing with the application of N30P30K30 mineral fertiliser and double foliar spraying of crops with a growth regulator led to an increase in the competitiveness of plants against weeds and reduced the number of weeds by 46.2% compared to the control. The implementation of the above measures also contributed to an increase in yield to 2.48 t/ha, or 57.0% on average over three years. At the same time, the yield of forage units and digestible protein increased by 1.35 and 0.3 t/ha respectively. Conclusions. Spring chisel ploughing, together with autumn ploughing and a rational combination of the predecessor’s byproducts, the proposed doses of mineral fertiliser and growth regulator in the conditions of the Prykarpattia region, helped to reduce the weediness of crops by 46.2% and increase the yield of the ‘Hoverla’ soybean variety by 57.0%.
