For the last twenty years, in addition to breeding wheat, PKB Agroekonomik Institute has been working very intensively on breeding other real or bread grains. High-yielding, late winter rye variety PKB Zmaj has been obtained by the pedigree method by a simple crossing of genetically different parents from the collection of PKB Agroekonomik Institute: variety Rtanj and line PKB-R-105. This variety of winter rye combines genes responsible for very high yield potential, resistance to lodging, low temperatures and more significant diseases in the rye. Winter rye variety PKB Zmaj was registered by the Ministry of Agriculture, Forestry and Water Management of the Republic of Serbia in 2018. With the use of optimal agricultural techniques, the variety PKB Zmaj has a high genetic potential for fertility and high adaptation to different climatic and soil conditions.

Nitrogen is an important macro-nutrient that influences various physiological processes in plants . Nevertheless, nitrogen could be loosed from the soil by leaching and evaporation . Thus, low nitrogen inputs are required together with a strategy to improve its utilization by crops . Maize genotypes exhibit various susceptibility to low soil nitrogen . From that reason, variability in the reaction of 32 maize lines to growing in conditions with optimal (fertilization with urea), and with low nitrogen (without fertilization) was examined during 2017 and 2018 . All other growing measures and fertilization with other elements was applied in the same manner on the whole experimental plot . 2017 was a drier season, with higher average temperatures, particularly during anthesis and grain filling period . High variability among genotypes and seasons was present . The values of maize grain yield and 1000 grain weight were slightly higher in treatment with nitrogen application . Some lines under the low nitrogen conditions reached even higher grain yields (efficacy of yielding was 139 .7% and 156 .7%, for 2017 and 2018) than in conditions with optimal nitrogen in the soil, such as L1, L2, L5, L10, L11, L13, L15, L23 and L31, declaring them as genotypes with high nitrogen using efficiency . However, these lines achieved moderate yields (in both treatments and years) in regard to other lines . Among tested lines, L1 and L23 had higher grain yields in both fertilization treatments indicating them as prominent for further research, i .e . breeding of maize hybrids with better nitrogen usage from the soil, even in the conditions with low nitrogen .

Bioethanol is a biofuel that is mostly used as a replacement for fossil fuels worldwide with yearly production reaching nearly 110 billion liters in 2019. Trends of producing this alternative fuel are rising and maize is considered as one of the best renewable raw materials for the production of fuel ethanol due to the high content of starch in the grain. Taking into account that Serbia is one of the most prominent maize producers in Europe, the surpluses of this crop could be directed towards bioethanol production. Even though there is no organized production and consumption of bioethanol as an automotive fuel in Serbia, the Serbian Government has recently introduced some new regulations regarding biofuels. However, due to the reduction of economic activities since the onset of COVID-19 pandemic in 2020, the global demand for crude oil has fallen sharply, negatively affecting the gasoline demand, and thus for bioethanol, which makes the future of this alternative fuel production notably uncertain.

The objective was to assess the effect of chemical desiccation on seed germination and storability in three sunflower female inbred lines and to point at possible indicators for optimal performance time. Desiccation was performed with Diquat (2 l ha-1) applied at 7-day intervals from the end of flowering to harvest maturity. There were 6 treatments and control (untreated). Germination was tested 2 and 21 months after harvest. The highest germination was recorded when the desiccation was performed 35 days after flowering. Results showed that optimal moment for applying chemical desiccation when there is no negative effect on the seed germination is specific for each sunflower genotype. Seeds with a high level of germination (>90%) can be stored for 19 months without significant loss in germination, namely, it was not negatively affected by chemical desiccation. Seed moisture and growing degree-days can be used as reliable indicators for optimal desiccation time.
目的是评估化学干燥对3个向日葵雌性自交系种子萌发和贮藏性的影响，并指出最佳表现时间的可能指标。从开花结束到收获成熟，每隔7天使用Diquat (2 l ha-1)进行干燥。治疗组和对照组(未治疗组)共6例。在收获后2个月和21个月进行发芽试验。在开花后35天进行干燥处理，种子萌发率最高。结果表明，在不影响种子萌发的情况下，化学干燥的最佳时机对不同的向日葵基因型具有特异性。高发芽率(> ~ 90%)的种子贮藏19个月后，萌发率无明显下降，即不受化学干燥的不利影响。种子水分和生长度数可作为最佳干燥时间的可靠指标。

The aim of this research is to study two important factors in wheat production (Triticum sp.) - sowing time and variety, specifically their influence on wheat yield and yield components: the number of grains per spike, grain weight per spike, 1,000-grain weight, and the hectoliter weight. The influence of sowing time and variety were determined based on the obtained data, which indicated the extent to which the significance of these factors manifest on certain components and wheat yield. The optimal sowing date is October 5th-25th. The variety itself cannot give a high yield without the application of all agrotechnical measures, to which we strive for primarily due to the high wheat importance. The experiment set up by the split-plot method in three replications examined three wheat varieties: Gabrio, Rapsodija and Basmati sown in two sowing dates: October 29th and November 25th. The results showed that all yield components (the number of grains per spike, the grain weight per spike, the 1,000 - grain weight, and the hectoliter weight) had the highest values in Rapsodija variety and were more dependent on the variety than to sowing time. The influence of the variety on the hectoliter mass was at a significant level. Wheat yield depended more on sowing time, and the influence of sowing time, variety, and interaction of these two factors on yield were statistically significant. The highest yield was registered in Gabrio variety (8.87 t ha-1), while the average yield achieved by this micro experiment was 8.46 t ha-1.
本研究旨在研究小麦(Triticum sp.)生产中的两个重要因素——播期和品种，特别是播期和品种对小麦单穗粒数、单穗粒重、千粒重和百升重的产量及其构成因素的影响。在此基础上确定了播期和品种对小麦产量的影响，表明了这些因素对某些成分和小麦产量的影响程度。最佳播期为10月5 -25日。如果不采用所有的农业技术措施，品种本身就不能获得高产，我们努力做到这一点主要是因为小麦的重要性很高。该试验采用分块法，分3个重复，分别在10月29日和11月25日两个播种日期播种Gabrio、Rapsodija和Basmati三个小麦品种。结果表明:单穗粒数、单穗粒重、千粒重、百升重等产量成分在油菜品种中均最高，且对品种的依赖程度大于播期。品种对百升质量的影响显著。播期对小麦产量的影响较大，播期、品种及其交互作用对产量的影响均有统计学意义。Gabrio品种的产量最高，为8.87 t ha-1，而本次微试的平均产量为8.46 t ha-1。

The protein content is an important parameter of the technological quality of soybean grain . Therefore, the selection work is aimed at creating a genetic basis for obtaining varieties not only of high yield but also varieties of improved grain quality . In order to provide sustained progress in breeding, it is necessary to find a stable source for breeding for desired traits . The aim of this study was to examine the value of the genotype × environment (G× E) interaction for protein content in 14 Maize Research Institute „Zemun Polje” short-season soybean accessions and to identify stable sources that can be used in breeding for protein content improvement . G×E interaction for grain protein content was analyzed using a linear-bilinear AMMI-1 model . The influence of genotype and environment on the total variation of protein content was approximately equal, while the smallest variation is attributed to genotype x environment interaction . A large number of genotypes with different protein content (Korana, PI 180 507, Kabott, Krajina, Canatto) showed a small contribution to the interaction in studied environments, the most important of which were genotypes with above-average protein content, as potential sources for future breeding programs .

The paper examined the impact of the application of three different phytohormones (INCIT 2, INCIT 5 and INCIT 8, all based on a-Naphthalene Acetic Acid (NAA)), with the cuttings of two forms of Pannonian thyme (the L-16 form, with hairy leaves, and the L-9 form, with hairless leaves), established during two periods (March and May), on the percentage of the rooted cuttings and the morphological properties of the seedlings. As the control, the variant without the application of the phytohormones was taken. The research was conducted in the period from 2019 to 2020, in a plastic greenhouse, using the plant collection of the Institute for Medicinal Plants Research "Dr Josif Pančić", which is located in Pančevo city, Serbia (44°52'20"N; 20°42'06"E; 74 m.a.s.l.). For this research was used the Pannonian thyme species (Thymus pannonicus All.) from the Lamiaceae family, which is grown and produced at the Institute. Plant establishment was carried out in four repetitions with 33 cuttings per each variant. Standard measures of care were used during the period of production of Pannonian thyme. The measurement was performed after 60 days from the date of conducted the experiment. The following parameters were measured: the percentage of rooted cuttings (%), the mass of the rooted plantlings (g), the mass of roots (g), the length of rooting (cm) and the number of root hairs of the formed rootings. The measuring was done using a ruler, millimetre paper and an analytical balance. Given the results achieved, INCIT 2 proved to be the most suitable phytohormone for the rooting of Pannonic thyme cuttings, with the average percentage of rooted cuttings of 61.3%. The lowest rooting percentage was recorded in the control variant, only 29.4%. Satisfactory rooting was found in the cuttings treated with INCIT 8 (57.6%). The L-16 form cuttings showed a higher rooting rate, an average of 53.8%, whereas the L-9 form cuttings had a lower average percentage of rooted cuttings (45.0%) for both plant establishment periods. Greater success and quality in the rooting of cuttings was recorded in the second (May) period of plant establishment, averaging 58.1%, which was higher by 17.4% than the percentage of rooted cuttings in the first establishment period (40.7%). It is important to note that the rooting of the L-9 form was significantly higher in the second establishment period (58.1%) than that in the first establishment period (31.9%).

As the control, the variant without the application of the phytohormones was taken. The research was conducted in the period from 2019 to 2020, in a plastic greenhouse, using the plant collection of the Institute for Medicinal Plants Research \"Dr Josif Pančić\", which is located in Pančevo city, Serbia (44°52'20\"N; 20°42'06\"E; 74 m.a.s.l.). For this research was used the Pannonian thyme species (Thymus pannonicus All.) from the Lamiaceae family, which is grown and produced at the Institute. Plant establishment was carried out in four repetitions with 33 cuttings per each variant. Standard measures of care were used during the period of production of Pannonian thyme. The measurement was performed after 60 days from the date of conducted the experiment. The following parameters were measured: the percentage of rooted cuttings (%), the mass of the rooted plantlings (g), the mass of roots (g), the length of rooting (cm) and the number of root hairs of the formed rootings.
