The purpose of the research was a preliminary estimation of ten experimental hybrids of winter rapeseed (Brassica napus L.) bred in the V.S. Pustovoit All-Russian Research Institute of Oil Crops by the primary economically valuable traits. The research was conducted in the central zone of the Krasnodar region in 2019–2020. The results of the research are presented for the first time. On average for two years, nine of ten the best experimental hybrids increased by seeds yield by 0.32–0.76 t per ha both the standard cultivar Loris and the foreign hybrid Mercure. Middle seed yield of the studied hybrids varied significantly, variance range was from 4.99 t per ha (VN-3 × ОРK-10) to 5.62 t per ha (VN-4 × ОРK-20). Maximal values of seed and oil yields per a unit area were fixed for a hybrid combination VN-4 × ОРK-20. Except that, the hybrid is characterized with high weight of 1000 seeds (4.5 g). A hybrid combination VN-13 × ОРK-10 demonstrated high average by years seeds yield (5.33 t per ha) and oil yield (2.25 t per ha).Oil content in seeds and weight of 1000 seeds of this combination were at the level of the standard cultivar and the foreign hybrid. This hybrid shows the lowest glucosinolate content in seeds – 16.7 µmol/g, that is less that the foreign hybrid Mercure has by 2.3 µmol/g. The preliminary conclusion based on our researches is: the selected hybrids after confirmation of the competitive trial results can be of a great interest for production.

The main receptacle of essential oil in true lavender is the peltate glandular trichomes of the calyxes in the whorls of the inflorescences. Their average size is 175 ± 25 µm, in some cases – up to 250 µm. For the extraction of lavender oil, not only the calyxes are used, but the whole inflorescences including the flowering shoots. The surface of the peduncles of lavender inflorescences is also covered with peltate glandular trichomes. However, their contribution to the total volume of essential oil in the inflorescence has almost never been determined. The aim of this research was to study the distribution density of glandular trichomes within the inflorescence and to determine the proportion of the contribution of flowering trichomes to the formation of essential oil in the inflorescence. The research was carried out in 2021 on the basis of the V.S. Pustovoit All-Russian Research Institute of Oil Crops in two ecological and geographical points of the Krasnodar region. The object of the study was the true lavender varieties Voznesenskaya 34, Rannyaya, Yuzhanka and Voznesenskaya Aroma. It was found that the size of glandular trichomes on peduncles of true lavender is 90 ± 15 µm. Their number on peduncles, depending on the variety, varies from 2141 to 3003 pcs. The density of distribution of glandular trichomes on the surface of peduncles is equal to 8.60–14.93 pcs/mm3 . The total volume of essential oil in all glandular trichomes of peduncles is 0.41–0.57 cmm . The total volume of essential oil in the inflorescences varied from 2.28 to 5.15 cmm . The share of essential oil in the glandular trichomes of the peduncles in relation to the entire inflorescence ranged from 9.33 to 19.56%. It is concluded that peltate glandular trichomes on flower-bearing axes make a significant contribution to the essential oil content of lavender inflorescences. For the selection of true lavender to increase the essential oil content and the yield of essential oil, an additional selection trait is proposed – the amount of glandular trichomes on the surface of peduncles, which can be regulated by changing their distribution density on the surface of peduncles, or increasing the length of inflorescences.

The ways of penetration of pathogenic bacteria from the infected vegetative parts of plants into soybean seeds remain practically unexplored. It is widely believed that soybean seeds are infected through the vascular system from already infected areas of the vegetative parts. The aim of the present research was to study the possibility of penetration of pathogens of bacterial blight into soybean seeds through the conductive tissues of plants. The studies were carried out in 2019–2021 in V.S. Pustovoit All-Russian Research Institute of Oil Crops on plants and seeds of soybean variety Vilana. It was found that the size of stomatal slots in soybean leaves is 8–12 µm. This ensures free penetration of bacteria with a diameter of 1.3–1.7 µm into the leaf mesophyll. The pore sizes of the sieve plates of the phloem range from 0.4–0.7 to 0.8–1.6 µm, depending on the age of the plants. The largest pores of the phloem sieve plates are comparable to the diameters of pathogenic bacteria. However, a large number of transverse sieve plates located in the vessels of the phloem every 0.05–0.1 mm will filter and partially retain bacteria in each sieve tube along the path of cell sap in the phloem. Therefore, the pathogenic bacteria passing through the entire phloem from leaves infected with bacteriosis up to pods is physically unlikely. In pods, the vascular system ends in the area of attachment of the placenta to the seed hilum. In the hilum, there are no conductive tissues, and the further flow of water and nutrients into the seed is carried out diffusely through the plasmodesma of cell walls. It was found that the anatomical structure of the soybean phloem prevents the free movement of pathogenic bacteria along the conductive system directly into the inner tissues of the seeds. Therefore, the hypothesis of infection of soybean seeds with pathogens of bacterial blight through the conducting system of the plant should be considered untenable

One of the factors limiting high and qualitative yields of sunflower seeds is pests. Phytophages injure plants of the crop during the whole vegetative period causing growth and development disorders, and sometimes plants depth. Together, insects play the important role in distribution of pathogens, especially fungi from genera Alternaria, Fusarium, Rhizopus, and Puccinia, as well as bacteria. Among phytophages on sunflower, the most harmful are herbivorous bugs (class Hemiptera) of fleahopper (Miridae) and stinkbug (Pentatomidae) families. Bugs feeds on plants sap, they suck it out of the different plant organs. The basic oil crop in the Krasnodar region is sunflower. In 2021 its sowing area accounted to 442 thousand ha. Breaks of scientifically substituted cultivation technology lead to deterioration of phytosanitary state of sunflower crops by means of concentration of pathogens, including herbivorous bugs. The purpose of the research was to determine species and prevalence of bugs and their dominating species in sunflower crops in the Krasnodar region for the further development of protection measures. The result showed in the central zone of the Krasnodar region the sunflower crops are inhabited with 12 species of bugs from the families: Miridae, Pentatomidae, Alydidae and Coreidae. Prevalence of tarnished plant bug (Lygus pratensis (Linnaeus, 1758) and bishop bug (Lygus rugulipennis (Popp., 1911) was high (60 and 80%, respectively), and sloe bug (Dolycoris baccarum (Linnaeus, 1758) was maximal – 100%. A sloe bug prevailed in sunflower crops – 36.1%.

Breeding of winter rapeseed in the V.S. Pustovoit All-Russian Research Institute of Oil Crops was started at the end of 60th of previous century with a selection of perspective winter forms from hybrids of spring brown mustard and winter rapeseed. Heterosis in intraspecific hybrids was studied. The best intraspecific hybrids exceeded the parental forms by 20–36% by seed yield, by 20–27% by green mass yield. A possibility to create intervarietal hybrids based on heterostyly was studied. Conditions for plants acclimation to increase cold resistance of winter rapeseed were studied; methods of selection for cold resistance were developed. In 1982, the development of rapeseed and turnip rape cultivars of ‘00’ type began. To create diversity of breeding germplasm, a great amount of samples from European counties that actively deals with rapeseed breeding were included into the work. In the V.S. Pustovoit All-Russian Research Institute of Oil Crops, the methods of estimation of oil and fodder protein quality were perfected, cultivars of rapeseed and turnip rape of ‘00’ type (e.g. erucic acid free and with low glucosinolate content) were developed. As a result of breeding for oil quality, high oleic cultivars were developed, that not only improve upon the oil nutritive efficiency but open new possibilities of its technical uses due to increasing oxi- and thermostability. The first Russian high oleic winter rapeseed cultivar Olivin was developed in the V.S. Pustovoit AllRussian Research Institute of Oil Crops and introduced in the State Variety Commission in 2019. The linear cultivars of winter rapeseed were developed by inbreeding, the first interlinear hybrids – using a CMS Ogura system. One of them named Debyut was introduced in the State variety trials 2020.

The article provides a brief analysis of the results of plot and field experiments to study the productivity (yield) of sunflower, depending on the area of plant nutrition, performed at VNIIMK. Based on the analysis of the experimental dependencies that determine the change in yield, the following statement is applied: yield (y) and its increase rise with an increase in the amount of growth factor (x) and are proportional to the amount of yield (A - y) that does not reach the maximum the limiting value (A), and the possible yield value (B + y), is higher than a certain minimum (initial) value (B) of the yield. The analytic formulas for the quantitative determination of yield value (у), maximum limiting yield (A), amount of nutrients in soil, a rate of action of growth factors, etc. are present for the first time. These formulas allow studying many problems of soil management in certain hydro-temperature conditions and landscape. The samples of accounts due to the new methodology which showed good correspondence between test and theme data are presented.

The researches were conducted on fields of a farm “Berezanskoe”, Korenovsk district, Krasnodar region. Size of a plot is equal to 112 sq. м, in three replications. The object of the research was F1 seeds of interlinear sunflower hybrid Fakel produced in 2020 with different positive modifications on a hybridization plot. The seed were planted in 2021 to estimate impact of the positive modifications (methods) on yield and quality seeds of the hybrid Fakel in progeny. Two sowing rates (60 and 80 thousand per a га) were used to realize fully a yield potential of the hybrid. A certain positive impact was fixed in variants with application of biological protection measures and microbiological fertilizers during plants vegetative period. Yield increase was 0.02 t per ha. Increase of oil content and oil yield of the hybrids Fakel in progeny under different positive modifications was insignificant: 0.2–0.3% and 0.01–0.02 t per ha, respectively. Application of biological protection measures and microbiological fertilizer during the vegetative period of plants on the hybridization in 2020 contributed in a profitability increase by 6% when sowing F1 seed in 2021 with sowing rate of 80 thousand seed per ha.

To obtain high yields of good quality of sunflower seeds, it is necessary to strictly observe scientifically justified cultivation technology, which combines techniques accounting both the biological features of the crop and the natural and climatic conditions of the region. But the role of varietal agricultural technology is also great, which takes into account the properties of a new variety and ensures the fullest realization of its productivity potential under these conditions. Research and development data are very important when introducing crops or varieties into new regions. In this regard, it became necessary to study and scientifically substantiate the optimal seed sowing rates of Russian sunflower varieties in irrigated conditions of the Uzbekistan Republic. The effect of seed sowing rates on the growth, development and yield of Russian oil sunflower varieties was studied in 2020– 2021 at the experimental station of the Tashkent State Agrarian University of Uzbekistan. The objects of the research were promising varieties Irtysh, Skormas (Russia) and the local variety Dilbar (Uzbekistan), which were cultivated at different seed sowing rates, providing a plant population of 40, 50, 60 and 70 thousand plants per ha. As a result of the studies, we found out, according to the complex of economically valuable traits, the best varieties of oil sunflower in the conditions of the Tashkent region are the middle maturing variety Dilbar of the local selection and the ultra-early maturing variety Skormas of the Russian selection, they formed the highest yield in the main crops on irrigation with a seed sowing rate of 50 thousand plant per ha – 4.35 and 4.09 t per ha, respectively. The Russian variety Irtysh is ultra-early maturing, the growing season is 86–88 days, it is less productive and can be considered as promising for repeated crops.
