Coriander is a multi-purpose essential oil plant that has various growing purposes: to obtain essential and fatty oils, to use it as a spice and a green herb. Coriander is a leader in the production and consumption of essential oils. The largest cultivation region in Russia is the Central Blackearth Region. The current work has shown the possibility to grow coriander in the conditions of the Rostov region and has revealed the best genotypes adapted to insufficient humidity. There have been studied 124 coriander collection samples according to various economically valuable traits. There has been presented a range of their variation by the growing season duration from 84 to 106 days, by the plant height from 42 to 80 cm, by yields from 26.5 to 250 g m2, by essential oil percentage from 0.56 to 2.15%, by oil content from 18.9 to 25.4%, by oil yields from 21.4 to 56.5 g/m2, by 1000-kernel weight from 5.2 g to 7.4 g. The paper also shows the conditions to form their greatest values. There have been identified the samples “K-298”, “K-259”, “K-284”, “K-272”, “K-179” with the most valuable set of economic features that can be revealed under various conditions. There have been selected the coriander samples “K-428”, “K-298”, “K-284”, “K-272”, showing high seed yields under free flowering and under isolators. There has been established a fruit formation coefficient (0.16–0.45) taking into account free flowering and insulators, and there have been selected the samples showing a lesser degree of oppression under insulators (with a fruit formation coefficient of >0.3).

Pea (Pisum sativum L.) is one of the ancient and valuable high-protein leguminous cultures in the world. Breeding of new high-yielding cultivars is the main reserve to increase production of pea seeds. At the present time, intraspecific hybridization has a great importance in selection of new cultivars of pea. However, consistent patterns of inheritance of a number of economically valuable traits by hybrids are still insufficiently investigated. The objective of this research work was to study inheritance of seed size (1000-kernel weight) by pea hybrids of the first and second filial generations (F1, F2). The crossing and back-crossing (reciprocal crossing) were conducted. In our experiments, the first filial generation hybrids (F1) had a lower 1000-kernel weight than the large-seeded parental cultivars. Herewith the large-seeded genotype of the female parental cultivar had more influence on displaying of this trait in hybrids than of the male parental cultivar. In the second filial generation hybrids (F2) showed intermediate inheritance of seed size. The results of our experiments attest high efficiency of seed size selection in segregating generations of hybrids, obtained from crosses between cultivars carrying genes of seed size.

The practice of using wild-growing material in the breeding of forage crops has long been recognized as a relevant and effective method for creating new varieties. The purpose of the research was to assess wild-growing samples of the crested wheatgrass and isolate genetic sources of economically valuable traits for breeding in the Stavropol Territory. The research was carried out in 2017–2020. The material of the study – 22 wild specimens of crested wheatgrass (Agropyron pectiniforme Roem. et Shult.) of various ecological and geographical origin. The crested wheatgrass variety ‘Vikrav’ served as the standard. During the years of study, meteorological conditions were extremely dry. The assessment of the samples was carried out according to the guidelines for the selection of perennial cereal grasses. The experiment was laid on bare fallow, plot area – 3 m2. Sowing and maintenance work were carried out manually. On average, for three years (2018–2020), the yield of green mass of the studied samples ranged from 0.15 to 0.94 kg/m2; dry – from 0.07 to 0.38 kg/m2; seeds – from 0.015 to 0.070 kg/m2. Samples from Ukraine (d.d. 28, 30), Chelyabinsk region (d. 31) and Kazakhstan (d.d. 34 and 37) were more productive in terms of fodder weight. In terms of seed productivity, in the first year, wild samples from Aktobe (d. 5) and Chelyabinsk regions (d. 31), from Ukraine (d. 25) and Kazakhstan (d.d. 34 and 37) were distinguished. In the second year of herbage use – from the Chelyabinsk region (d. 31) and Kazakhstan (d.d. 35 and 37). In the third year of use, no significant excess over the standard was found. On average, over three years of use, wild specimens d. 31, d. 34, and d. 37 exceeded the standard in seed yield by 0.020-0.033 kg/m2. Wild specimens from the Chelyabinsk region (d. 31) and Kazakhstan (d. 34) were isolated according to the complex of valuable characteristics for use in breeding in the Stavropol Territory.

Aim and task: Goals and objectives: to form a conveyor of industrial assortment of peach and nectarine for the Crimea and southern Russia. To do this, study the new varieties of peach and nectarine bred by the Nikitsky Botanical Gardens for a complex of economic and biological characteristics. The study of varieties was carried out according to the "Program and methodology for the study of varieties of fruit, berry and nut crops" (Sedov, 1995), as well as in accordance with the classifier (Khloptseva, Sharova, Korneichuk, 1988). 34 new varieties of peach and 7 - nectarine of NBG selection of different ripening periods were studied by a complex of economically valuable traits. Genotypes with a complex of outstanding properties in terms of yield, frost resistance of flower buds, drought resistance, resistance to fungal diseases, and commercial qualities of fruits with an increased content of biologically active substances have been identified. A conveyor belt of a new industrial assortment of peaches and nectarines of the Nikitsky Botanical Garden selection for gardening in Crimea and southern Russia has been proposed.

The researches were conducted on fields of OOO NPO “Triumph”, the Matveevo-Kurgansky district of Rostov region and V.S. Pustovoit All-Russian Research Institute of Oil Crops, Krasnodar in 2017–2020. The purpose of the research was to develop methodology of selection of self-fertile sunflower genotypes in foundation and breeder seed production. Our work resulted in development of improved population Dobrynya plus. Middle self-fertility of this population at self-pollination was 13.7% vs. 5.2% of the initial variety (increased by 2.6 times), a ratio of the most valuable genotypes with amount of fully formed seeds more than 150 seeds per a plant increased from 13.5 to 26.4% (by 1.9 times). At the open flowering and free insect pollination, population Dobrynya plus does not differ by its economically valuable traits from the initial variety. But at the close flowering, without insects pollination, yield of the population Dobrynya plus was 0.93 t per ha vs. 0.52 t per ha of the initial variety (increase by 1.8 times). At selection of elite seeds from sunflower varietal populations for seed growing, the most perspective are the biotypes with high level of self-fertility which traits are held stable in the different environments. Improvement of sunflower variety by 11 self-fertility does not lead to decreasing of its yield qualities by the main economically valuable traits. The obtained experimental data prove a prospectivity of researches directed on improvement of sunflower variety populations by self-fertility at production of foundation and breeder seeds and possibility to reach successful results.

In 2017–2019 we conducted researches in NPO “Triumph”, Matveevo-Kurgansky district, Rostov region, and in fields of V.S. Pustovoit All-Russian Research Institute of Oil Crops, Krasnodar. The purpose of the research was to develop methodic questions of selection of self-fertile biotypes during production of foundation seeds of confectionary sunflower varieties. We stated self-sterile and semisterile consist the main part of the studied seven OPvarieties and are equal 68.5% in average. They vary from 60.3% in the Enisey variety to 75.0% in Dobrynya. Basing on our researches we proposed a rating scale for self-fertility level in sunflower varieties and a scheme of foundation seeds growing oriented for selection of biotypes with increased selffertility. We developed a promising varietypopulation Dobrynya+, its average self-fertility of plants is equal to 12.2% comparing to 6.5% of the initial variety. A share of the less valuable self-sterile biotypes in it decreased from 22.2 to 12.0%, and a portion of the most valuable highly self-fertile, contrariwise, increased from 13.9 to 18.0%. By a complex of the other economically valuable traits a population Dobrynya+ does not differ of the initial variety.
