Relevance. The modern marrow seed market shows the prospect of creating F1 hybrids that have the maximum return on a high-quality crop. For their successful selection, parental forms with a complex of economically valuable traits and a high combinational ability are required. The most important role is played by the female zucchini maternal lines of flowering type, which allow for hybrid seed production with free pollination and obtain high quality F1 hybrid seeds.Materials and methods. The studies were carried out at of the Krymsk EBS VIR Branch (Russia, Krasnodar Region, Krymsk) in 2019-2021. Variety testing of lines and hybrids was carried out in the open field in the fields of selective crop rotation. The plot area was 5 m2, the experiment was repeated three times.Results. The general combinative ability of parental squash lines was studied, maternal forms with a positive GCA effect on early yield (F5 409-1, F5 409-2) and on total yield (F5 409-1) were identified. A preliminary variety testing of hybrid combinations was carried out in comparison with the standards F1 Belogor and F1 Pascal. The main economically valuable traits have been studied: early maturity, early and general yield, marketability, product attractiveness. F1 hybrids of zucchini were identified, obtained on the basis of maternal forms of the female type of flowering F5 409-1, F5 409-2 in terms of yield (early above 17,7 t/ha and total above 46,7 t/ha), and marketability, more than 83,2%.Conclusions.

Relevance. In the Western Siberia conditions bulb onion is grown mainly from onion sets. With this method of cultivation, large costs are spent on growing and storing the onion sets. In this regard, the cultivation of it through the seeds is of particular importance. This problem has not been studied enough in Priobskaya zone of Altai Territory conditions.Materials and methods. In our research, we studied the influence of cultivation conditions on the formation of economically valuable traits of varieties and a hybrid of bulb onion grown by sowing seeds in the ground in Priobskaya zone of Altai Territory. Three varieties were taken as objects of research: Odnoletniy Sibirskiy, Zolotnichok, Odintsovets, and one Candy F1 hybrid.Results. On average, over the years of research on early maturity, the standard Odnoletniy Sibirskiy variety (87-88 days) showed itself to be the most early maturing. Candy F1 hybrid can be used as a source of early green mass. Leaf regrowth was the earliest of all onion samples studied. The largest leaf apparatus in the conditions of Priobskaya zone of Altai Territory is formed by the varieties Odintsovets (4.1 pieces per plant) and Odnoletniy Sibirskiy (3.8 pieces per plant). The maximum bulb mass was formed by the Candy F1 hybrid (51.5 g). The Candy F1 hybrid also was distinguished by the highest yield in the group of the studied samples. The increase in total yield was 5.1 t/ha, marketable 2.4 t/ha in relation to the standard. The maximum marketability in the experience was in the standard (80.9%).

Bread Wheat Variety

There has been presented the characteristics of the new early-maturing winter bread wheat variety ‘Zhavoronok’ according to economically valuable traits and properties. The development of early-maturing grain crop varieties is one of the main issues of grain production. The combination of a relatively short vegetation period with high productivity in one genotype helps to solve a number of agricultural concerns. This allows using techniques more systematic, reducing the intensity of harvesting and yield loss significantly, which occur when cultivating simultaneously maturing varieties on large areas. The purpose of the current study was to evaluate the new early-maturing winter bread wheat variety ‘Zhavoronok’ on the basis of a set of economically valuable traits. The study was carried out in 2015–2019 with such forecrops as maize for grain, weedfree fallow, peas and sunflower. In the department of winter wheat breeding and seed production of the FSBSI Agricultural Research Center “Donskoy” a lot of work is being done on winter wheat breeding, and one of the important directions is the development of early-maturing varieties. The winter bread wheat variety ‘Zhavoronok’ has been included in the State List of Breeding Achievements of the Russian Federation since 2020 and approved for use the North Caucasus and Nizhne-Volga regions. According to the length of the growing period, it belongs to the early-maturing group. Its high and stable productivity with various forecrops is explained by a complex of positive economically valuable traits and properties, such as high productivity of a head, resistance to lodging and brown rust, high frost resistance (the same as that of the variety ‘Don 107’). The variety ‘Zhavoronok’ is capable of producing good yields and full grain in arid years, its early maturity allows it to ‘escape’ drought, disease and other unfavorable conditions.

The article reflects the results of work on the mobilization, conservation, replenishment and study of genetic resources of grapevines of the Don ampelographic collection named after Ya.I. Potapenko (Novocherkassk, Ros-tov region) in 2019. Mobilization, conserva-tion, replenishment and study of plant bio-diversity, identification of new and assess-ment of stocks of used species, is gaining theoretical, scientific and practical signifi-cance, and is currently relevant. Most of the native and sparsely distributed grapevine varieties are now preserved only through col-lections. The process of grape selection is closely related to the need to preserve and replenish collections, since this is the main base for large-scale ampelographic and ge-netic selection works, which are currently effective and very effective in science and production and thus practically significant for the Russian grape-growing industry. Cur-rently, the preserved gene pool of grapevines in the collection includes 870 varieties, the collection is supplemented with 5 new grape varieties (Suholimanskij belyj, Traminer be-lyj, Granatovyj, Dostojnyj, Mriya). Two sources of economically valuable traits for high-quality wine – making were identified: Laсukere and Neizvestnyj donskoj varieties.

Under conditions of climate change, the assessment of the stability of genotypes is of particular importance. To conduct directed selection of genotypes with a narrow or broad reaction rate, it is necessary to assess their stability already in the early stages of breeding. The aim of the study was to study the stability of breeding significant traits of oat and barley samples in contrasting ecological and geographical conditions. 25 oat samples and 25 barley samples were studied over 3 years under contrasting conditions in St. Petersburg and the Tambov region. Varieties are characterized by average values of economically valuable traits and genotype regression coefficients on the influence of the bi environment according to Eberhart and Russell. The most sensitive to a change in the ecological and geographical situation were the durations of the germination-heading, germination-harvest periods and grain yield. These characters varied to a greater extent depending on the cultivation conditions than on the genotype. According to regression coefficients for environmental conditions, significant differences in genotypes were only in yield. Contrasting groups of varieties were distinguished by regression coefficients on environmental conditions, genotypes with high productivity. The durations of germination-heading, germination-harvest, the plant height reacted to the change in the environment the same in different varieties. The duration of the growing season was determined by the sum of effective temperatures above 15C. The reduction of the growing season in both crops was 3 days with an increase in the sum of effective temperatures above 15C by 100C.

The objective of this work was to investigate heterosis and its components in 16 white grain maize populations presenting high quality protein. These populations were divided according to grain type in order to establish different heterosis groups. The crosses were carried out according to a partial diallel cross design among flint and dent populations. Seven agronomic traits were evaluated in three environments while four leaf diseases and incidence of corn stunt were evaluated in one. Least square procedure was applied to the normal equation X'Xbeta = X'Y, to estimate the model effects and their respective sum of squares. Among the heterosis components, in diallel analysis, significance for average heterosis in grain yield, number of days to female flowering and to all evaluated diseases was detected. Specific heterosis was significant for days to female flowering and resistance to Puccinia polysora. Results concerned to grain yield trait indicate that populations with superior performance in dent group, no matter what flint population group is used in crosses, tend to generate superior intervarietal hybrids. In decreasing order of preference, the dent type populations CMS 476, ZQP/B 103 and ZQP/B 101 and the flint type CMS 461, CMS 460, ZQP/B 104 and ZQP/B 102 are recommended to form composites.
