Description
Professional apple gardening is bound to particular risks, of which is essential losses of a harvest because of diseases. An apple scab, the caused Venturia inaequalis (Cooke) G. Winter, brings the greatest loss. The main approach in monitoring of a scab of an apple-tree is creation of grades, steady against pathogen. In the present work we have carried out phytopathology testing of generations of the seedlings received from the free pollination of six forms of a crab of Malus orientalis from a collection MOS VIR (Maykop) characterized by a relative resistance to the apple scab in 2-3 classes of damage by long-term data. For infection we used inoculum, consisting both of natural population of a scab, and of strains of pathogen of various cultivars and geographical origin. When carrying out padding infection increase in force of an infectious background that can be bound to selection of the plants of biotypes of a fungus that are most adapted for genotypes was noted. It is recommended for precise elimination of unstable plants at selection at early stages of an ontogenesis to carry out more than one serial infection during the season. By results of the phytopathological testing, we highlighted three Malus orientalis forms from the six studied No. 17982, 17985 and 3080 the most perspective stability genes for an introgressiya in a cultural gene pool of an apple tree

The article presents brief results of the introduction of Hibiscus syriacus L. varieties for a signs collection in the south of Russia. Since 2007, Federal State Budgetary Scientific Institution North Caucasian Regional Research Institute of Horticulture and Viticulture (Krasnodar) has been working on the introduction and researching of Hibiscus Syriacus varieties and signs collection is being formed. Introduced varieties of hibiscus are obtained in zones with a moderate temperature-humidity regime, therefore not all are easily adapted in the conditions of the south of Russia. According to the results of the research, several varieties of sources of valuable traits have been identified. Varieties with pure white petals: Totus Alba, William R. Smith, White Chiffon, White Pillar. Varieties with bright crimson color petals: Freedom, Carneus Plenus, Woodbridge, Duc de Brabant. The Blue Chiffon variety is the source of bright blue petals, Sanchonyo is a source of bright purple-crimson petals. Of great value are varieties that have an unusual combination in the color of petals, like the varieties Monstrosus and Hamabo. By the sign: a large flower (d of a flower more than 12 cm), the collection includes varieties White Chiffon, Chaina Chiffon, Pink Giant. Variety Dorothi Crane and hybrids: T-16-11, T-7-11, K-16-12 are identified as sources of round, wheel-shaped flower. With a double flower type, the varieties are represented by varieties: Blue Chiffon, White Chiffon, China Chiffon, Leopoldii, Speciosus, Lucci, Sanchonyo, Freedom, Carneus Plenus. Varieties: Woodbrige, Russion Violet, Ledy Stenly, White Chiffon, China Chiffon, Purple Pillar are sources of abundant long (more than 3 months) flowering. With a high degree of self-purification after flowering, varieties are distinguished: White Chiffon, Sanchonyo, Purple Pillar, White Pillar, Freedom. Varieties: China Chiffon, Freedom, Lucii, Leopoldii, RussionViolet, hybrid forms: T-16-11, T-18-11, T-21- 12 are characterized by increased adaptability to abiotic factors in south of Russia. Dedicated varieties and forms - sources of valuable economic and biological characteristics are of interest for involving in selection and allow to model varieties with given properties

06.01.01 General agriculture, crop production (agricultural sciences)
Description
We have studied 17 strawberry varieties due to their economically valuable traits: the number of berries (pcs per plant), average fruit weight (g), biological yield (g per plant), firmness of fruit (g). Among the studied varieties is 6 - Honeoye, Alba, Belrubi, Asia, Nelli, Bogota are zoned varieties; 3 - Djeni, Elegia, Kemia is a new varieties of local selection and 8 an introduced varieties from the EU - Joly, Onda, Galia, Vivaldi, Rumba, Florence, Alina, Molling Opal. The purpose of the work is to identify the strawberry varieties which are promising for industrial production in the south of Russia among new strawberry varieties of local selection and introduced varieties. Based on two-factorial analysis of variance according to 2018-2019 studies there were revealed significant differences between the genotypes of varieties for all studied parameters. It is shown that the greatest differences in the variability of traits are observed by the “year” factor. The varieties were ranked according to the values of the smallest significant difference for each individual trait. In accordance with the results of the cluster analysis on a complex of traits we have identified strawberry varieties which are showing the prospect for industrial cultivation. In the new varieties of strawberries as Joly, Vivaldi and Rumba the values of yield and quality of berries are comparable to the best zoned varieties, such as Nelli, Asia and Bogota

Description
This article presents the results of testing IRAP DNA markers Cass1 and Cass2 applied to Prunus spinosa. The findings suggest the high perspectiveness of their using for the study of genetic diversity of the gene pool of this species. According to the results of the analysis of the sample 12 genotypes were identified from 6 to 13 fragments in the spectrum of Cass1 and from 5 to 11 fragments for Cass2. As a result of cluster analysis in the sample formed three groups of samples. In one of the groups, which is most distant from the other two, includes samples taken in Ukraine, while the remaining two groups included samples from Armenia, the Krasnodar region region, the Republic of Adygea, Ukraine and Moldova, and three cultural large-fruited form. The distribution of samples in clusters corresponded to their geographical origin that favors the objective assessment of genetic distances between the samples using Cass1 and Cass2 markers. Thus, it was concluded that the prospects of using DNA markers to study the genetic diversity within a species of Prunus spinosa

Description
Sunflower is one of the most important oilseed crops, which are of great economic importance in Russia and in the world. It is very adaptive crop in terms of climatic conditions range, for that reason it is cultivated on a vast territory of the Russian Federation in various weather conditions. Sunflower oil has high nutritional and taste qualities, it is used numerously in food and is applied in various fields of food industry. The biologically active linoleic acid, phosphatides and fat-soluble vitamins A, D, E and K, which are of great nutritional value to humans, are contained in the oil. According to its calorific capacity, sunflower oil is on the first place among vegetable oils. Due to biological characteristics of sunflower, the Krasnodar region is the most favorable region of the Russian Federation for obtaining high and stable yields of this crop. However, here the drought is observed during the summer period and it affects adversely the productivity and quality of sunflower seeds. The increasing of resistance to unfavorable weather conditions is possible only based on detailed study of physiological features of productivity formation and seeds quality that is highly important task in view of the current geopolitical situation in Russia. One way of solving this issue is the appliance of the growth regulators, possessing anti-stress activity that improve the quality of sowing seeds and increase the productivity and plant resistance to stressful environmental factors. These drugs include growth regulator called Furolan, which was created in KubGTU and is certified for use in Russia. It is not toxic and is used in nano-dozes, there is no its residual quantities in the products and environment. Furolan has a positive effect on physiological and biochemical processes, improves the productivity of plants, their resistance to unfavorable growing conditions by increasing the resistance to dehydration as well as to the risk of fungal diseases
