Successful cloning of the Sacred Fig tree of Zacchaeus (Ficus sycomora L.), taken by scientists of the All-Russian Horticultural Institute for Breeding, Agrotechnology and Nursery (Moscow) under the auspices of the Imperial Orthodox Palestinian Society, opens the possibility of cultivation of clones of this Christian shrine. Taking into account the natural process of cloning in plant organisms, and on the basis of an expanded understanding of such phenomena as genetic memory, the authors believe that the clones are obtained naturally and retain a certain sacredness of the parent plant. Their cultivation is possible in the conditions of protected ground and open ground. The climatic conditions of Russia make it possible to cultivate the clones of the Sacred Fig tree indoors (climatology, greenhouses, winter gardens) and in the open ground with the protection of the cold season. This is possible only in the sub-tropical region of Russia, as the Black Sea coast (near Sochi). The most suitable conditions for the cultivation of these clones in this region is in the Subtropical Botanical garden of Kuban, Research Institute of floriculture and subtropical crops and Sochi arboretum. The article detailed discuss the technical specifications of the alleged cultivation of clones of the Sacred Fig tree on the example of the Subtropical Botanical garden of Kuban, where currently there are four of the clone submitted for pre-acclimatization in the conditions of the region. With regard to the cultivation of clones of the Sacred Fig tree in its natural form and large size, this is possible only within the range of this species or in areas with similar climatic conditions. This can be the territory of religious sites in Palestine (Israel); Museum and Park complex in Jericho, Sergey town house in Jerusalem, the Cultural and business educational complex in Bethlehem; outside of Palestine - Patriarchal representation of St. Nicholas in Bari (Italy) and St. Nicholas Cathedral in Nice (France).

The article is dedicated to the analysis of activity of scientific-pedagogical schools in the field of fruit growing and viticulture at the Russian State Agrarian University - MTAA named after K.A. Timiryazev in connection with the 150 year anniversary of the University. Such eminent scientists, fruit and grape growers as P.G. Shitt, A.M. Negrul, V.A. Kolesnikov, M.T. Tarasenko, V.M. Tarasov, K.V. Smirnov and many others were worked in the University. The main research results in the development of the biological basis and applied technologies in the nursery-gardening, horticulture, viticulture, their contribution to the scientific support of the profile fields was analyzed. Information on the contribution of the Fruit-growing Department in the field of training for production and scientific institutions, on the structure of educational programs that are implemented at the Department is presented.

Variability of morphological characteristics of C. m. fruits: shape, mass, qualitative and quantitative characters, length of a fruit stem and tear away effort was studied in the population introduced in Novosibirsk. Fruits of C. m. plants have an increased level of variability (V = 21-30 %) for many characteristics, including economically important ones. The establishment of average values of these characteristics allows you to really assess the place of each genotype in the existing diversity and to select the promising individuals for the conduct of remote crosses. The average values of quantitative characteristics and their variability, as well as indicators for the selection of promising genotypes for the most important qualities of fruit were determined. In crossing it is necessary to involve genotypes with the weight of fruit not less than 0,17 g and the score of taste more than 2,5.

The analysis of polymorphism of eleven varieties and pre-selection forms of Persian walnut by two microsatellite loci is spent. Studied varieties and forms of walnut are adapted to the agro-climatic conditions of the North Caucasus and the Kuban regions and are breeding interest as sources of useful adaptive traits. For analysis we used primer pairs WGA069 and WGA202, obtained during the sequencing of the genome of black walnut. These markers were tested on DNA walnut and reported in the literature showed high polymorphism alleles, which led to their inclusion in the work. According to the literature, the range of size PCR products with markers WGA069, WGA202 and do not overlap, which allowed them to be grouped in a multiplex set. Level of polymorphism of two loci allowed to obtain individual SSR-profiles with unique set of alleles for all studied varieties.

The article presents the rationale for the study of economic and biological signs of promising clonal rootstocks, suitable for use in intensive technologies of cultivation of stone fruit crops in order to identify their adaptive capacities in agro-ecological conditions of the Chechen Republic. The experimental data on the duration of rooting, the dynamics of rhizogenic activity, the main phytometric and phytophysiological parameters of various forms of clonal rootstocks of stone fruits on the basis of the research were presented. According to the dimensional parameters of planted in the first field of nursery rooting rootstocks their growth activity is analysed.

The changing of the quantitative and qualitative indicators of black currant harvest according to the age varieties were studied. Influence of the weather conditions on yield and organoleptic qualities of berries has been analyzed. The reasons of fragility of black currant varieties were identified.

The influence of foliar spray applications on the potassium concentration in apple fruit and leaves of Imrus and Sinap Orlovsky was studied in the field experiment. During the vegetation period the applications were done five times according to the following scheme: 1) control (water treatment); 2) H₃BO₃ - 0,1 %; 3) K₂SO₄ - 0,3 %; 4) CaCl₂ - 1 %; 5) H₃BO₃+K₂SO₄; 6) H₃BO₃+ CaCl_2; 7) K₂SO_4.+CaCl₂; 8) H₃BO₃+K₂SO₄+CaCl₂. A signifi cant influence of foliar fertilization on the content of potassium in fruit fl esh and skin was observed. At the same time real differences by years and differences in the responses of studied varieties were observed. The concentration of potassium in fruit flesh of Imrus and in fruit skin of Sinap Orlovsky more changed under the influence of outside root applications of the fertilizers. The potassium content increase in Imrus fruit flesh was observed when treated by H₃BO₃, CaCl₂ and K₂SO₄ as well as by H₃BO₃+K₂SO₄, while K₂SO₄+CaCl₂ had a contrary effect in different years. K₂SO₄+CaCl₂ and H₃BO₃+K₂SO₄+CaCl₂ more effected the content of potassium in fruit flesh of Sinap Orlovsky. In the years of low fruit yields the skin of fruit contained reliably more potassium in those variants than in the control variant but in the years of high yields the potassium content was reliably less. The influence of outside root applications of the fertilizers on the content of potassium in leaves of Imrus was mainly noted in the years with poor yields. In 2011 the potassium content in Imrus leaves increased after H₃BO₃+K₂SO₄ and H₃BO₃+CaCl₂ treatments while in 2013 it reliably decreased. The potassium concentration in the leaves of Sinap Orlovsky did not change much by years and in dependence on the variants of the experiment.

Article is devoted to a comparative evaluation of the chemical composition, quality and yield of fruit of dogwood varieties. It was found that under the conditions of the Tambov region for dogwood varieties it is peculiar the periodicity of fruiting. The maximum yield per tree was observed in varieties Volgogradskiy (17 kg) and Volgogradskiy Grushevidny (16 kg). The variety Volgogradskiy Grushevidny was revealed as a variety with large fruits (the average weight of fruit was 4,8 g). The fruits of dogwood varieties Azerbaijanskiy, Krymskiy were revealed with high content of ascorbic acid and total solids; the fruits of varieties Azerbaijanskiy, Pervenets - with high sugar content; the fruits of varieties Volgogradskiy, Bolgarskiy - with high content of organic acids. The varieties Azerbaijanskiy, Volgogradskiy Grushevidny, Krymskiy and the Pervenets were marked on a complex of economic and biological characteristics.
