abstract 1261702015 issue 126 pp. 211 – 223 28.02.2017 ru 378
The impact of anthropogenic pollution on soil phytotoxity and on triticale plants in Vladikavkaz suburb was investigated in the work. The objects of the study were sod-gley leached soils and different varieties of triticale plants. The research was conducted in 2010-2011 at the Department of Biology of Gorsky State Agrarian University. The article gives data on microelements content in soils and plants within the range of influence of Vladikavkaz industrial enterprises. There was a marked change of miroelements’ mobility in soil and activity of their penetration into plants during fertilization. The sort characteristics of microelements’ accumulation in vegetative mass of triticale were researched. The conducted research is informative for soil and plant condition monitoring in anthropogenically polluted environment. The work indicates the increasing danger of microelements (including heavy metals) accumulation in soil and their inclusion in biological cycle in concentration that is too toxic for plants, animals and people during the usage of fertilizers, especially their high doses. The most dangerous among heavy metals are mercury, cadmium and lead. We used MPC rate of excess to estimate the content of these metals. The results of the research can be used in soil and cereal plant condition monitoring and diagnosis and in development of regional environmental regulation

SUNFLOWER LOW TEMTERATURE GROWTH RATE EVALUATION CONCERNING BREEDING FOR COLD RESISTANCE

abstract 1181604080 issue 118 pp. 1256 – 1266 29.04.2016 ru 379
One of the prospect directions in new sunflower hybrid development is cold resistance breeding in the emergency stage. Sunflower hybrids with uniform emergency and high rate growth under the low temperature conditions could allow to introduce sunflower in the new regions of our country and so to increase sunflower acreage. The aim of our work was to screen all sunflower available samples for growth rate under the low temperature and to select the best lines and initial material for future breeding. 140 sunflower lines of VNIIMK breeding and hybrid populations on their base were used as a material. Seeds of every sample were incubated during the 10 days in the thermostat under 100 С. Seed germination was evaluated for the each sample along with the seedling size. As a result the most prospective samples were selected for the future breeding work. On the second stage of the experiment one selected population was evaluated on the Breeding station of Vavilov’s AllRussian Research Institute of Plant Industry in the city of Pushkin (Leningrad region). Seeds from the best plants were obtained in this place and will be used for the new lines development. So the effectiveness of selection of sunflower samples for growth rate under the low temperature was verified and this method could be used to introduce sunflower in the new regions of our country with more severe climatic conditions

DEVELOPMENT OF EARLY-RIPENING WHITE CABBAGE VARIETIES IN THE SOUTH OF RUSSIA

abstract 1241610065 issue 124 pp. 1010 – 1019 30.12.2016 ru 379
Early-ripening white cabbage has a special place among the vegetables cultivated in Kuban region. It opens the pipeline of vegetables from the open ground and is supplied to other regions at a time when shortage of vegetables of domestic production is felt the most. Modern producer requirements to domestic hybrids are the highest - product quality, uniformity and productivity should not concede to foreign analogues. Ways to improve the quality of early ripening hybrids: development of lines based on modern foreign hybrids, high uniformity of lines by morphological and economic traits. Development of male sterile lines and dihaploid lines in culture in vitro can more successfully solve the problem of quality of early ripening hybrids. The use of the above methods and approaches helped develop series of inbred lines - gene sources for complex agronomic traits. On the vase of obtained lines promising earlyripening hybrids were developed. One of the hybrids, Ritsa F1, entered the State register of breeding achievements. Advantages of the hybrid: earliness, uniformity and high marketability of heads, high productivity. According to results of contest trial new hybrid Milana F1 is passed for State trial, this hybrid has high productivity potential for growing in sale cropping. Both hybrids were produced with the participation of male sterile line Dt46f, resistant to fusarium. High quality seeds of these hybrids were produced in a greenhouse in direct crop for a wide industrial and environmental testing

RESULTS OF FEIJOA HYBRIDIZATION IN THE HUMID SUBTROPICS OF KRASNODAR REGION

abstract 1311707051 issue 131 pp. 595 – 603 29.09.2017 ru 379
Feijoa crop is valuable due to the complex of useful traits (high frost resistance, big yield, ornamental value and long profitable period). These fruits have delicate flavor, nutritional and dietary properties. The fruits are juicy with a pleasant, gentle, refreshing sweet and sour taste, specific strawberry-pineapple flavor and contain significant quantities of important substances for the human body. Pectin (up to 2.5%), sugars (6-14%), proteins, vitamins, organic acids, mineral salts, etc. are among them. However, the challenge of its cultivation is the lack of cultivars and plantations are represented by a mixture of hybrids originated from free pollination, and characterized by a great variety in biological and morphological traits, differing not only in yield, but in size, shape and yield period. In this connection, the breeders faced the objective to create new cultivars of feijoa, using classical and modern breeding methods and available genetic resources for commercial gardening and production. Development of the core hybrid diversity material and selection of promising forms are the most important stages of the breeding process, providing success of further breeding programs. The breeding of varieties and forms for crossings was carried out according to the principle of combining the desirable traits of the obtained offspring. There are direct and reverse crosses in six combinations ('Dachnaya' x 'Superba', 'September' x 'Superba', 'Dagomysskaya' x 'Superba', 'Superba' x 'Dachnaya', 'Superba' x 'September', Superba ; X 'Dachnaya'). The viability of the pollen was evaluated prior to pollination, by germination on a nutrient medium - 1% agar-agar + 15% sucrose. The degree of fertility varied year by year: in 2015 - 60-62%, and in 2016 - 68-77-88%. The best crossing combinations were established 'September' x 'Superba' and the 'Superba' x 'Dagomyskaya for the creation of the hybrid genepool of Feijoa sellowiana. A high percentage of germination of the feijoa seeds was noted in combinations of 'Dagomyskaya' x 'Superba' (74%) and 'Superba' x 'Dagomysskaya' (70%).

abstract 1211607084 issue 121 pp. 1359 – 1368 30.09.2016 ru 380
Using of seedling method for growing early potatoes accelerates the starting processes of growth and development of plants, and the application of temporary covers of the nonwoven covering materials protects the landing from sudden temperature changes and relapsing frost. To receive seedlings of early potatoes we used standard seed tubers of 60-80 g weigh of the following varieties: Agata, Red Scarlett, Kislovodskiy, Vershininskiy and Sheri. By the time of planting in the ground, depending on the varieties, the height of seedling was from 13 to 26 cm, the number of leaves - 7-10 pieces. Conducting of trial unearthing of potato showed that on 45 days after transplanting into the ground (the second decade of May), it is possible to receive up to 10, 5-11, 4 t/ha (Agata and Red Scarlett varieties). On 55 days (the third decade of May), the yield reached 26, 4 t/ha of standard tubers, and in the first decade of June the yield was from 26, 4 to 50, 6 t/ha. The maximum yield of standard tubers of 50, 6 t/ha was obtained by lifting on 65 days with the Red Scarlett variety. In the terms of the Astrakhan region the growing of early potato by seedling method with using of temporary cover allows to receive the ultra-early harvest of marketable tubers in the II-III decade of May

THE RESULTS OF IMPROVEMENT OF RED STEPPE AND HOLSTEIN CATTLE IN BREEDING FARMS OF THE KRASNODAR REGION

abstract 1211607095 issue 121 pp. 1583 – 1594 30.09.2016 ru 384
The modern cattle breeding in Russia is characterized by dynamic development, development of intensive technologies, increase in production, but at the same time, there are problems of increase in production of milk due to increase of dairy efficiency of cows at the most effective manifestation of the available level of their genetic potential. For the solution of this problem, i.e. for genetic improvement of dairy cattle, creation of new breeds, intra pedigree or zone types, more than 100 thousand of bulls with high genetics, and also 430 thousand heifers were delivered to Russia for the last 10 years. In this regard, the purpose of our researches was to study the level of genetic potential of dairy cows in breeding farms of "Nasha Rodina" of Gulkevichsky region, Vasyurinsky milk farm of Dinsky region, the Firm «Agrocomplex» of Vyselkovskiy region (Gazyrskoye enterprise), "Urozhay" of Kanevskoy region from 2000 to 2014, by using bulls of Golshtinsky breed. Researches have shown that in farms of the Krasnodar region producers with the high level of potential from 10791,0 kg to 12045 kg on milk were yield used on a breeding uterine livestock; from 4,22 to 4,40% of fat; from 3,32 to 3,49% of protein in milk. As a result the level of potential of daughters of bulls and cows in herds of farms was from 7774 to 9144 kg of milk; from 3,89 to 4,05% of fat; from 3,26 to 3,67% of protein in milk. However, genetic potential of new generation of animals is shown not completely. It is influenced by partial compliance of the created technological conditions of biology of animals, and indicators of breeding value of producers, with their prepatent indicators. Calculations of breeding value indexes of bulls – fathers of cows in the herd of "Urozhay" have shown that each bull has its breeding value, an ability to transfer the qualities to posterity. Bulls of Golshtinsky breed of red – motley color ( Pan 2037 and Tulup 78160689), by results of comparison of milk yields of daughters, mothers and contemporaries, had negative prepatent indexes of milk yield and milk protein content (according to F.F. Eysper and V. Sidorova). The data confirm the need of carrying out an obligatory index assessment of bulls before their use on the farm in order to avoid receiving descendants with low dairy efficiency
