abstract 1311707003 issue 131 pp. 19 – 28 29.09.2017 ru 3
In recent years, many pigs of specialized breeds, characterized by increased meat qualities, have been brought to Russia from Canada and a number of European countries. The article presents the results of the assessment of slaughter and meat qualities of pigs of different genotypes. Danish pig meat was used as research objects: purebred landrace (CHL), benthic hybrid Landrasx yorkshire (LxY), three-breed hybrid landrace hyorkshire x dyurok (LxXxD), removed from control fattening, and developed prototypes of delicacy products. The commission evaluation of meat and broth showed that the boiled meat from the three breed animals received the highest score, and the quality of the broth significantly exceeded the samples of purebred landrace and two-breed animals. As a result of the tasting evaluation of the Voronezh ham, it was established that the samples of meat from threebreeded pigs, in comparison with the samples from purebred meat, show the most pronounced flavor, aroma and soft consistency

abstract 1311707025 issue 131 pp. 248 – 259 29.09.2017 ru 5
Excess body weight is a serious problem, involving a set of diseases presently. For this reason, taking into account demands of science there was a development of production of food with the lowered energy value for the people having first of all obesity that led to production of substitutes. Even more often producers resort to use of nutritional supplements, which generally receive in synthetic way. In this article, we analyzed multiple references and summarized the material regarding beet fibers. As a result of numerous researches it has been proved that food fibers make favorable impact both on the separate systems of a human body, and on all organism. The use of the minor products of processing of the plant raw material is also critical; they allow improving the preventive properties of products and enriching them with dietary fibers, protein, and mineral elements and also development of food development of curative and preventive action. Citri-Fi food fibers which are received from dried-up orange pulp are well-known, they can keep a large amount of water throughout technological process. They exert positive impact on structure of fat that gives the chance to create a product with the lowered content of fat

DEPENDENCE OF PEACH LEAF CURL DEVELOPMENT ON WEATHER CONDITIONS IN RUSSIAN HUMID SUBTROPICS (APPLYING ASK-ANALYSIS)

abstract 1311707050 issue 131 pp. 572 – 594 29.09.2017 ru 3
In peach orchards of the Russian humid subtropics, leaf curl is the most dangerous and harmful disease. Due to the high degree of danger from the peach leaf curl, for the first time in this region the main task was to analyze peach leaf curl development on weather conditions. In order to solve the problem, it is proposed to apply a new innovative intellectual technology: automated system-cognitive analysis (ASK-analysis) and its software tools - the “Eidos” system. In order to build the model, based on our own observations and the experience of Russian and foreign colleagues, it was decided to use the following factors: the sum of temperatures above +4 ° C of the current year (for the period from January to April), the sum of temperatures above +4 ° C of the previous year (for the whole year), the sum of precipitation of the current year (for the period from January to April), the sum of precipitation of the previous year (for the whole year), the number of hours of infection (in the current year). It was established that such factors as the number of hours of infection, the sum of temperatures above +4 ° C in April and during the period from January to April, as well as the sum of precipitation in March and April, are the most important in the dynamics of peach leaf curl development and spread. High rates of leaf curl spread and development are caused by the number of hours of infection in the range of 1440 ... 2064 hours, as well as by low air temperatures in March and April (the sum of temperatures above +4 °C – 89,4-240,4° and 283,7-316,7°, respectively) and high air temperatures - in January and February (the sum of temperatures above +4 ° C – 155,3-259,6° and 243,5-280,1°, respectively)

RESULTS OF FEIJOA HYBRIDIZATION IN THE HUMID SUBTROPICS OF KRASNODAR REGION

abstract 1311707051 issue 131 pp. 595 – 603 29.09.2017 ru 4
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%).

In the conditions of middle valley of the Lena River on the cryogenic, inundated, cespitose and chernozemic soils different steppe communities differently react on dietary regime. Herb-grass phytocenosis at organic dietary regime is reformed in cereal phytocenosis with the contents of cereals to 76% and bean types 19% of dry basis with productivity to 20 centner of hectare of dry basis. At the same time the efficiency of the improved phytocenosis was on charge exchange energy of 17,3 mega joule of hectare, feed units 1032 and a crude protein of 247 kilo of hectare. The whetgrasses phytocenosis has provided productivity to 19,4 centner of hectare and the content of perevarimy protein in 1 feed unit up to 118 gram. So the most effective for the steppe meadows is using complex fertilizer (humus of 20 tons of hectare + N60P60K60), increasing the productivity twice with a high quality of food

GRAPE VARIETIES OF THE ANAPA AMPELOGRAPHIC COLLECTION AND THEIR USE IN BREEDING WORK

abstract 1311707090 issue 131 pp. 1083 – 1092 29.09.2017 ru 5
In the world, huge work is being done to create global information banks of plant genetic resources. The need for conservation and rational use of genetic resources in modern conditions has become very relevant. Genetic collections are the basis for selection work: creating new varieties, replenishing the assortment with new, classic, introduced and native varieties, adapted to the natural (soil and climatic) conditions of the cultivation sites. In the Anapa ampelographic collection, 4911 varieties of various ecogeographical and genetic origin are represented, the use of which provides great opportunities for creating and breeding new varieties, their state testing and zoning. In the gene pool of the ampelographic collection, most varieties of V. vinifera L. grapes are represented by local honeycombs of different regions of the grape culture, and more than one fourth of varieties of V. vinifera L. are obtained from intraspecific crossings. Despite the value of local varieties of grapes, they do not always meet all the requirements of production. Therefore, to improve the local assortment, it is necessary to carry out selection - breeding new varieties of grapes. This article presents the long-term results of the work on the selection of varieties of table and technical directions in the Anapa ampelographic collection used for breeding. Also, the role of the genetic collection in the creation of new generation varieties by combinative selection is shown - as donors for creating new varieties of grapes. Dedicated varieties are the sources of valuable traits, which are given primary importance and are especially important for the viticulture of the Russian Federation

CENTURY-OLD SIBERIAN STONE PINE CROPS GROWTH AND PRODUCTIVITY IN THE ZONE OF CONIFEROUS-BROADLEAVED FORESTS OF THE MIDDLE VOLGA REGION

abstract 1311707097 issue 131 pp. 1168 – 1180 29.09.2017 ru 5
The purpose of the study was to examine a century of experience of growing of forest cultures of the Siberian stone pine in forest conditions in the region of the Middle Volga. To achieve these objectives, we have investigated old growth culture of Siberian stone pine in the conditions of fresh oak forests in the territory of Rootka forestry of the Mari El Republic. Culture of Siberian stone pine was planted after continuous tillage. The distance between rows was 2,5 m, step landing – 1,0 m. The site was divided into five options, depending on variations in the width of planting strip (I-48 m, II-44 m, in III-40 m, IV - 36 m, V - 32 m). The studies have shown that the Siberian stone pine trees, regardless of the variant, are characterized by good clean ability from twigs, which increases with decreasing of the width of the curtain. It can be noted that in the 100-year-old age, the average height of trees reaches of 28,7 m, an average diameter of 49,8 cm. Stock of forest reaches 795,3 m3 /ha. Best annual increase is observed in growing cultures of cedar in the wings with a width of 40 m and is 7,95-of 7,93 m3 /ha. Based оn the research, we have concluded that Siberian stone pine should be recommended for introduction into the zone of coniferous-broadleaved forests of the Middle Volga region. When creating crops, it is necessary to use larger seedlings and plant density is not more than 1,0 thousand pieces/ha, and the width of the planting strip shall be not less than 40,0 m.
