06.00.00 Agricultural sciences
DescriptionThe article presents results of the experiment to study the influence of vitamins and minerals preparation with folic acid Vitoligo M at the reproductive functions of sows. It is established that prilificacy of sows was more at 12,5-39,3%. The piglets of the experimental groups had the best quality of growth and livability. Blood chemistry parameters were better in sows experimental groups. The experiment with lots of animals confirmed the results of scientific experience. The sows of the experimental groups had better breeding efficiency

THE USE OF MOLECULAR BREEDING METHODS RESISTANCE TO NET BLOTCH OF BARLEY (REVIEW)
06.00.00 Agricultural sciences
DescriptionIn recent years, due to the increasing aridity there was an increase in the frequency of epiphytoties leaf disease of barley. Therefore, we can see now how greatly increased the need for the creation of resistant grades. Introduction of the selection marker will significantly speed up the breeding process for resistance to pathogens. Employees of the All-Russian Institute of Plant Protection recommended three genes - Rpt 1b, Rpt 5, Rpt 6 to control the resistance to the pathogen Pyrenophora teres for use in breeding programs in the North Caucasus. Rpt 5 gene is one of the most efficient one, because it determines the resistance to the eight isolates of the fungus Pyrenophora teres of different origin. In 2011, Australian scientists have discovered microsatellite markers called Bmag0173 and HVM74, closely linked to the gene Rpt5, which are used very effectively in order to marker-assisted selection of resistant grades in Australia and Canada. Due to the urgency of creating new genotypes carrying resistance genes to net blotch, that would be effective in the Southern Federal Region, the staff of All-Russian Scientific-research institute of Grain Crops after I.G. Kalinenko and the All-Russian Research Institute of Plant after N.I. Vavilov has developed a practical strategy for the use of molecular techniques to create barley grades resistant to this pathogen, which is being successfully implemented

OPTIMIZATION TECHNIQUES FOR PCRRFLP FOR GENOTYPING SHEEP
06.00.00 Agricultural sciences
DescriptionDiagnosis by PCR-RFLP (polymerase chain reaction – polymorphism of the lengths of restriction fragments) is the standard analysis of point mutations for the diagnosis of allelic polymorphism of candidate genes related with productive qualities of farm animals. Along the length of the fragments (RFLP) make a conclusion about the absence or presence of the point mutation, and homozygosity or heterozygosity of the individual. The aim of our work was the optimization of protocols for conducting PCR-RFLP analysis for genotyping sheep for genes of the growth hormone gene differential growth factor and gene of calpastatin

COLLECTION SAMPLES OF SOFT WINTER WHEAT TOLERANT TO LEAF RUST AND POWDERY MILDEW
06.00.00 Agricultural sciences
DescriptionDiseases cause great damage to agriculture, reducing yields and decreasing its quality. The losses are up to 20-30% of potential crop yields. Different types of rust and powdery mildew cause significant damage to wheat. Thereby, the growing of varieties tolerant to these diseases is of great importance at present. It allows solving such problems as the improvement of stability of grain production (especially in the epiphytotic time), improvement of its quality and reduction of prime cost of the product. Cultivation of resistant varieties gives the opportunity to avoid a use of crop protection chemicals and thus, to improve environment. The researches were carried out in the laboratory of intensive soft winter wheat breeding and seed-growing of FSBSI ARRIGC after I.G. Kalinenko in 2013-2015. The crop was sown in a bare fallow. 275 samples of soft winter wheat from the world collection VIR, Turkey (CIMMYT), new varieties of domestic and foreign breeding, varieties and constant selection lines of own selection were the subjects of the study. Favorable for disease development weather conditions allowed evaluating collection samples according to the degree of infection with leaf rust and powdery mildew under natural conditions. According to a complex resistance to leaf rust and powdery mildew we have distinguished the following samples: ‘Nakhodka’, ‘1226/98’, ‘662/99’, ‘1366/08’, ‘Patriarkh’ (Russia); ‘Shestopalivka’(Ukraine); ‘Simonida’ (Serbia); ‘MV 15-04’ (Hungary); ‘Rialto’ (England); ‘Menestrel’ (France); ‘№42 CIMMYT’ (US). Thus, our conducted study resulted in distinguishing the samples of soft winter wheat which are resistant to leaf rust and powdery mildew and are recommended to use as a source of resistance and tolerance to these pathogens. The samples with a combined resistance to both pathogens are of particular interest

CREATION OF INITIAL MATERIAL FOR BREEDING OF WINTER WHEAT VARIETIES TOLERANT TO SMUT
06.00.00 Agricultural sciences
DescriptionThe key task of the agriculture in Russia is the further improvement of grain production. Thus, prevention of losses of winter wheat yields because of the diseases remains relevant. The significance of varieties tolerant to diseases, especially to smut (fungus) is of primary importance. Therefore, it’s essential to create initial material for breeding of the varieties tolerant to smut. According to the results of the trials with artificial infection with pathogens, among the samples of winter wheat there have been identified varieties belonging to different groups of tolerance to smut. They are a highly sensitive cultivar ‘к-69361’ (Korea), a sensitive variety ‘Izyuminka’ (Russia), moderately sensitive variety ‘Asket’ (Russia) and almost tolerant variety ‘1621/03’ (Russia). We studied the reaction of the hybrids F2 on infection with smut in different variants of hybridization to obtain stable progeny. The correlation between the number of infected plants in parent and hybrid (F2) populations have been considered. The productive tillering of the plants has been determined in all variants of the trials; it was the least one on the plants with 100% of infected leaves. The hybrids F3 and F 4 have been distributed according to the degree of their tolerance to smut. For further work we have selected the lines with practical resistance to smut (fungus)

DescriptionThere was given a review of the results of the study in the conditions of sufficient moisture of Central Ciscaucasia, the influence of planting terms and presowing seed treatment by the drug called "TMTDplus", containing Krezatsin growth stimulator in its composition, on the development of corn hybrids of different maturity groups of the selection of Krasnodar Research Institute of Agriculture named after P.P. Lukyanenko (Ross 199, Ross 299, Krasnodar 382 and Krasnodar 410) and the All-Russian Research Institute of Corn (Mashuk 170, Newton, RIC 345 and Eric), as well as middle- maturity population Rossiyskaya 1. The studies were conducted in accordance with the thematic plan of scientific researches of the chair of crop and forage production of the Stavropol State Agrarian University. The soil surface of the experimental station of StavrGAU was presented as leached black soil. The technology of growing of maize on the experimental plot corresponds to the standard one for the present area and cultivar. The predecessor is winter wheat. Sowing was performed in three terms. The first (early) sowing term was carried out at t = + 7 ... +8 ° C. The second (recommended) - when t = + 10 ... + 12 ° C. The third (later) sowing time was carried out at t = +15 ° C. The plant density: early-maturing hybrids – 70 thousand pieces/ha, is mid-maturing ones – 60 thousand pieces/ha, middleripe – 50 thousand piece/ha, middle-later ones – 45 thousand pieces/ha. The scheme is single-row, with spacing of 70 cm. The application of the studied drug TMTD-plus helped to reduce the growing season of maize plants for one - four days. Thus, changing the sowing terms of maize hybrids and populations, we can largely control the development of plants changing the length of the growing season to two weeks and form a harvesting conveyor, thereby reducing the intensity of field work
