Using two microsatellite loci (HaSSR1, HaSSR3), the PCR analysis of the bollworm Krasnodar population was conducted. Molecular-genetic analysis (SSR-PCR) of different geographic codling moth populations by three microsatellite loci Ср1.63; Ср2.39 и Ср2.157 was conducted also. Based on the assessment of the frequencies of occurrence of DNA markers, the molecular-genetic structure was described and genetic diversity in the pest populations was estimated
The results of immunological assessment of winter wheat varieties included in the State register of breeding achievements of the Russian Federation and the variety of different types of resistance to yellow leaf spot pathogen are presented in this article
Chemical and amino acid composition of bare-grained barley was studied. Use of bare-grained barley as a component of compound feeds for young pigs favors the increase of live weight, decrease of food conversion rate and increase of economic efficiency
Nutrient media for shoot development from shoot tips 0.5-0.8 mm with several leaf primordia in four grapevine genotypes were optimized by means of a mathematical design of experiment. Over the range of component concentrations CaCl2 had considerable the highest effect on shoot tip development compared to other components of the media. Grapevine genotypes were different in their needs for concentrations of macro-elements to optimize the process of their growth and development. Shoot development from shoot tips in each grapevine genotype as a function of macro-element concentrations in media must be described by an individual regression equation. The proposed method of result evaluation and the mathematical design of experiment may be used in physiological and agricultural research for optimization of processes affected by numerous factors. The optimized media for shoot tip development may by used for sanitation of grape plants from viruses in meristem cultures
The development of leaf spot pathogens (yellow leaf spot and septoria spot) has been studied in Belarus and North Caucasian Region of Russia. The resistant wheat cultivars to the pathogens have been revealed
The analysis of qualitative indicators of Don selected soybean varieties aimed to determine a possibility of their usage in processing industry is carried out. An evaluation of chemical and organic leptical indicators of soybean seed quality and physical properties is made. Possible directions of Don selected soybean varieties usage in processing industry are determined
In the process of scientific and economic experiments on broiler chickens to enhance the physiological and productive effect of growing broiler chickens on grass-soy diets, it is recommended to include the inhibitor of mold “toxins nil” to reduce the risk of aflatoxicosis
The article presents the result of correlation analysis of harvest structural elements. They have been analyzed for their effect on the biological yield inbred lines. The distribution of inbred lines in terms of manifestation of each trait separately was made. The final step was the evaluation of hybrids and calculation of economic efficiency of their implementation. As a result of the work, three hybrid combinations of corn were selected, and studying in further strain testing was suggested
The article gives an overview of the study results in the terms of Anapo-Taman zone of the Krasnodar region. It shows treatment effects of the growth stimulants of Avibif and Biodux on Saperavi vine and its productivity and quality
In the article we show the investigations of aromatic wine produced from grapes of Sauvignon blanc grown in AF South in Temryuk District. As a result, the article estimates obtained good organoleptic characteristics of the taste, within 7.3-7.9 points, which is higher than the passing score. It was found that the greatest negative impact on the formation of mutual organoleptic properties have such flavors as metilatse-tal and the amount of volatile acids
