Combining ability with respect to “grain productivity” has been studied among thirty eight self-pollinated lines of maize of mid-early and early maturing in the system of hybrid combinations. The lines with high general (GCA) and specific (SCA) combinative ability have been hybridized. New high heterotic hybrids have
been developed on the basis of lines with high GCA and SCA
In this article the results of the research of quality characteristics of Russian and foreign rice varietieswere observed. A possibility of using the data in characterizing germplasm from the collection was discussed
The article presents methods of industrial tests of the of technical device utility model designed for boilers E-1,0-0,9G-3 QL-500, D-721 of small and medium capacity. The research is aimed at improving the efficiency of fuel combustion in the boiler furnaces due to uniform distribution of airflow when supplying it to the boiler burner
In the work we highlight the organizational and economic
aspects of a profitable pork production in the market conditions. The article provides an analysis of the current status of the pig industry in the Rostov region. It also outlines solutions to the problems of development of pig breeding in the Rostov region
In this article in the light of a common social and philosophical traditions we present two trends, that define connection between science and material production: a trend of dependence of the science development from needs of production, and a trend of
increasingly growing reverse impact of science on material production (along with engineering, technology, innovation). This article analyzes not only the individual elements of the "science-innovationsproduction", but also focuses on the study of the
interaction and the relationship between its elements
The article analyzes the concept and the specific of science, discusses some patterns of functioning, integration and differentiation of modern science. We consider the difference of science and knowledge, nonexistence of sharp distinctions between the terms “science”, “innovation” and “engineering”
There was substantiated the purposefulness of introduction
in non-irrigated organic gardens of apple-trees of Kuban zone of in-row sodding of soil with naturally growing grasses providing the increase of plant resistance to abiotic stressors of summer period and as a consequence, stabilization of generative activity and the increase of fruit productivity
Based on empirical data obtained through the sociological poll, we present the analysis of the identification system of the Krasnodar region. The article places civil, ethnic, religious, regional identity in the hierarchy of the identity of residents of the region, we have also carried out the analysis of subjective importance of the various types of identity
This study was aimed on testing of IRAP markers developed
at plum on varieties of peach, Russian plum and cherry plum and genotyping of home and foreign varieties of plum, followed by an analysis of the data. During the testing of the markers have been identified as a high level of polymorphism between genotypes of plum and between the studied species. On the basis of the results obtained by genotyping 15 samples of Prunus was built dendrogram. Cluster analysis was divided into 3 groups corresponding varieties of P. persica, P. domestica and a common group for varieties of Russian plum and cherry plum
The optimum combination of quantitative and qualitative
relationships between structures of organic and mineral wastes of various industries provides the formation of compound composts, which improves its physical, chemical and biological properties of the soil, helps conserve macro- and micronutrients, organic
matter, enhance ecological niches system, to ensure the
development of ecological trophic groups of microorganisms
