The Correlation of Temperature-Mineral Phase Transformation as a Controlling Factor of Thermal and Mechanical Performance of Fly Ash-Based Alkali-Activated Binders.

This research focuses on an evaluation of mineral phase and structure transformations in Class F fly ash-based geopolymer systems. The research also studies the strength response of geopolymers when exposed to temperatures between 25 and 800 °C. The purpose of this research is to understand the processes that occur in alkali-activated systems within a wide range of high-working temperatures.

[Molecular-genetic analysis of maize mitochondrion regions associated with cytoplasmic male sterility].

Molecular-genetic polymorphism of 86 world and Ukrainian breeding maize lines with S-, C- and T-types of cytoplasmic male sterility (CMS) and with normal wild type mitochondrion has been researched via mitochondrion regions PCR-analysis. Molecular marker system allowed to detect and identify definite type of CMS within maize lines, as well as to differentiate lines with definite CMS type either from lines with another CMS type or from normal wild type cytoplasm lines.

[Modern biotechnologies in estimation of genetic diversity of Ukrainian varieties of hop (Humulus lupulus L.)].

Genetic variety estimation of hop gene pool using DNA-typing of highly polymorphic microsatellite loci and optimization of introduction to the culture of in vitro conditions is the important stage of national varieties resources forming, basis of modern nursery and protect mean of varieties property, and also it is necessary for development of molecular methods of selection of planting-stocks free from pathogens.

[Molecular-genetic analysis of sorghum cultivated in Ukraine].

PCR-analysis of intraspecific and interspecific polymorphism of sorghum, soryz and their nearest relatives (maize, rice) has been conducted. The level of polymorphism within the sample was 100%. Interspecific polymorphism (species of sorghum and soryz) was 96.

[Marking of the loci encoding maize resistance to Fusarium].

Genotyping of F2-population from crossing of maize lines Odesskaya 139 and R221 contrasting on Fusarium rot resistance has been carried out. Codominant DNA-marker RGA11 to the locus determining Fusarium resistance was found out at the distance of 18.3 cM.
