The degree of dominance and the heritability coefficient have been investigated as the markers of allelic interactions of the loci Rht8 and Rht-B1. The interaction is characterized by partial or total dominance or even by overdominance of greater plant height and by low or medium heritability. The alleles that exert a weaker direct negative effect or no such effect predominate over the alleles that predispose to a more pronounced reduction of plant height. The impact of weather conditions on the switch of dominance is discussed. The Kooperatorka line has an additional allele (or alleles) that predisposes to greater plant height; the mode of inheritance of these alleles is partially recessive. An unidentified semidominant gene (or genes) that determines small plant height is present in the genotype of the Odes’ka 3 line. The presence of heterosis related to heterozygosity for certain genes not critically relevant for the present study makes the assessment of the allelic interaction characteristics under investigation more complicated. © 2017, Allerton Press, Inc.

Guard cell size and stomatal density are important interdependent traits (r =–0.67 ± 0.146) of plant adaptive response to environmental stresses. The purposes of this study were to determine the types of inheritance and the number and effects of genes controlling phenotype development of the above-mentioned leaf stomata characteristics. Hybrid F1 values, resulting from crossing by 7 × 7 half diallel crosses and values, and parental midpoints were used. Genetic control of the trait “length of guard cells” is based on the complete domination of the larger length. In the inheritance of “stomata density,” the additive components were significant. It was established that recessive alleles are responsible for the increasing of stomata density (r = 0.93 ± 0.07), and their number was highest in cultivar Odesskaya 16. © 2015, Allerton Press, Inc.

Polymorphism of chs_H1 gene encoding the “true” chalcone synthase of hop was studied by alignment of nucleotide sequences in accordance with the Clustal W algorithm of the MEGA version 5 program and molecular-genetic analysis with the use of polymerase chain reaction. © 2015, Allerton Press, Inc.

Collections of varieties of spring barley cultivars from Eastern European and Central Asian areas were analyzed by exon-specific PCR (EPIC) for β-amylase genes. The endosperm β-amylase gene (bamy1) was differentiated by the presence of 126 bp MITE insertion into intron 3, which is associated with low activity β-amylase. The findings suggest that a low level of genetic variation for bamy1 gene within climatic zones is associated with individual breeding program for each climatic zone. © 2015, Allerton Press, Inc.

The effects of the Rht8c, Rht-B1b, Rht-B1e, and Rht-D1b genes on wheat height have been investigated. Variations in these effects are significantly modified by the genetic background and year conditions. A combination of the Rht8c, Rht-B1a, Rht-D1b, and Ppd-D1a alleles is the most advantageous for the conditions of southern Ukraine, since it is associated with optimal plant height under contrasting conditions within different years. The genotypes of some varieties were shown to include gene(s) that were unidentifiable by the molecular markers and significantly decreased plant height. © 2012 Allerton Press, Inc.

Leaf rust represents the major threat to wheat production in Russia and Ukraine. It has been present for many years and epidemics of the pathogen occur in different regions on both winter and spring wheat. In some regions there is evidence of more frequent epidemics, probably due to higher precipitation as a result of climate change. There is evidence that the virulence of the leaf rust population in Ukraine and European Russia and on winter wheat and spring wheat is similar. The pathogen population structure in Western Siberia is also similar to the European part, although there are some significant differences based on the genes employed in different regions. Ukrainian wheat breeders mostly rely on major resistance genes from wide crosses and have succeeded in developing resistant varieties. The North Caucasus winter wheat breeding programs apply the strategy of deploying varieties with different types of resistance and genes. This approach resulted in decreased leaf rust incidence in the region. Genes Lr23 and Lr19 deployed in spring wheat in the Volga region were rapidly overcome by the pathogen. There are continuing efforts to incorporate resistance from wild species. The first spring wheat leaf rust resistant varieties released in Western Siberia possessed gene LrTR which protected the crop for 10-15 years, but was eventually broken in 2007. Slow rusting is being utilized in several breeding programs in Russia and Ukraine, but has not become a major strategy. © 2010 Springer Science+Business Media B.V.

Aim. Identification of winter wheat varieties from different regions at Xgwm182-5D locus. Methods. Polymerase chain reaction (PCR), gelelectrophoresis. Results. 180 genotypes of winter wheat varieties from Ukraine and Russia selection centers are identified by the locus Xgwm182-5D. There were detected five alleles of this locus, namely 162, 165, 167, 169 and 174 bp. Allele 165 bp was noted to be more common in the sets of investigated varieties in all regions. Allele 162 bp was identified only in the sets of varieties of Southern Ukraine and North Caucasus (20%and 4%, respectively). Allele 169 bp was detected only in varieties of Western Siberia and Volga region. Conclusions. The differences in frequencies of locus Xgwm182-5D alleles may be due to adaptive and breeding value of these alleles for the conditions of certain regions. © Institute of Molecular Biology and Genetics, NAS of Ukraine, 2013.

The loss of resistance to broomrape by the majority of domestic and foreign hybrids, that are resistant to the 5 th race of the parasite (E) in the Black Sea and Azov regions of the country indicates that from about 2004-2005 there appeared new (more virulent) races of the parasite (Orobanche cumana Wallr.). Maternal lines of sunflower hybrids have been developed whose stability to a new race of broomrape is controlled by one dominant gene, Org. These lines have a high ability of combination on the main economic grounds.

Determination of the frost resistance and a microsatellite analysis of the group 5 chromosomes were performed on parental varieties and recombinant inbred lines F 7 Luzanovka odesskaya/Odesskaya krasnokolosaya. The allelic differences of the Xcfd7-5B, Xwmc415-5B, and Xgwm182-5D microsatellite loci were associated with the level of frost resistance of the lines. © 2013 Allerton Press, Inc.

In the south part of Ukraine the haplotype of Rht8c and Ppd-D1 genes is widely distributed among modern bread wheat varieties. During the time of scientific breeding program it has been selected as one of the most important adaptive complexes for plants of this region. The genetic distance between the Rht8 and Ppd-D1 genes was clarified. © 2013 Allerton Press, Inc.
