Genotypes at the gliadin loci Gli-A1, Gli-B1, Gli-D1 and the high-molecular-weight glutenin subunit loci Glu-A1, Glu-B1, Glu-D1 were identified in 77 winter common wheat cultivars developed in the Central Forest Steppe of Ukraine in different periods of time. The highest level of variation was observed at the Gli-A1 locus. Predominant alleles (one or two(More)
Blocks of gliadin components found both in a number of varieties and in single F2 grains of winter wheat intervarietal hybrids have been studied by two-dimensional electrophoresis combining electrophoresis in acidic aluminium-lactate buffer (pH3.1) and SDS-electrophoresis. Gliadin components (spots) have been shown to be inherited as linked groups (blocks),(More)
The diversity at eight storage protein loci was analyzed in the collection of Triticum spelta accesssions from the National Center for Plant Genetic Resources of Ukraine (most of accessions were European spelts). Seven alleles at the Gli-B1 locus; five alleles at the Gli-A1 and Glu-B1 loci; three alleles at the Glu-B1 locus; and two alleles at the Gli-D1,(More)
Alleles at the high-molecular-weight glutenin subunit loci Glu-U1 and Glu-M(b)1 were analyzed in the tetraploid species Aegilops biuncialis (UUM(b)M(b)). The material for the investigation included the collection of 39 accessions of Ae. biuncialis from Ukraine (the Crimea), one Hellenic accession, one accession of unknown origin, F2 seeds from different(More)
Analysis of F2 grains from two different crosses has revealed a complex organization of the family of gliadin-coding genes located on chromosomes of the first homoeological group in hexaploid wheat. Chromosome 1A of variety 'Bezenchukskaya 98' was found to carry at least five gliadin-coding genes of which three genes form a cluster controlling the synthesis(More)
The review considers the effect of the rye 1BL/1RS translocation in the common wheat genome on qualitative and quantitative traits: grain quality, resistance to diseases, productivity and adaptivity, parthenogenesis, regeneration in anther culture, frequency of chromosome aberrations and frequency of cross-pollination. Data on special features of(More)
The gliadin composition of 78 spring durum wheat varieties has been studied by one-dimensional (Al-lactate, pH 3.1) and two-dimensional (first dimension, Al-lactate, pH 3.1; second dimension, sodium dodecyl sulfate-polyacrylamide gel) electrophoresis. Analysis of hybrids has shown that all components of the alpha zone of gliadin spectra are inherited(More)
The inheritance of alpha-amylases was studied in six F2 populations of hexaploid oats (Avena sativa, A. byzantina, A. fatua, A. sterillis) using polyacrylamide gel electrophoresis. A total of 22 loci was identified and described. Three main linkages of four or five loci each and an additional two pairs of linked loci were detected. It seems likely that the(More)
Inheritance of gliadin components in winter wheat has been studied by one-dimensional polyacrylamide gel electrophoresis. Single F2 grains from 36 intervarietal hybrid combinations have been analysed. The genetic analysis has revealed blocks, including 1-6 gliadin components, which are inherited as individual mendelian traits. About 80 variants of blocks(More)
The particularities of the genetic structure formings of the different genetic systems (biochemical and immunogenetic markers) in the breeds, interbreed crosses of sheep and groups of cattle in connections with the locus, breed and the way of the productivity trait selections were described. The uniqueness of the characteristics and forming mechanisms of(More)
