Abstract The purpose of this study is to evaluate the condition of a collection of Bulgarian common wheat varieties under ex situ controlled storage after a ten-year period. The studied materials are characterized by high vitality, without negative changes that will lead to the loss of original germplasm. The established moisture in the seeds is high for the purpose of controlled storage. When it rises above 12,5%, a decrease in the values of germination energy is observed. Higher control of initial moisture and germination is required prior to entering the seeds for storage under ex situ conditions.

Aim. The aim of the study was to investigate genetic variability of gliadin-coding loci Gli-A1, Gli-B1, Gli-D1 in Ukrainian winter common wheat landraces and obsolete varieties. Methods. APAG electrophoresis of gliadin was used to identify genotypes at Gli-1 loci. Results. Diversity at the Gli-1 loci of 41 winter common wheat landraces, including local varieties Krymka, Banatka, Girka, Theyka, and 13 obsolete winter common wheat varieties, were studied. A total 31 gliadin alleles (including new 7 alleles) were revealed. There are 11 alleles at the Gli-A1 loci, 14 - at the Gli-B1, 6 -at the Gli-D1. Differences in frequencies of gliadin alleles were established. Conclusions. The high level of allelic variation at the Gli-1 loci was observed in Ukrainian winter common wheat landraces. Predominant alleles were revealed: Gli-A1m (46,8 %), Gli-A1d (21 %), Gli-B1b (47,1 %), Gli-D1g (45,8 %), Gli-D1a (33,3 %), Gli-D1j (13,9 %). In genotype of modern Ukrainian winter common wheat are present only 3 of them - Gli-B1b, Gli-D1g, Gli-D1j, which positively relate to dough quality.

Abstract The main purpose of this research was the identification and characterization of low-molecular-weight glutenin subunit (LMW-GS) composition in common wheat and the determination of the effect of these proteins on the rheological properties of dough. The use of capillary zone electrophoresis and reverse-phase high-performance liquid chromatography has made it possible to identify four alleles in the Glu-A3 and Glu-D3 loci and seven alleles in the Glu-B3 locus, encoding LMW-GSs in 70 varieties and breeding lines of wheat tested. To determine the technological quality of dough, analyses were performed at the microscale using a TA.XT Plus Texture Analyzer. Wheat varieties containing the Glu-3 loci scheme (Glu-A3b, Glu-A3f at the Glu-A3 locus; Glu-B3a, Glu-B3b, Glu-B3d, Glu-B3h at the Glu-B3 locus; Glu-D3a, Glu-D3c at the Glu-D3 locus) determined the most beneficial quality parameters.
