“…Spelt (Triticum spelta L.) is an old-world crop which was one of the major feed and food cereals of ancient Europe. At the present time it is in the position of a minor crop, but it rightly attracts renewed interest in the field of its relationship to wheat, methods of production, final use characteristics and breeding methods (Campbell 1997). Determination of the spelt wheat HMW glutenin subunits composition was dealt with by RodriguezQuijano et al (1990).…”

Method ISTA SDS-PAGE was used for separation, detection and evaluation of high molecular weight glutenin subunits (HMW) in the different wheat species. The relation has been studied between the HMW glutenin subunit alleles and the bread-making quality of 25 world wheat cultivars and 21 regional varieties common wheat varieties (Triticum aestivum L.), 17 winter spelt wheat (Triticum spelta L.), 3 durum wheat cultivars (Triticum durum DESF.), 9 cultivars of Triticum turgidum L. and 5 cultivars of Triticum polonicum L. The highest frequency of occurrence of HMW glutenin subunits 2*, 13 + 16 and 5 + 10 were found in world wheat cultivars. In Slovak wheat varieties were analysed subunits 0, 7 + 9 and 5 + 10, 2 + 12. The HMW subunits 0, 7 + 8 with Glu-score 4 were determined in Triticum durum DESF. Three electrophoretical profile groups of different HMW glutenin subunits were found in Triticum turgidum L. and Triticum polonicum L. and six electrophoretical profile groups were determined in Triticum spelta L. The verified correlations between bread-making quality and specific HMW subunits of glutenin can be utilised by wheat breeders using SDS-PAGE of proteins as a screening test for the prediction of bread-making quality of wheat. The glutenin proteins of wheat, particularly the highly aggregative glutenin fraction (HMW) strongly influence the bread-making properties of flours. The HMW glutenin subunits are encoded by genes at three genetically unlinked loci Glu-A1, Glu-B1, and Glu-D1, located close to the centromere on the long arm of the homoeologous chromosomes 1A, 1B, and 1D, respectively. There is the significant relationship between the presence and the absence of some specific HMW glutenin subunits and the bread-making quality of wheat varieties (Payne and Lawrence 1983, Payne et al. 1987, Vlasák 1995, aek and Èerný 1997. The most important subunits are 5 + 10 and 2 + 12, which are expressed from Glu-D1 loci. Method of SDS-PAGE is possible to apply for separation, detection and evaluation of high molecular weight glutenin subunits in wheat. KeywordsThe aim of our present contribution was to determine the type of the HMW glutenin subunits and to calculate the Glu-score in the grain of different species of wheat Triticum aestivum L., Triticum spelta L., Triticum durum DESF., Triticum turgidum L. and Triticum polonicum L. MATERIAL AND METHODSThe relationship between the HMW glutenin subunit alleles and the bread-making quality of different wheat species has been studied. The winter wheats included 25 world wheat cultivars and 21 regional varieties common wheat varieties (Triticum aestivum L.), 17 winter spelt wheat (Triticum spelta L.), 3 durum wheat cultivars (Triticum durum DESF.), 9 cultivars of Triticum turgidum L. and 5 cultivars of Triticum polonicum L. which were obtained from the Slovak Republic Genbank and from the Czech Republic Genbank. The cultivars Neepawa, Chinese spring, and Marquist were used as standards.For identification and characterisation of wheat varieties the standard vertical disc...

“…Spelt (Triticum spelta L.) is a hexaploid species of wheat, an ancient and distant cousin of modern wheat (Triticum aestivum L.), and it possesses many genes valuable for conferring tolerance to biotic and abiotic stress, as well as flour quality [26], which could be useful for wheat breeding. As dwarf wheat, Line 3338 is ideal for the study of plant height and QTLs for plant height have been detected using an F 2:3 population derived from Line 3338 and F390 [27].…”

In wheat, plant height is an important agronomic trait, and a number of quantitative trait loci (QTLs) controlling plant height have been located. In this study, using the conditional and unconditional QTL mapping methods, combined with data from five different growth stages over two years of field trials, the developmental behavior for plant height in wheat was dissected. Nine unconditional QTLs and 8 conditional QTLs were identified, of which 6 were detected by both methods. None of the 11 QTLs was detected at all of the 5 investigated developmental stages, but 7 QTLs were detected at certain stages in both years. Further analysis identified 9 unconditional QTLs at different stages, which could explain the phenotypic variation from 4.81% to 17.35%. It was noteworthy that one major QTL designated QHt-4B-2, which was located on chromosome 4B, was detected on May 18 and 25 in both years, and its genetic contributions to plant height ranged from 13.42% to 16.13%. Moreover, of the 8 conditional QTLs identified, six were detected in both years, in the order of QHt-3B→QHt-4B-1→QHt-4B-2→QHt-4D→QHt-5A and QHt-2B expressed at the same developmental stage. The results indicate that QTL expression during plant height development is selective and in a temporal order. As one of the most important agronomic traits in wheat breeding, plant height plays a vital role in producing plants with high lodging resistance and high harvest index. For example, the dwarfism gene from Nonglin-10, which was widely used in classical wheat breeding programs, contributed significantly to the green revolution in the 1960s [1]. Until now, dwarfism breeding has been important in increasing the yield of wheat all over the world. Genetic analysis of plant height has been carried out by many researchers, and more than 20 dwarfism genes have been identified in wheat [2]. Some of these genes have been *Corresponding authors (email: penghuiru@cau.edu.cn; qxsun@cau.edu.cn) exploited to breed many semidwarf cultivars with high yield potential. Recently, along with the advent of molecular quantitative genetics, about 50 quantitative trait loci (QTLs) for wheat plant height have been identified using the constructed molecular genetic linkage maps [3][4][5][6][7][8][9][10][11][12][13][14][15]. However, QTL mapping of plant height in wheat was only focused on the performance of this trait at the maturing stage.Conventional statistical genetic analysis revealed that gene expression patterns were distinct at different developmental stages, and the genetic model for the final character did not fully reflect the true gene expression pattern during formation of the character [16][17][18][19][20][21][22]. Therefore it is necessary to conduct dynamic mapping of plant height at a variety of

“…Uważa się, iż orkisz charakteryzuje się korzystniejszymi właściwościami odżywczymi w porównaniu do pszenicy zwyczajnej, ponieważ zawiera więcej składników mineralnych oraz białka. Przetwórstwo orkiszu jest jednak trudniejsze (łamliwa osadka kłosowa, słaba wymłacalność) i bardziej kosztowne (Campbell 1997;Capouchová 2001). W uprawie orkiszu jednym z problemów jest podatność na wyleganie (Tyburski i Babalski 2006).…”

SummarySpelt is one of the oldest subspecies of wheat, known already from the stoneage. Over time it has been supplanted by modern wheat varieties, but in recent years the cultivation of spelt is undergoing its renaissance. To a large extent this is related to the development of organic farming and increasing interest of consumers in so-called healthy food. Compared with common wheat, spelt wheat grain contains more minerals and proteins, but its processing is more difficult and expensive. One of the problems in cultivation of spelt wheat is susceptibility of winter varieties grown in Europe to lodging. The aim of the two-year field study conducted in the Agricultural Experimental Station Institute of Plant Protection -National Research Institute in Winna Gora was to determine the effectiveness of different growth regulators used in the spelt wheat crops. The following preparations were tested: ethephon, trinexapac ethyl, trinexapac ethyl + chlormequat chloride and prohexadione calcium. The evaluated parameters were: plant height, internodes length and the yield. Shortening effect was observed on all plots with growth regulators used. The best effect was obtained after the application of a mixture of trinexapac ethyl + chlormequat chloride.
