Abstract
Durum wheat breeding relies on grain yield improvement to meet its upcoming demand while coping with climate change. Kernel size and shape are the determinants of thousand kernel weight (TKW), which is a key component of grain yield, and the understanding of the genetic control behind these traits supports the progress in yield potential. The present study aimed to dissect the genetic network responsible for kernel size components (length, width, perimeter, and area) and kernel shape traits (width-to-length ratio and formcoefficient) as well as their relationships with kernel weight, plant height, and heading date in durum wheat. Quantitative Trait Locus (QTL) mapping was performed on a segregating population of 110 recombinant inbred lines, derived from a cross between the domesticated emmer wheat accession MG5323 and the durum wheat cv. Latino, evaluated in four different environments. A total of 24 QTLs stable across environments were found and further grouped in nine clusters on chromosomes 2A, 2B, 3A, 3B, 4B, 6B, and 7A. Among them, a QTL cluster on chromosome 4B was associated with kernel size traits and TKW, where the parental MG5323 contributed the favorable alleles, highlighting its potential to improve durum wheat germplasm. The physical positions of the clusters, defined by the projection on the T. durum reference genome, overlapped with already known genes (i.e., BIG GRAIN PROTEIN 1 on chromosome 4B). These results might provide genome-based guidance for the efficient exploitation of emmer wheat diversity in wheat breeding, possibly through yield-related molecular markers.

Abstract
Triticale (× Triticosecale Wittmack) is of great interest as an insurance crop that can ensure the stability of the gross harvest of feed and food grains at a lower cost. In Western Siberia, only winter triticale varieties are cultivated, however, spring triticales are important for cultivation in regions not suitable for winter crops. To create spring varieties with high yields and good grain quality, it is necessary to study and enrich the gene pool, identify donors of economically valuable traits. One of the possible ways to solve this problem can be through the production of secondary hexaploid triticales with the involvement of the tetraploid wild-growing species of emmer wheat Triticum dicoccum (Schrank) Schuebl. The aim of this work was to create and study hybrids of emmer T. dicoccum (Schrank) Schuebl. with hexaploid triticale using genomic in situ hybridization for staining of meiotic chromosomes and analysis of plant productivity elements in F4-F8. DT4, DT5, DT6 plants and the prebreeding F6 forms obtained from them - DT 4/168, DT 5/176 and DT 6/186 - were selected according to the characteristics of the productivity and the nature of the grain in the F4 hybrid population. The offspring of hybrids DT4 and DT5 and prebreeding forms DT 4/168 and DT 5/176 had an increased grain nature (over 750 g/l), but low productivity. The hybrid DT6 and the breeding form DT 6/186 obtained from it had high grain productivity (785 ± 41 and 822 ± 74 g/m2, respectively), but, like the paternal form of triticale UK 30/33, had a reduced nature of the grain. In F8 DT 6/186 plants, 7 homologous pairs of rye chromosomes and from 27 to 30 wheat chromosomes were found in meiosis, which indicates the presence of a complete rye genome and two wheat ААВВ genomes. Rye chromosomes showed stable formation of bivalents in contrast to wheat chromosomes, which caused the presence of aneuploids in plant populations. Thus, hexaploid forms DT 4/168 and DT 5/176 with well-made smooth grain and high grain size were obtained, which can be used as a source of this trait for selection of food-grade triticale. DT 6/186 is a promising form for further breeding in order to obtain high-yielding forms of triticale.

Abstract
The aim of this study was to improve the nutritional value and functional properties of noodles with the utilization of different primitive wheat and also whole egg. For this purpose, flours of two different primitive wheat (Triticum monococcum and Triticum dicoccum) were used in noodle formulation replaced with wheat flour at 0%, 25%, 50%, 75%, and 100% ratio. Physical, chemical, textural, and functional properties of noodles were investigated. Noodle production was carried out with and without whole egg, and the effect of egg on noodle properties was also investigated. Noodle containing Triticum dicoccum showed higher levels of protein, fat, antioxidant activity, and total phenolic content compared to Triticum monococcum-containing samples. Whole egg usage significantly (p < 0.05) affected the ash, fat, protein content, antioxidant activity, total yellow pigment, color value (L*, a* and b*), and cooking properties of noodle samples. The increased ratio of primitive wheat flour significantly improved the overall measured chemical properties of the noodles. Sensory analysis showed that primitive wheat had closer sensory scores to each other, and their usage above 50% affected sensory parameters negatively, on the other hand, the use of egg in noodle formulation had a positive effect on all parameters.

Abstract
In this work, we studied the effects of in vitro oxidative stress applied by H2O2 to maize pollen germination and cytosolic Ca2+, taken as an experimental model to test the biological activity of extracts of emmer (Triticum turgidum L. spp. dicoccum (Schrank ex Shubler) Thell.) wheatgrass obtained from grains sprouted with distilled water, or salinity (50 mM) or selenium (45 mg L-1 of Na2SeO3). Wheatgrass extracts were obtained in two ways: by direct extraction in methanol, which represented the free phenolic fraction of extracts (Ef), and by residual content after alkaline digestion, which made it possible to obtain extracts with the bound fraction (Eb). Comparative tests on maize pollen were carried out by differently combining H2O2 and either wheatgrass extracts or pure phenolic acids (4-HO benzoic, caffeic, p-coumaric and salicylic). The cytosolic Ca2+ of maize pollen was influenced by either H2O2 or pure phenolic acids or Ef, but not by Eb. The negative effect of H2O2 on maize pollen germination and cytosolic Ca2+ was mitigated by Ef and, slightly, by Eb. The extent of the biological response of Ef depended on the sprouting conditions (i.e., distilled water, salinity or selenium). The extracts of Se-biofortified wheatgrass were the most effective in counteracting the oxidative stress.

Abstract
Several food products, made from hulled wheats, are now offered by the market, ranging from grains and pasta to flour and bakery products. The possibility of verifying the authenticity of wheat species used at any point in the production chain is relevant, in defense of both producers and consumers. A chip digital PCR assay has been developed to detect and quantify percentages of hulless (i.e., common and durum wheat) and hulled (i.e., einkorn, emmer and spelt) wheats in grains, flours and food products. The assay has been designed on a polymorphism in the miRNA172 target site of the AP2-5 transcription factor localized on chromosome 5A and involved in wheat spike morphogenesis and grain threshability. The assay has been evaluated even in a real-time PCR system to assess its applicability and to compare the analytical costs between dPCR and real-time PCR approaches.

Abstract
The fermentation of Triticum dicoccum with sourdough enhances the nutritional aspects of the final product by the enrichment of several compounds with potential medical and biological activity, hence, could improve the health of consumers. This study analyzed the chemical composition of fermented spelt flour from Garfagnana (Province of Lucca, Tuscany) by 1H Nuclear Magnetic Resonance (1H NMR) spectroscopy and its in vitro antioxidant properties by FRAP and DPPH tests. Beyond this, the ex vivo CAA-RBC assay determined the cellular antioxidant activity on human erythrocytes under oxidative condition. Carbohydrate reduction was observed, while amino acids, organic acids and aromatic compounds with potential antioxidant activity increased during the fermentation time. Moreover, both in vitro and ex vivo outcomes showed an improved antioxidant profile. As a possible industrial application, the fermentation process adopted in this research could be reproduced on a large scale for the commercialization of the products by the food industry.

Abstract
Biostimulants improve yield, quality, and stress acclimation in crops. In this work, we tested the possibility of using phenolics-rich extracts from spelt (Triticum dicoccum L.) husks to attenuate the effects of salt stress (100-200 mM NaCl) in maize. Two methanolic extracts were prepared from the soluble-conjugated (SC), and the insoluble-bound (IB) phenolic acid fractions of the spelt husk, and their effects were investigated on several stress-associated biochemical parameters, such as proline, lipid peroxidation, H2O2, GSH levels, and ion content. Results show that SC and IB fractions of husk extracts behaved very differently, no doubt due to their greatly divergent chemical composition, as revealed by both GC-MS and HPLC analyses. The efficacy of treatments in mitigating salt stress was also dose- and timing-dependent. IB, even at the lower concentration tested, was able to recover the performance of stressed plants in terms of growth, photosynthetic pigments content, and levels of salt stress markers. Recovery of shoot growth to control levels and reduction of stress-induced proline accumulation occurred regardless of whether plants were pre-treated or post-treated with IB, whereas only pre-treatment with the higher dose of IB was effective in mitigating oxidative stress. Although in some cases SC and even methanol alone exerted some positive effects, they could also be deleterious whereas IB never was. Overall, results indicate that a polyphenol-containing extract obtained from spelt by-products can behave as biostimulant in maize plants and can mitigate their response to salt stress, by acting on different biochemical targets.
