“…With regard to climate change mitigation strategies in bioenergy cropping systems, triticale (X Triticosecale Wittmack), safflower (Carthamus tinctorius L.), and canola (Brassica napus L.) can play important roles as potential bioenergy crops, since they can grow on marginal lands with low inputs in terms of irrigation and fertilizers. Triticale has a high adaptability and tolerance to abiotic and biotic stresses [27]. It has a well-developed extensive root system, which can allow it to grow well in low-fertile, marginally fertile, and sub-standard soils as well as in dry areas [28,29].…”

Using wastewater in agriculture is a desirable alternative source of irrigation and is gaining attraction worldwide. Therefore, this study was designed to assess the effect of treated municipal wastewater (TWW) and groundwater (GW), along with half and full doses of the recommended NPK dose on the plant growth, total biomass, gross energy, and macro- and trace element content and uptake of safflower (Carthamus tinctorius L.), canola (Brassica napus L.), and triticale (X Triticosecale Wittmack) grown in old and virgin soil as potential bioenergy crops. The results showed that crops planted in old or virgin soil irrigated with TWW had higher values of plant height, leaf area per plant, total chlorophyll content, total biomass, and gross and net energy contents compared to those irrigated with GW grown in virgin soil. Similarly, crops grown in old soil irrigated with TWW showed higher concentrations in dry matter and uptake for both macronutrients (N, P, and K) and trace elements (B, Zn, Mn, Cu, Cd, Pb, and Ni) compared to those planted in virgin soil and irrigated with GW. Furthermore, the application of the recommended half dose of NPK in old and virgin soil irrigated with TWW showed occasionally comparable results to that of a full recommended dose of NPK for most of the measured parameters. Importantly, the recommended half dose applied to old soil irrigated with TWW resulted in a significant improvement in all measured parameters compared to virgin soil irrigated with GW, along with a full recommended dose of NPK. Briefly, TWW can be used to irrigate crops grown for bioenergy purposes, since it did not pose any harmful effect for energy crops. In addition, it provides additional nutrients to soil and thus decreases the required rate of synthetic fertilizer by up to 50% without any significant decreases in the final production of crops.

“…Triticale (x Triticosecale Wittmack) is a man-made cereal developed by crossing wheat (Triticum aestivum L.) and rye (Secale cereale L.) with a genomic constitution of 2n = 6x = 42 (Ayalew et al 2018;Mergoum et al 2019). It combines valuable traits like high fertility and grain quality received from wheat with high resistance to diseases, drought, low temperature, higher tolerance to environmental stress factors and winter hardiness obtained from rye (Tyrka and Chełkowski 2004;Pronyk and Mazza 2011;Mergoum et al 2019). All of those qualities make triticale a valuable and well-established worldwide crop which grain is used for animal food as well as human food consumption (Losert et al 2017;Ayalew et al 2018).…”

“…Triticale is also a valuable genetic bridge for transferring eligible genes among rye and wheat genetic pool using molecular breeding techniques (Tams et al 2004;Tyrka and Chełkowski 2004;Badea et al 2011). QTL mapping, MAS, genomic selection and next-generation sequencing (NGS) are widely used to improve crop species, especially wheat and rye; in contrast, molecular breeding in triticale is still limited (Jannink et al 2010;Tyrka et al 2018;Mergoum et al 2019). So far, a few research studies describe genetic maps of triticale and QTL analysis of mapping important traits in this cereal (Alheit et al 2011;Tyrka et al 2011Tyrka et al , 2015Tyrka et al , 2018Wen et al 2018).…”

The vitality and the development in the seedling stage is crucial in winter cereal’s life cycle, especially before and during winter. It has been reported that rapid seedling establishment and early growth may lead to higher crop yield. Localization of cereal genome regions is not often analysed in the seedling stage. The aim of this study was to identify winter triticale genome regions (QTL) associated with seedling leaves development. Based on ‘Hewo’ x ‘Magnat’ DH lines population genetic map composed of 3539 molecular markers assigned to 20 linkage groups with 4997.4 cM map length, in total 40 loci were identified by a composite interval mapping (CIM). Among them, 22 loci appeared in at least two experiments, were common for all analyzed traits as well as were identified on wheat chromosome 4B and on rye chromosomes 1R, 4R, 5R and 6R. Those loci explained up to 21.7% of phenotypic variation (Qwsl.hm.4R.2) and had LOD value up to 31.1 (Qlsl.hm.5R.1). The results of QTLs of seedling leaves development could be successively associated with QTLs of the freezing and fungal infection seedlings tolerance identified in this mapping population.

“…The tertiary pool of starch synthase gene allele diversity in wheat-related species and their hybrids has been studied insufficiently [33]. The studies of starch in triticale, and starch synthase variability in triticale, are ongoing [34][35][36]. Recently, complete sequences of the Wx gene in Taeniatherum and Hordeum chilense Roem.…”

Waxy Gene-Orthologs in Wheat × Thinopyrum Amphidiploids

Starch, as the main component of grain in cereals, serves as the major source of calories in staple food and as a raw material for industry. As the technological and digestive properties of starch depend on its content, the management of its components, amylose and amylopectin, is of great importance. The starch properties of wheat grain can be attuned using allelic variations of genes, including granule-bound starch synthase I (GBSS I), or Wx. The tertiary gene pool, including wheatgrass (Thinopyrum) species, provides a wide spectrum of genes-orthologs that can be used to increase the allelic diversity of wheat genes by wide hybridization. Octaploid partial wheat–wheatgrass hybrids (amphidiploids, WWGHs) combine the complete genome of bread wheat (BBAADD), and a mixed genome from the chromosomes of intermediate wheatgrass (Thinopyrum intermedium, genomic composition JrJrJvsJvsStSt) and tall wheatgrass (Th. ponticum, JJJJJJJsJsJsJs). Thus, WWGHs may carry Wx genes not only of wheat (Wx-B1, Wx-A1 and Wx-D1) but also of wheatgrass origin. We aimed to assess the level of amylose in starch and investigate the polymorphism of Wx genes in 12 accessions of WWGHs. Additionally, we characterized orthologous Wx genes in the genomes of wild wheat-related species involved in the development of the studied WWGHs, Th. intermedium and Th. ponticum, as well as in the putative donors of their subgenomes, bessarabian wheatgrass (Th. bessarabicum, JbJb) and bluebunch wheatgrass (Pseudoroegneria stipifolia, St1St1St2St2). Although no significant differences in amylose content were found between different WWGH accessions, SDS-PAGE demonstrated that at least two WWGHs have an additional band. We sequenced the Wx gene-orthologs in Th. bessarabicum, P. stipifolia, Th. intermedium and Th. ponticum, and developed a WXTH marker that can discriminate the Thinopyrum Wx gene in the wheat background, and localized it to the 7E chromosome in Th. elongatum. Using the WXTH marker we revealed the allelic polymorphism of the Thinopyrum Wx gene in the studied WWGHs. The applicability of Thinopyrum Wx genes in wheat breeding and their effect on starch quality are discussed.
