Article Information The aim of the study was to investigate the extent of the genetic diversity among gene bank accessions of Ethiopian tetraploid wheat (Triticum turgidum L.) landraces using microsatellite markers, qualitative and quantitative data. Thirty five accessions of Ethiopian tetraploid wheat (T. turgidum L.) landraces were grown in the greenhouse at IFA Tulln, Austria during spring 2...

15 The aim of the study was to investigate the extent of the genetic diversity among 16 genebank accessions of Ethiopian tetraploid wheat (Triticum turgidum L.) using 17 microsatellite markers, qualitative and quantitative data. Thirty-five accessions of 18 Ethiopian tetraploid wheat (T. turgidum L.) landraces were grown in the greenhouse 19 at IFA Tulln, Austria during spring 2009 for DNA extr...

Expression of resistance to Meloidogyne incognita and M. javanica from Aegilops squarrosa was studied in a synthetic allohexaploid produced from Triticum turgidum var. durum cv. Produra and Ae. squarrosa G 3489. The reproductive rate of different races of M. incognita and M. javanica, expressed in eggs per gram of fresh root, was low (P < 0.05) on the synthetic allohexaploid and the resistant p...

The data presented are related to the research article entitled "Comparison of the dietary fibre composition of old and modern durum wheat (Triticum turgidum spp. durum) genotypes" (De Santis et al., 2018) [1]. This article provides details of the structures of the major dietary fibre components, arabinoxylan and β-glucan, in semolina and wholemeal flour of old and modern Italian durum wheat ge...

Nascent allohexaploid wheat may represent the initial genetic state of common wheat (Triticum aestivum), which arose as a hybrid between Triticum turgidum (AABB) and Aegilops tauschii (DD) and by chromosome doubling and outcompeted its parents in growth vigor and adaptability. To better understand the molecular basis for this success, we performed mRNA and small RNA transcriptome analyses in na...

Wild emmer wheat, Triticum turgidum ssp. dicoccoides is the wild relative of Triticum turgidum, the progenitor of durum and bread wheat, and maintains a rich allelic diversity among its wild populations. The lack of adequate genetic and genomic resources, however, restricts its exploitation in wheat improvement. Here, we report next-generation sequencing of the flow-sorted chromosome 5B of T. d...

Polyploidy is known to induce numerous genetic and epigenetic changes but little is known about their physiological bases. In wheat, grain texture is mainly determined by the Hardness (Ha) locus consisting of genes Puroindoline a (Pina) and b (Pinb). These genes are conserved in diploid progenitors but were deleted from the A and B genomes of tetraploid Triticum turgidum (AB). We now report the...
