Linkage Relationships in Wild Emmer Wheat, TRITICUM DICOCCOIDES.
The linkage relationships in wild emmer wheat, Triticum dicoccoides , between nine enzymatic loci (Mdh-1, Ipo, beta-Glu, Pept-1, Pept-3, Est-5, Est-1, 6Pgdh-2 and Hk) and a coleoptile pigment locus (Rc) were investigated. Chromosome locations of genes were inferred from analysis of ditelocentric lines of Triticum aestivum, cultivar Chinese Spring. The loci Mdh-B1 and Hk are linked (lambda = 0.1...
متن کاملAncestral QTL Alleles from Wild Emmer Wheat Enhance Root Development under Drought in Modern Wheat
A near-isogenic line (NIL-7A-B-2), introgressed with a quantitative trait locus (QTL) on chromosome 7AS from wild emmer wheat (Triticum turgidum ssp. dicoccoides) into the background of bread wheat (T. aestivum L.) cv. BarNir, was recently developed and studied in our lab. NIL-7A-B-2 exhibited better productivity and photosynthetic capacity than its recurrent parent across a range of environmen...
متن کاملAncestral QTL Alleles from Wild Emmer Wheat Improve Drought Resistance and Productivity in Modern Wheat Cultivars
Wild emmer wheat (Triticum turgidum ssp. dicoccoides) is considered a promising source for improving stress resistances in domesticated wheat. Here we explored the potential of selected quantitative trait loci (QTLs) from wild emmer wheat, introgressed via marker-assisted selection, to enhance drought resistance in elite durum (T. turgidum ssp. durum) and bread (T. aestivum) wheat cultivars. Th...
متن کاملWild emmer wheat, Triticum dicoccoides, occupies a pivotal position in wheat domestication process
Domestication of plants and animals is the major factor underlying human civilization. Cultivated wheats refer mainly to two types: the hexaploid bread wheat (Triticum aestivum) accounting for about 95% of world wheat production, and the tetraploid durum wheat (T. durum) accounting for the other 5%. T. aestivum derived from a cross between domesticated emmer T. dicoccum and the goat grass Aegil...
متن کاملQuantifying rooting at depth in a wheat doubled haploid population with introgression from wild emmer
Background and Aims The genetic basis of increased rooting below the plough layer, post-anthesis in the field, of an elite wheat line (Triticum aestivum 'Shamrock') with recent introgression from wild emmer (T. dicoccoides), is investigated. Shamrock has a non-glaucous canopy phenotype mapped to the short arm of chromosome 2B (2BS), derived from the wild emmer. A secondary aim was to determine ...
