Abstract Purpose To transfer the 2S chromosomal fragment(s) of Aegilops kotschyi (2Sk) into the bread wheat genome which could lead to the biofortification of wheat with high grain iron and zinc content. Materials and methods Wheat-Ae. kotschyi 2A/2Sk substitution lines with high grain iron and zinc content were used to transfer the gene/loci for high grain Fe and Zn content into wheat using seed irradiation approach. Results Bread wheat plants derived from 40 krad-irradiated seeds showed the… 
Precise transfers of genes for high grain iron and zinc from wheat-Aegilops substitution lines into wheat through pollen irradiation
TLDR
The pollen radiation hybrids of both the groups 2 and 7 chromosomes showed more than 30% increase in grain Fe and Zn content with improved yield than the elite wheat cultivar PBW343 LrP indicating small and compensating transfers of metal homeostasis genes of Aegilops into wheat.
Induced Homoeologous Pairing for Transfer of Useful Variability for High Grain Fe and Zn from Aegilops kotschyi into Wheat
TLDR
Induced homoeologous pairing in the absence of 5B was found to be an effective approach for transfer of useful variability for enhanced grain Fe and Zn content for biofortification of wheat for high grain micronutrient content.
Uptake, distribution, and remobilization of iron and zinc among various tissues of wheat–Aegilops substitution lines at different growth stages
TLDR
The micronutrients accumulation status is followed by wheat–Aegilops substitution lines and is the least in wheat cultivars indicating that the donor Aegilops species and their substituted chromosomes possess genes for higher iron and zinc uptake and mobilization.
Genotypic and ecological variability of zinc content in the grain of spring bread wheat varieties in the international nursery KASIB
TLDR
The analysis of variance showed that the most favorable environmental conditions for accumulation of zinc in wheat grain were observed in the Omsk region, and the main contribution into the general phenotypic variation of the studied trait was made by the factors ‘location’ and ‘genotype’.
Transfer of HMW glutenin subunits from Aegilops kotschyi to wheat through radiation hybridization
TLDR
The transfer/substitution of alien HMW-GS for Glu-1A and or GLU-1B loci only can lead to improved bread making quality of wheat.
Potential of Aegilops sp. for Improvement of Grain Processing and Nutritional Quality in Wheat (Triticum aestivum)
TLDR
The potential of Aegilops for improvement of processing and nutritional traits in wheat is reviewed and information available on exploration of nutritional and processing quality related traits in Aegilop section is tried to compile.
Transferability and Polymorphism Between Group 7 Chromosome Specific Simple Sequence Repeat (SSR) Markers of Bread Wheat and Its Related Non-Progenitor Aegilops Species
TLDR
The study revealed 77% transferability of group 7-specific SSR markers of bread wheat to 7U/7S chromosomes of Aegilops species and more than 80% of the 7D specific markers were found to be transferable with a high level of polymorphism.
Grain mineral composition of Argentinean-adapted wheat cultivars: a case study
Abstract. Improvement of the nutritional quality of wheat (Triticum aestivum L.) has been quite challenging, due, in part, to the limited variation found in modern cultivars and the strong effect

Substitutions of 2S and 7U chromosomes of Aegilops kotschyi in wheat enhance grain iron and zinc concentration
TLDR
GISH and FISH analysis of some derivatives confirmed the substitution of chromosomes 2S and 7U for their homoeologues of the A genome, suggesting that some of the genes controlling high grain micronutrient content in the Ae.
Introgression of group 4 and 7 chromosomes of Ae. peregrina in wheat enhances grain iron and zinc density
TLDR
The development of derivatives with significantly higher grain micronutrients, high thousand-grain weight and harvest index suggests that the enhanced micronUTrient concentration is due to the distinct genetic system of Ae.
The use of irradiated pollen for differential gene transfer in wheat (Triticum aestivum)
TLDR
Results are interpreted as showing that irradiation damage to the paternal genome in M1 plants results in the differential transmission of maternal alleles.
Radiation Hybrid Mapping of the Species Cytoplasm-Specific (scsae) Gene in Wheat
TLDR
This constitutes the first report of using RH mapping to localize a gene in wheat and illustrates that this approach is feasible in a species with a large complex genome.
Biofortification of wheat grain with iron and zinc: integrating novel genomic resources and knowledge from model crops
TLDR
How the latest resources developed in wheat, including sequenced genomes and mutant populations, can be exploited for biofortification is explored, which requires developing new varieties of wheat with inherently higher iron and zinc content in their grains.
Molecular cytogenetic analysis of Triticum aestivum-Leymus racemosus reciprocal chromosomal translocation T7DS·5LrL/T5LrS·7DL
TLDR
In the self-fertilized progenies of the heterozygous reciprocal translocation, a line with the homozygous translocation line with a pair of translocation chromosome T7DS·5LrL was identified, highly resistant to wheat scab and can be used as a potential and new source in wheat improvement for scab resistance.

It is demonstrated that integrated use of cytogenetic stocks and molecular resources can enhance the efficiency and precision of homoeologus-based chromosome engineering.
Zinc and Iron Concentrations in Seeds of Wild, Primitive, and Modern Wheats
TLDR
It is demonstrated that the genetic variation in the concentrations of zinc and iron in cultivated modern tetraploid and hexaploid wheats is extremely low when compared with the variation found in wild diploids and tetra ploids, which suggests that wild wheats can be considered a major source of genetic diversity for increasing zinc andIron density in the seeds of modern wheats.
