Abstract: Key message One hundred and thirty four introgressions from Thinopyrum elongatum have been transferred into a wheat background and were characterised using 263 SNP markers. Abstract Species within the genus Thinopyrum have been shown to carry genetic variation for a very wide range of traits including biotic and abiotic stresses and quality. Research has shown that one of the species within this genus, Th. elongatum, has a close relationship with the genomes of wheat making it a highly suitable candidate to ex… Show more

“…Discovery of the Ph1 locus led to the possibility of recombining non-homologous genomes with those of wheat. The same approach is now being followed in many other cereals [143,[185][186][187] and has been extended to include a wider range of CWR in wheat [188]. Genomic analyses can reveal the translocations and rearrangements that have been introduced, allowing for more structured and efficient screening of the huge array of novel recombinations that can be generated.…”

“…The use of the new technologies at the Nottingham BBSRC Wheat Research Centre (WRC) has allowed the transfer of hundreds of introgressions from a variety of wild relatives into wheat, e.g., Amblyopyrum muticum ( King et al, 2017 ), Thinopyrum bessarabicum ( Grewal et al, 2018b ), Ae. speltoides ( King et al, 2018 ), T. urartu ( Grewal et al, 2018a ), Triticum timopheevii ( Devi et al, 2019 ), Thinopyrum elongatum ( Baker et al, 2020 ), and Aegilops caudata ( Grewal et al, 2020b ). However, without identifying what genetic variation is carried by the introgressions, the lines produced will remain quite simply as ‘seeds in a packet’ of unknown agronomic potential.…”

“…Genotyping of introgression lines is more efficient when using wild-relative genomespecific SNPs. The Axiom ® Wheat-Relative Genotyping SNP Array was developed (King et al 2017) and used to detect introgressions from various wild species in a wheat background (Grewal et al 2018a;Grewal et al 2018b;King et al 2018;Cseh et al 2019a;Devi et al 2019;Baker et al 2020). Even though these genotyping arrays can be ultrahigh-throughput and efficient, these SNPs cannot distinguish between homozygous and heterozygous individuals which limits their widespread use in crop breeding.…”

“…tauschii. Many studies have revealed the existence of homoeology between the Thinopyrum genome and the wheat genome (Grewal et al 2018;Cseh et al 2019;Baker et al 2020;Wang et al 2020b). At the same time, several researchers have started to develop useful markers by comparative genomic analysis.…”

“…intermedium were probably derived from P. spicata [51], whereas it has been still unde ned that whether the St genome is one of the sets of chromosomes of Th. ponticum [11,52]. According to molecular cytogenetic identi cation results, ES-23 and ES-9 (group 1) contained the same genome composition of 12A + 14B + 14D + 2(2St), while ES-24 and ES-10 (group 2) were for the same genome composition of 14A + 14B + 12D + 2(3St).…”
