Allelic diversity of a panel ofAegilops muticaBoiss (Amblyopyrym muticum(Boiss.) Eig) from Turkey

Abstract

The members of the Aegilops genus serve as a vast pool of allele discovery for wheat improvement in abiotic and biotic stress responses. Aegilops mutica Boiss (Amblyopyrym muticum (Boiss) Eig) is an unexplored candidate with significant potential. Even though it has been used in cytogenetics applications within the last century, natural population diversity and allele discovery have been neglected. As an endemic species for Anatolia and the lower Caucasian region, it has an unexplored population structure. Here, seventy-five genotypes from five different newly collected populations from central Anatolia were evaluated with 29 polymorphic SSR loci. Significant diversity within (83%) and between (17%) the populations was obtained. Three of the populations were clearly separated, while two had some level of the mixture. Relatively easy cross-species hybridization and introgressions make Ae. mutica a good candidate for novel allele discovery and pre-breeding. Here, for the first time, representative natural populations of Ae. mutica were compared and population structures were revealed with SSR markers which may clear the misty vision that geneticists might have regarding Ae. mutica. This could be exploited in genetic resource conservation and breeding programs and maybe a point for further studies.

Assessment of genetic relation for Aegilops and Triticum possessing different genome-bearing species using start codon targeted marker

“…They are potential sources of genetic variation and numerous unique alleles for breeding purposes of T. aestivum and can serve as a secondary gene pool of this species (Ghobadi et al 2021;Ivanizs et al 2019). The introduction of genes from these genera can contribute to improving quality (Ahmadi and Pour-Aboughadareh 2015), yield performance (Mahjoub et al 2016;Schneider et al 2008) and resistance to biotic (Alsaleh et al 2022) and abiotic stresses (Suneja et al 2019;Trono and Pecchioni 2022).…”
