Phenotypic effects of Am genomes in nascent synthetic hexaploids derived from interspecific crosses between durum and wild einkorn wheat.

ABSTRACT: Allopolyploid speciation is a major evolutionary process in wheat (Triticum spp.) and the related Aegilops species. The generation of synthetic polyploids by interspecific crosses artificially reproduces the allopolyploidization of wheat and its relatives. These synthetic polyploids allow breeders to introduce agriculturally important traits into durum and common wheat cultivars. This study aimed to evaluate the genetic and phenotypic diversity in wild einkorn Triticum monococcum ssp. aegilopoides (Link) Thell., to generate a set of synthetic hexaploid lines containing the various Am genomes from wild einkorn, and to reveal their trait characteristics. We examined the genetic diversity of 43 wild einkorn accessions using simple sequence repeat markers covering all the chromosomes and revea
