Here, we report the complete plastomes of two polyploid wheat species, <i>Triticum sphaerococcum</i> (AABBDD) and <i>Triticum turgidum</i> subsp. <i>durum</i> (AABB), and compare them with 19 available and complete <i>Triticum</i> plastomes to create the first map of genomic structural variation. Both <i>T. sphaerococcum</i> and <i>T. turgidum</i> subsp. <i>durum</i> plastomes were found to have a quadripartite structure, with plastome lengths of 134,531 bp and 134,015 bp, respectively.
