description The possible origin of four cultivated species of the genus <i>Avena</i> of different ploidy and different subgenome composition (<i>A. strigosa</i>, <i>A. abyssinica</i>, <i>A. byzantina</i>, and <i>A. sativa</i>) from possible wild species was investigated. The region of the internal transcribed spacer ITS1 and the 5.8S rRNA gene in the cultivated species was studied with next-generation sequencing (NGS), and the patterns of occurrence and distribution of the ribotypes were compared among them and with those of the wild species. According to these data diploid, <i>A. strigosa</i> is more closely related to the diploid <i>A. hirtula</i> than to polyploid oats, and it could have evolved independently of polyploid cultivated species. The tetraploid <i>Avena abyssinica</i> could be a cultivated derivative of <i>A. vaviloviana</i>. Two hexaploid cultivated species, <i>A. byzantina</i> and <i>A. sativa</i>, could have a different origin; <i>A. sativa</i> could be the cultivated form of <i>A. fatua</i>, whereas <i>A. byzantina</i> could originate independently. It was found that the oat species with the A and C subgenomes, even with strong morphological and karyological differences, could intercross and pass the further stages of introgression producing a new stable combination of genomes. Our data show that almost all species of <i>Avena</i> could form an introgressive interspecies complex.
