Summary
Hybrids naturally arising between Triticum species and between Triticum species and species of Secale and Aegilops are found in wheat fields in Transcaucasia. This continuous exchange of genetic material will yield new genotypes which may be useful in breeding.
This active source of the origination of new botanical (sub)varieties results in a great diversity of species and varieties which led Vavilov to conclude that Transcaucasia is centre of origin of several Triticum species and varieties.
