The use of chromosome substitutions and translocations in the breeding of triticale, wheat and rye

摘要

In triticale, wheat and rye chromosomes conjugate very rarely in meiosis. However, substitutions and translocations within a homoeologic group are quite frequent. Thereby, there is an exchange of arms between wheat and rye chromosomes. These translocated chromosomes contain genes of two different species. With the help of backcrossing of triticale with initial forms, these chromosomes were used to create new forms of wheat and rye.
