Production of translocation by crossing two different alien substitutions in wheat

The translocation frequency up to 3.7% has been obtained by crossing aTriticum-Thinopyrum substitution with aTriticum-Haynaldia substitution. The pattern of translocations includes not only wheat-alien Robertson translocations but also inserting translocations involvingThinopyrum chromatin andHaynaldia chromatin. The result indicates that it may be a new method of producing translocations to make two different wheat-alien substitution cross with each other.
