摘要
The translocation frequency up to 3.7% has been obtained by crossing a Triticum-Thinopyrum substitution with a Triticum-Hayna/dia substitution. The pattern of translocations includes not only wheat-alien Robertson translocations but also inserting translocations involving Thinopyrum chromatin and Haynaldia 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.
