Breeding of T. aestivum-Ag. Intermedium translocation lines with T. timopheevii cytoplasm and characterization by EISH

摘要

A male-sterile T. aestivum-Ag. Intermedium partial amphiploid with cytoplasm of T. timopheevii as a female parent was crossed to common wheat. The hybrid was backcrossed to the male parent several times continually and self-crossed at last. Two stable lines with common wheat phenotype, H96269-2 and H96278, have been obtained. The chromosome numbers of the two lines are all 2n = 42 in somatic cells.
