Abstract: In this paper, the synthetic procedure of octoploid Trititrigia from t.aestivum×Th.intermedium and hexaploid Trititrigia from T.durum×Th.intermedium were revealed by systematic cytogenetic studies.We detected the chromosome constitution of Trititrigia by using fluorescence in situ hybridization.The results indicated that the production of Trititrigia is related to the unreduced gametes and the pivotal genomes of the BC1F1 plants.

Key words: Thinopyrum intermedium, Unreduced gamete, Trititrigia
