Some chromosomes derived from genus Aegilops have complete or incomplete gametocidal effects whenever the chromosomes are attached to common wheat in different genetic background with monosomic form, which might cause chromosome structural aberrations, such as translation, deletion or other effects, to facilitate alien genes of interest introgressing into wheat genome. Moreover, it is also informative and helpful to construct deletion maps as well as physical maps［1］. This paper reviewed the progress of studies on constructing deletion maps of wheat, rye and barley by means of the strategy of gametocidal chromosome
