Haploid induction through chromosome elimination by remote hybridization has been a practical technique in wheat breeding using double haploid.Tagging of the specific genome and chromosome(s) of wheat and its relatives triggering chromosome elimination was carried out in wheat x Imperata cylindrica system. The mechanism of haploid induction was investigated at molecular-cytogenetic level. The 2D and 7D chromosomes of Aegilops tauschii are deeply involved in chromosome elimination and the subsequent growth of a haploid embryo. The results of research contribute to wheat improvement by the double haploid breeding.
