In vitro variation of B chromosomes was studied by examining the callus cells derived from the immature embryos from a cross of Chinese Spring wheat （Triticum aestivum L.） and Fin 7416 rye （secale cereale L.） carrying two B chromosomes. In 40-d-old callus cells, the numbers of B chromosomes ranged from one to four in 65.6% of the cells observed. The distribution of B chromosome numbers was associated with the ploidy levels of the normal chromosomes （A chromosomes）. The frequency of the cells with high numbers of B chromosomes （i.e., three or four B chromosomes） in the amphiploid cells with 56 A chromosomes was greater than those in the haploid cells with 28 A chromosomes. Although structural changes in the rye A chromosomes were observed, cytological observation and genomic in situ hybridization demonstrated that the rye B chromosomes were conserved in morphological appearance following tissue culture.

The genomic composition of 1911289, a wheat ( Tritium aestivum L.) maintainer of K-CMS, was examined by several methods, such as genomic in situ hybridization (GISH), biochemical marking, and DNA molecular marking. The results got by GISH and PCR amplification of dispersed rye-specific repetitive DNA sequence suggested that the alien chromatin in T911289 derived from rye. Specifically PCR amplification of the rye-specific microsatellite primers (SCM9) and seed storage protein analysis indicated that the alien chromatin in T911289 had developed from the short arm of 1R chromosome of rye (1RS). PCR amplification by using microsatellite primers locating on 1BS and seed storage protein analysis also revealed that 1911289 had lost the arm of 1BS or a small distal segment of it. We conclude that T911289 is a heterogeneous population which displays two distinct different types of translocation, i.e. the Robertsonian translocation and small segment translocation. The Robertsonian translocation type observed in our study is different from the 1BL/1RS translocation which is widely used in wheat production; it may be a novel and complex translocation form. Though the linkage between the desirable agronomic traits and the deleterious genes expressed as sticky dough has not got broken in T911289, the recovery of small segment translocation will still benefit the genetic study of wheat and rye.
