Abstract

In this study, the intergeneric hybrids F, F, BCF, BCF, and BCF from and crosses were produced to study their chromosome pairing behavior. The average chromosome configuration of the two F hybrids agreed with the theoretical chromosome configuration of 21I+7II, indicating that the genomic constitution of this F hybrid was ABDStStEEE. Compared with the BCF generation, the BCF generation showed a rapid decrease in the number of chromosomes and the BCF generation showed a more extensive distribution of chromosomes. In addition, pairing between wheat and chromosomes was detected in each of the wheat hybrid progenies, albeit rarely. Our results demonstrated that genomic hybridization (GISH) using an genomic DNA probe offers a reliable approach for characterizing chromosome pairing in wheat and hybrid progenies.
