Disclosed is a method of constructing a wild-species genomic library of chromosome fragments incorporated in a crop-species genome. First a number of , transformants for donor and recipient plant species is produced carrying the , DNA constructs necessary for the exchange of chromosomal fragments mediated by site-specific recombination. The donor and recipient are chosen such that upon sexual cross or somatic cell fusion they produce unstable progeny or , demonstrate preferential segregation or sorting out. Second the crossing , between donor and recipient species and formation of chromosomal recombinants of donor and recipient plant species is induced. Third taking advantage of , the …
