PRAGUE, Oct. 3 (Xinhua) -- An international team including Czech scientists has created a map of the largest wheat chromosome which is the fundamental step towards understanding the genome of the second most produced food among the cereal crops, the Czech news agency CTK said on Friday.

    The understanding of the wheat genome will facilitate the cultivation of more high-yielding and disease-resistant wheat varieties in the future, according to the Czech Academy of Sciences Press Department.

    A unique technology for sorting of chromosomes invented by researchers from the Academy of Sciences Institute of Experimental Botany based in Olomouc, east of the Czech Republic, is the key for the solution, the report said.

    The team published its invention in the prestigious journal Science, the Academy of Sciences said.

    Researchers from France, the Czech Republic and four other countries used the method invented by Czech scientists for the creating of the physical map of the 3B chromosome, which is necessary for the detailed understanding of the wheat genome, CTK said.

    At present, the scientists are creating the physical maps of other three chromosomes. The completion of the map of the entire wheat genome can be expected within three to five years, it added.
