title: [The chromosome-specific PCR marker's screening and identification of barley 6H chromosome].
abstract: Two barley 6H chromosome specific RAPD markers were obtained by screening DNA of barley Hordeum vulgare (Betzes) and wheat-barley 6H addition line with 200 primers, then the RAPD markers were changed into specific PCR markers. Checking different plant materials by the PCR markers, it revealed that there was a specific band in those materials containing 6H chromosome such as Betzes, Igri, CS6H, and there was no specific band if the material did not contain 6H chromosome, such as Triticum aestivum, Secale cereale, Agropyron intermedium, Haynaldia villosa, Thinopyrum elongatum. Therefore, those PCR markers specific to chromosome 6H of barley are established. Southern hybridization indicated that the two cloned DNA fragments belong to barley genomic specific high-copy repeat sequence and low-copy sequence in wheat and barley genomes respectively.
