摘要：

A BC2 population of 353 plants segregating for the Ppd-HI photoperiod response gene was developed from a cross between the winter barley 'Igri' and the spring barley 'Triumph. Bulk segregant analysis identified six AFLP markers closely linked to the Ppd-H1 gene and three strongly amplified AFLP bands that mapped 0.8-cM distal, 0.6-cM proximal and 2.3-cm proximal to Ppd-H1 were cloned and sequenced. Southern-blot analysis showed that the cloned fragments were single-copy sequences in 'Igri', the variety from which they were derived. Two of the sequences were absent from 'Triumph' while the third detected a single-copy sequence. The cloned fragments were used to design specific sequence tagged site (STS) primer pairs to assist in the construction of a high-resolution map of the Ppd-H1 region.
