Identification of Microsatellite Markers Linked to Photoperiod Insensitive Gene Ppd-D1a in Wheat

  • 2

To facilitate breeding of lines with either the Ppd-D1a or ppd-d1a, we screened 342 F2 progenies from a cross between Laura (photoperiod insensitive, Ppd-D1a) spring wheat and SWP5304 (photoperiod sensitive, ppd-d1a) for their time to heading under 10 hour day length, and with a set of 37 microsatellite primers previously mapped to chromosome 2D. Bulk segregant analysis was used to identify four linked microsatellite loci. The Ppd-D1a locus was flanked by Xgwm484 with 13.7 cM distance and Xgwm455 with 27 cM. These markers may be useful in selection of the desired photoperiod sensitivity in segregating populations grown in Northern latitude.
