Comment
A photoperiod response gene that affects flowering time under long days (13h or 16h light) but has little effect under short days (10h). In the field it is the major determinant of flowering time variation in the doubled haploid population. Its map location suggests it may be equivalent to the Ppd series of photoperiod response genes in wheat.
