The major physiological determinants of wheat ( Triticum aestivum  L.) phenology in a given area are a response to vernalization temperature and day length, which are at least in part, regulated by the allelic variation at the vernalization ( VRN ) and photoperiod ( PPD ) loci, respectively. Characterization of the existing genetic variation for plant phenology in winter wheat can assist breeding programs improve adaptation to local environments and to optimize wheat phenology for the changing climate. The objectives of this research were to characterize the allelic variation at the major  VRN  and  PPD  loci in a diverse panel of high latitude winter wheat genotypes (n = 203) and to associate the allelic variation with phenologic, agronomic and adaptation traits. The panel was genotyped using allele-specific markers at vernalization ( VRN-A1 ,  VRN-B1 ,  VRN-D1  and  VRN-B3 ) and photoperiod ( PPD-A1 ,  PPD-B1 , and  PPD-D1 ) loci and phenotyped for agronomically-important traits. Though photoperiod sensitivity was more prevalent, most of the variation in the phenology of the winter wheat panel was explained by allelic variation at  PPD-D1 ,  PPD-A1 , and the interaction between these loci. While a typical high latitude winter wheat genotype is one that carries winter alleles at all major  VRN  loci and photoperiod sensitive alleles at the major  PPD  loci, in lower latitudes where winters are milder, the presence of one or two photoperiod insensitive alleles seems to contribute to higher yield and wider adaptation.
