a
H and N indicate the alleles from HK2 and NIL (Vrn-H1), respectively. bRecessive allele for Ppd-H1 confers late flowering under long photoperiod. cDominant allele for Ppd-H2 confers early flowering under short photoperiod. dDominant allele for Vrn-H1 (identical with HvVRN1-10 in Hemming et al. [2009]), recessive allele for Vrn-H2, and dominant allele for Vrn-H3 confer spring growth habit.
