All lines carry Vrn-H2 (winter allele), Ppd-H1(early-flowering allele), and Ppd-H2 (early-flowering allele) in common. bAll the dominant alleles for Vrn-H1 are identical with HvVRN1-10 (Hemming et al., 2009). They were derived from the var. Indo Omugi except for the allele in NIL (Vrn-H1, Vrn-H3) that was derived from the Japanese var. Marumi 16. cH and N indicate the alleles from HK2 and NIL (Vrn-H1), respectively. dApril 1 = 1. Values with different letters (p, q, r, s, or t) indicate significant difference (P < 0.01) by the Tukey test.
