Genotypes for the genes associated with responses to vernalization and photoperiod in the cultivars and lines under study

Cultivar or line	Vernalization and photoperiod genes
	VRNH1a	VRNH2b	VRNH3c	PPDH1d	PPDH2e
‘Plaisant’	vrnh1	VRNH2	vrnH3	PPDH1	ppdH2
SBCC106	VRNH1-6	VRNH2	vrnH3	PPDH1	PPDH2
SBCC058	VRNH1-4	VRNH2	vrnH3	PPDH1	PPDH2
‘Alexis’	VRNH1-3	vrnH2	vrnH3	ppdH1	PPDH2
‘Pané’	VRNH1-4	VRNH2	vrnH3	PPDH1	PPDH2
‘Beka’	VRNH1-1	vrnH2	vrnH3	ppdH1	PPDH2
‘Mogador’	vrnh1	VRNH2	vrnH3	ppdH1	ppdH2

^aAlleles based on the size of intron 1, in accordance with Hemming et al. (2009).

^bPresence/absence of HvZCCT, in accordance with Karsai et al. (2005).

^cAlleles based on two SNPs in intron 1, as reported by Yan et al. (2006).

^eAlleles based on SNP22 of Turner et al. (2005).

^eAlleles based on amplification of a 431 bp product using primers FT3.1F (5'-ATCCATTGGTTGTGTGGCTCA-3') and FT3.2R (5'-ATCTGTCACCAACCTGCACA-3'), which amplify the entire region from exons 1 to 2 of the HvFT3 gene (‘Alexis’, SBCC058, SBCC106, ‘Pané’, and ‘Beka’). These primers give a null allele for ‘Plaisant’ and ‘Mogador’. The allele from ‘Plaisant’ (ppdH2) was amplified using the F4/R1 primers reported by Kikuchi et al. (2009). HvFT3 was localized on the long arm of chromosome 1H in the ‘Beka’בMogador’ mapping population (Supplementary Fig. S1 at JXB online), which matches the location of a QTL for response to a short photoperiod (Supplementary Fig. S2).
