Additional file 1: Fig. S1. The phenotype of theB73 and Abe2 inbred lines at the flowering stage inHainan. Thered arrows point to the tassel and ear of abe2, respectively. Scale bar= 20 cm. Fig. S2. Correlation coefficients of floweringtime-related traits in different field trials. The heat map representsthe correlation strength (r) between the paired traits.Significance: *, P ≤ 0.05; **, P ≤ 0.01. DTH, days to heading; DTS,days to silking; DTA, days to anthesis; LA, number of leaves above the primaryear; LB, number of leaves below the primary ear; TLN, total leaf number. Hn andHf represent Hainan and Hefei, respectively, which are two locations in Chinawith distinct climates. Fig. S3. Correlation between the genetic and physicallocations of the polymorphic specific-locus amplified fragment markers.
