Fig 1. ZCN8 contributes to flowering time variability in temperate maize lines.

(A) Relationship between genotypic values for anthesis in field (2015–2016) and platform (2014) experiments. (B) Anthesis time plotted against ZCN8 expression after the floral transition (platform experiment in 2014). (C) Relationship between anthesis measured in the field (2015–2016) and ZCN8 expression in the platform experiment (2014). In (A), (B) and (C) n = 313 lines. Genotypic values are BLUEs. Anthesis time expressed in equivalent days at 20°C after germination. The red triangle represents genotypic values for the reference line B73. Correlation coefficients are displayed together with their significance (*** p < 10−⁴).
