Estimated additive (A) and additive×environment (AE) interactions of QTLs for flowering time in three photoperiod environments.

<p>Note:</p>a<p>: Additive effect: positive values indicated that Huangzao4 carries the allele for an increase in the trait, while negative values indicate that CML288 contributed the allele for an increase in the trait value.</p>b<p>, additive×environment (AE) interactions effect:E1, Sanya; E2, Henan; E3, Beijing.</p>c<p>, Contribution explained by putative main-effect QTL.</p>d<p>, Contribution explained by additive×environment (AE) interactions.
