^†Broad-sense heritability was quantified using $\frac{{\sigma }_{G^2}}{{\sigma }_G^2+\frac{{\sigma }_e^2}{r}}$, in which ${\sigma }_G^2$ is the genetic variance, ${\sigma }_e^2$ is the residual variance, and r is the number of replicates. ‡ Adventitious root was observed only in flooded condition.
