aFor each of the genotype, medium, and genotype × medium interaction factors, mean values within a column separated by different letters are significantly different (𝑃<0.05) according to Duncan’s multiple range test.
^bNot determined.
c***, **, *, and ns indicate being significant, at 𝑃<0.001, 𝑃<0.01, and 𝑃<0.05, and nonsignificant, respectively.
