a
Data are presented as means with sd. Lowercase letters indicate connecting letter report as determined by ANOVA with posthoc analysis using the Holm-Sidak algorithm with P < 0.05.
b
Number of plants with tassel seeds or anthers in ear florets, with the percentage of plants in parentheses. Lowercase letters indicate connecting letter report as determined by Fisher’s exact test with P < 0.01.
