  1. Note: Pollen fertility and spikelet fertility were shown as mean ± SD. a Duncan’s multiple comparison test was conducted for pollen fertility and spikelet fertility. Numbers followed by different letters in each row represented statistically significant difference at P = 0.01, while numbers with the same letter indicated no significant difference at P = 0.05
