Maternal and xenia effects on the weight of hybrid seeds (thousand seed weight).

a: “L” denotes large-seed lines; “S” denotes small-seed lines. b: Rows followed by the same capital letter indicate no significance at the 0.01 probability level based on a Duncan test; rows followed by the same lowercase letter indicate no significance at the 0.05 probability level based on a Duncan test. c: The large estimated maternal effects (> 1) were primarily due to the existence of the ultra-high and ultra-low seed weight parental individuals.
