Grain weight (A), grain filling rate (B), starch content (C), and sucrose content (D) of superior (SS) and inferior spikelets (IS) in NIL-GNP1TQ and Lemont during grain-filling period. The *, ** indicate significant difference between NIL-GNP1TQ and Lemont at P < 0.05 and P < 0.01, respectively. Error bars indicate standard error (n = 3).
