TDB1, total dry biomass before flowering (kg/hm²); TDB2, total dry biomass at maturity (kg/hm²); SN, spike number (104/hm²); SLN, spikelet number; NFS, number of fertile spikelets per spike; NIS, number of infertile spikelets per spike; GSRD, grain setting rate difference to control; TGW, thousand grain weight (g); GY, grain yield (kg/hm²); GYD, grain yield difference to control. The student's t-test was performed for statistical analysis, and different letters within a column indicate statistically significant differences between blocks at p < 0.01.
