Comparisons of the plant yield and agronomic traits of AP3, AP8 and AP9 in indica varieties. a Comparison of the effective panicles per plant between AP3, AP8 and AP9. b Comparison of the seed setting rate among AP3, AP8 and AP9. c Comparison of the spikelets per panicle among AP3, AP8 and AP9. d Comparison of the thousand-grain weight among AP3, AP8 and AP9. e Comparison of the yield per plant among AP3, AP8 and AP9. All data are presented as the means ± SD. The letters above the bars are ranked by Duncan test at P < 0.05; the same letters indicate no significant differences, and different letters indicate significant differences
