Frequency distribution of the BPH resistance evaluation of F2:3 lines derived from the cross KWQZ/IR64. a, Seedlings survival rate. Three-week-old seedlings were treated with five to six BPHs per plant for 20 days. The survival rates of the parents IR64 and KWQZ were 67 and 18%, respectively. A lower survival rate indicates more susceptible. b, BPH resistance scores. Three-leaf seedlings were treated with eight BPHs per plant for 9–10 days. The average resistance scores of the parents IR64 and KWQZ were 5.6 and 8.7, respectively. A lower score indicates higher resistance
