The response level had been divided into 0–9: 0, no lesion & no disease symptom; 1, small brown specks of pin point size, no spores; 2, small roundish to slightly elongated brown spots, necrotin gray spots; 3, lesion type is the same as in 2, but significant number of lesion are on the upper leaves; 4, typical susceptible blast lesions, infecting less than 2% of the leaf area; 5, typical susceptible blast lesions, infecting 2–10% of the leaf area; 6, typical susceptible blast lesions, infecting 11–25% of the leaf area; 7, typical susceptible blast lesions, infecting 26–50% of the leaf areas; 8, typical susceptible blast lesions, infecting 51–75% of the leaf areas; 9, typical susceptible blast lesions, infecting more than 75% of the leaf area, almost withered (from rice blast resistance screening).

All data had collected on 2018 except Dandong data had been collected on 2019.

Data had not been collected.
