BLS resistance test
Pathogen inoculation was conducted at the tillering stage of rice (30 days) with a virulent Xoc strain, GX01, using the pricking inoculation approach. Three leaves from each plant and five plants from each line were inoculated. The longitudinal length of the lesion on each leaf was measured 18 days after inoculation. The average lesion length of the three leaves was calculated for each plant, and the average lesion length of the four plants was calculated to indicate the BLS resistance of each line.
