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.
