Abstract:

The rice blast fungus, Pyricularia grisea, is known for its pathogenic variability. The need for a set of differential rice lines suitable for pathotyping isolates of the pathogen has long been recognized. For this reason, two sets of near-isogenic lines (NILs) carrying individual blast resistance genes have been developed over the past few years. We demonstrate here the utility of using both sets of lines together for pathotypic analysis of Philippine lineages of P. grisea.
