Abstract

Greenhouse screening of 17,914 accessions of rice, Oryza sativa L., from 62 countries identified 115 accessions from 10 countries having resistant or moderately resistant reactions to Cnaphalocrocis medinalis Guenée. Of 264 wild rices (Oryza spp.) screened, 10 (3.7%) were resistant. Several breeding lines having “Ptb33” and “W1263” as donor parents were moderately resistant. All of the resistant accessions are from regions where C. medinalis is an important pest, except for one accession from Italy, which is beyond the range of C. medinalis distribution.
