Overview

Genetic analysis identifies novel resistant rice genotypes to brown planthopper, highlighting implications for pest management.

Key Points

  • This research aims to confirm resistance to brown planthopper in indica rice using genomic markers.
  • Evaluated 90 rice germplasms over two years for pest resistance.
  • Conducted phenotypic assessments for damage and survival rates against Nilaparvata lugens.
  • Performed genetic analysis and assessed genetic diversity among rice genotypes.
  • Identified one genotype with high resistance and four with moderate resistance to brown planthopper.
  • Genetic analysis revealed significant diversity and polymorphic information linked to 28 genes and 9 QTLs.
  • Seven markers associated with resistance were identified using various models.
