Overview

Phenotypic screening shows two rice genotypes exhibit strong resistance to the brown planthopper, suggesting new breeding avenues.

Key Points

  • Two rice genotypes showed consistent resistance to the brown planthopper over two years.
  • Genome wide association studies identified significant SNPs linked to known BPH resistance genes.
  • Lower honey dew excretion and nymphal survival rates indicated effective resistance mechanisms in selected genotypes.
  • Candidate gene analysis revealed that quantitative trait nucleotides contribute significantly to brown planthopper resistance.
