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.

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

Varma et al. (2025) studied this question.
