Substitution mapping and characterization of brown planthopper resistance genes from traditional rice cultivar 'Rathu Heenati' ( L.).

The brown planthopper (BPH; Stål) is a devastating pest that causes severe rice yield losses in Asia. Introducing multiple BPH resistance genes into rice cultivars is an effective and sustainable way to mitigate yield losses. A traditional rice cultivar, 'Rathu Heenati', has durable BPH resistance due to multiple resistance genes (including and ) and quantitative trait loci (QTLs).

Development and characterization of near-isogenic lines for brown planthopper resistance genes in the genetic background of rice 'Sagabiyori'.

The brown planthopper (BPH: Stål) is one of the most destructive insects in rice production. The use of host plant resistance has potential to reduce damage caused by BPH. The heat tolerance rice 'Sagabiyori', with superior grain quality and high soluble starch in the stem, is highly susceptible to damage by BPH.
