Plant resistance has been recognised as the most desirable and economic tactic in the management of rice brown planthopper, Nilaparvata lugens (Stal). Three modalities or mechanisms of resistance has been utilised well in breeding for resistance. The recent development in the use of molecular markers in QTL analysis facilitate easy manipulation of phenotypically complex traits. This paper reviews the studies of mechanisms biochemical bases and genetics of resistance to brown planthopper in rice.
