Identification and application of resistance genes to brown planthopper

E Zhiguo

Abstract

The brown planthopper(BPH) is one of the most serious insect pests in rice production.The breeding of varieties resistant to BPH by applying host-plant resistance has been recognized as an economic and effective measure for BPH control.Systematic genetic studies on rice resistance to BPH have been conducted in world since 1971.Up to December 2007,there are a total of 22 BPH resistance genes registered internationally or reported.Among them,12 and 10 out of the genes are dominant and recessive,respectively,and 18 of them have been located.Besides,some important resistant QTLs have been detected.Application of resistance to BPH was also discussed.
