Brown planthopper(BPH),Nilaparvata lugens(Stal),is a destructive insect pest of *** damages the plants by sucking the plant sap from the phloem tissues and results in wilting of plants due to reduced chlorophyll and protein *** attacked plants do not bear any grains and cause'hopper bum*condition(Catindig et al,2009).Both nymphae and adults suck sap primarily at the base of the tillers,and therefore their presence goes *** is also responsible for transmitting various viral diseases like grassy stunt,ragged stunt and wilted stunt(Win et al,2011).The blanket use of insecticides to control this pest has resulted in natural enemy death,environmental pollution,insecticide resistance and population ***,there is dare need to develop alternative management strategy for this pest,and host plant resistance can be the effective,economical and chemical-free approach to control BPH.

Out of 1 989 wild accessions sown in seed boxes for screening, only 1 003 wild accessions with good germination were screened against brown planthopper(BPH), Nilaparvata lugens(St?l) under greenhouse conditions. The collection comprised of accessions from 11 wild species and African cultivated rice. The germplasm was screened for BPH following standard seed box screening technique in the greenhouse. As many as 159 accessions were identified as resistant during the year 2012 based on one year screening. A selected set of BPH resistant accessions were screened again during 2013. Based on the two years screening, seven accessions of O. nivara(AA), one accession of O. officinalis(CC), seven accessions of O. australiensis(EE), five accessions of O. punctata(BB and BBCC) and nine accessions of O. latifolia(CCDD) were confirmed to be resistant to BPH. So far no BPH resistance genes have been identified and designated from O. nivara and O. punctata, hence these may act as new sources of resistance.
