Description Not Available
A total of 1110 ENRRD rice germplasm accessions were evaluated for their resistance to brown
planthopper, BPH in glass house by adopting internationally accepted standard seed box screening
technique and scored on 0-9 scale by following the IRRI method of standard evaluation system for
rice. Among 1110 rice germplasm accessions tested, 3 were categorized as Highly resistant, 24 as
resistant, 19 as moderately resistant, 192 as moderately susceptible, 509 as susceptible and rest of
other 363 genotypes were highly susceptible to BPH. The studies on antixenosis mechanism of
resistance for feeding by probing marks revealed that resistant entries, wereleast preferred by BPH
nymphs and adults with more number of probing marks The results indicate that the germplasm
accessions viz., IC 343457, IC 300168 and IC 377051 were highly resistant and possess non preference mechanism of resistance and are not preferred by BPH for feeding. The identified
resistant entries can be used in the breeding programmes to develop BPH resistant varieties.
