Abstract:
A total of six hundred and thirty (630) rice genotypes were evaluated against brown planthopper (BPH) under field screening during kharif 2022 at RARS, Maruteru, West Godavari district, A. P., India with an objective to identify new sources of resistance against brown planthopper in rice. The results of field screening conducted during kharif 2022 revealed that sixty five (65) rice genotypes were found resistant with damage score (DS) of “1”. Among these 65 rice genotypes, 13 genotypes viz., AM845, ADW262, BDW206, BDW207, BDW208, BDW209, BDW210, BE797, BM552, BM573, CL460, CM455 and CM456 possessed Bph32 gene. Further, 94 genotypes were moderately resistant (DS-3), while the rest (470) were susceptible to brown planthopper with damage score of ≥5.
