Abstract/Description: | Thirty three genotypes including resistant check, PTB-33 and susceptible check, TN1 were evaluated under field and glasshouse conditions along with studies on mechanisms of resistance against West Godavari brown plant hopper (BPH) population. The genotypes, PTB-33, RP Bio 4918-230S, RP 2068-18-3-5 and Rathu Heenathi were resistant in seedling stage in glasshouse and showed high level of resistance under field condition. Similarly, these genotypes had high level of antixenosis, antibiosis and tolerance mechanisms which was reflected by lower nymphal survival, prolonged nymphal duration, more macropterous adults, lower honeydew excretion and more days to wilt. Two genotypes viz., OM 4498 and IR-62 showed moderate levels of field resistance. The other 26 genotypes were susceptible to West Godavari BPH population |
