Abstract

Initial field screening in station trials (2021-2024) followed by evaluation under All India Coordinated Research Programme on Rice (AICRPR) (2022 to 2023) revealed ten Pattambi entries viz., RP5564 PTB 2-4-1-5, 0614- 13-15-7-1-2, RP5564 PTB 2-4-2-1-2, RP5564 PTB 1-4-2, 0614-13-15-7-1-1, RP5564 PTB 1-4-1. RP5564 PTB 1-3. 0614-1-6-21-1-2, 0614-1-6-21-1-4 and RP5564 PTB 2-4-2-1-1 were found resistant to rice leaf folder in station trials and multilocational trials were promising in fifteen locations across India during the test period. Six entries viz., RP 5564 PTB 2-4-2-1-2, RP 5564 PTB 1-4-2, RP 5564 PTB 2-4-2-1-1, 0614-1-6-21-1-2, RP 5564 PTB-1-3 and RP 0614-13-15-7-1-2 were found promising against both stem borer and leaffolder.
