Abstract

Preliminary screening studies against rice stem borer and leaf folder were conducted at Regional Agricultural Research Station, Pattambi during kharif 2016 and rabi 2016-17 involving 14 rice cultures and susceptible check TN 1. The promising rice genotypes were evaluated under All India Coordinated Research Project on Rice (AICRPR) Hyderabad during kharif 2017, 2018 and 2019 under Stem borer screening trial, Leaf folder screening trial and multiple pest resistance screening trial. The rice culture KAUPTB 0627-2-11 (Cul 06-1) offered resistance to stem borer (both dead hearts and white ears). Cultures JS1,3,5 and 7 showed tolerance to both Stem borer and Leaf folder while Cul M9 exhibited field tolerance to multiple pests like Stem borer, mixed population of planthoppers and leaf folder.
