Assessment of promising rice hybrids against insect pests under western undulating zone of Odisha

Eighteen rice hybrids were evaluated for their reaction against major insect pests at Bhawanipatna, Kalahandi, Odisha during wet season, 2013 and compared with two check hybrid rice i.e, Ajaya and Rajalaxmi developed by Central Rice Research Institute, Cuttack and one high yielding variety MTU 1001. Results revealed that two rice hybrids viz., RH 10428 and RH 10422 exhibited lowest incidence of stem borer, gall midge, leaf folder, brown planthopper and whorl maggot incidence with highest grain yield. Rice hybrids RH 10428 and RH 10422 can be incorporated as a varietal component in the IPM programme for the vertical increase of rice production in this area.
