Abstract:

Experiments were conducted to screen a set of rice accessions to assess their level of resistance to BPH infestation. Out of 25 rice entries subjected to Modified Seedbox Screening Test (MSST), 21 entries viz. Rasi, Chethunali, Ganthasala, Blue bonnet, Branava, Slivahaiva, Blue bell, Rajshree, WGL 14, White ponni, Aathira, Brimfer, Uttrirajappan, Basmati 370, Swarana, Vethi vedangan, Karanellu, Columbia 2, WAGWAG, White sannam and TN1 were found to be highly susceptible with the damage score ranging from 7.00 to 9.00. Three entries viz. Kakarathan, BG367-2 and Kavuni were found to be moderately resistant with damage score of 5.77, 5.81 and 6.73 respectively. Bharathi was found to be resistant with the damage score of 1.90. Four rice entries viz. Columbia 2, WAGWAG, White sannam and TN1 remained with damage score of 9.0 indicating their susceptibility to BPH. The accessions were subjected to screening based on days to wilt. Bromfer, Blue bell, BG367-2, Karkarathan, Kavuni and Uttrirajappan were showing delayed wilting compared to Bharathi.
