Abstract:

Brown plant hopper (BPH), Nilaparvata lugens Stal is one of the most serious rice pest in India. Growing of resistance varieties is the most effective and environment-friendly strategy for protecting the crop from BPH. In the present study we evaluated the forty entries of plant hopper screening trial against BPH under glass house condition. The trial material was received from All India Coordinated Rice Improvement Programme (AICRIP) DRR, Hyderabad during kharif 2011. Two screening tests were conducted in plastic tray (42cmx32cmx7cm) under glasshouse condition. Ptb 33 and Tainching Native 1 (TN1) were used as resistant and susceptible check. BPH culture maintained in the glass house was used for the screening test. In the above rating scale particulars in scale and level of resistance were taken from standard evaluation system for rice but the ranges for percent dead seedlings were constructed to facilitate the rating based on percent seedling mortality due to BPH damage. According to the results entry MSN97 showed only 4.5 per cent seedling mortality, therefore, classified as highly resistant. The entry KAUM 172-1 was rated as resistant in which mean seedling mortality was 7.7 per cent. Moderate level of resistant was observed in KAUM 166-2 and CB 05-022 with 18.2 and 20.0 per cent mean seedling mortality, respectively. The rest of the entries were either moderately susceptible (27.1 to 59.7 per cent mortality) or susceptible (64.2 to 100 per cent mortality) against BPH.
