Abstract:

Among the plant hoppers, the brown planthopper (BPH) is a major threat to rice production and causes significant yield loss 25 per cent annually Nilaparvata lugens Stal. (BPH) is a typical phloem feeder. Both nymphs and adults suck sap from the leaves and leaf sheaths, which results in yellowing of leaves, reduced tillering, reduced plant height and increase in number of unfilled grains, whereas severe attack of BPH causes ‘hopper burn’ symptoms. It also transmits virus diseases like grassy stunt, ragged stunt and wilted stunt. Host-plant resistance is an effective environment friendly approach to reduce BPH damage and increase yield potential of cultivars. In this context in the present study an attempt was made to identify donors for BPH resistance by comparing three methods viz., field screening, honeydew test and nymphal survival test. By conducting field screening of 178 rice genotypes following standard evaluation system (IRRI, 2014), 17 genotypes were found to be resistant under field screening. These 17 genotypes were further used for conducting honey dew test and nymphal survival test in order to confirm the resistance which recorded only two and one resistant genotypes, respectively. During screening, BPT-5204 and PTB-33 were used as susceptible and resistant checks, respectively.
