Abstract

Plant hoppers (BPH and WBPH) are very important pest of rice causing significant yield losses (30%) in Asian countries. Identification and Cultivation of resistant varieties is better and environmentally friendly approach. So one hundred three released rice varieties developed at National Rice Research Institute, Cuttack were evaluated for Brown Plant Hopper (BPH) and White Backed plant Hopper (WBPH) in net house of NRRI, Cuttack during Kharif 2019. TN-1 and PTB 33 are used as susceptible and resistant check in this experiment respectively. Two varieties namely Lunasampad and Gayatri showed moderately resistant reaction with SES Score 3 to BPH. Six varieties such as CRDhan 204, Tapaswini, Kalyani-2, Pradhandhan, Gayatri and Kshira showed moderately resistant reaction with SES Score 3 to WBPH. The variety Gayatri showed moderate resistant to BPH and WBPH. None of the variety are resistant to BPH and WBPH. These varieties can be popularised in hopper endemic areas and can be utilised in varietal development programme.

Conclusion

The varieties viz., Lunasampad and Gayatri can be popularised in BPH endemic areas and utilised in varietal development programme. Similarly the varieties such as CRDhan 204, Tapaswini, Kalyani-2, Pradhandhan, Gayatri and Kshira can be grown in WBPH endemic areas and used as donors in hybridisation programme.
