Differentiation of rice tungro virus strains

摘要

IR-20, Utrirajapan, Virippu, Daya, Moti, Habiganj, Jeera, Saket-4, IR~48, IR-34 and TNI were used as differentials to differentiate various isolates of tungro namely Burdwan (West Bengal), Cuttack, Konark, Jajpur, Salipur, Bhadrak (Orissa) etc. Moti was susceptible to Cuttack and Salipur isolates. Saket-4 was susceptible to Burdwan and Jajpur isolates. Virippu cultivar was found susceptible to Konark isolate. Habiganj was susceptible to Bhadrak isolate. All other differentials were found resistant toall the tungro isolates.
