Identification of Rice Tungro Disease (RTD) tolerant traditional varieties of rice (Oryza sativa L.) of West Bengal using forced inoculation methods with insect vector, green leafhopper (GLH), Nephotettix virescens (Distant).

Abstract :

 A majority of cereal viruses are disseminated among plants by insect vectors. Rice tungro disease (RTD) is associated with two viruses—rice tungro bacilliform virus (RTBV) and rice tungro spherical virus (RTSV) which are transmitted by the green leafhopper (GLH) Nephotettix virescens (Distant). Rice varieties differ greatly in resistance/tolerance towards RTD. Adaptation by populations of GLH has led to a eakdown of resistance in many of these varieties. Identification of new varieties tolerant to tungro, which may be used for future crop improvement, is imperative in the disease management programme
