e0“Six rice cvs. T(N)1 and Tapaswini (susceptible), IR 20 and IR67406-6-3-2-3 (moderately resistant), TKM-6 and Vikramarya (resistant) were tested against the rice tungro disease on yield parameters”
e3“Reduction in number of panicles per plant was found less in Vikramarya inoculated with RTV at 60 DAS (1.5%) and 40 DAS (1.9%). A significant decrease of 15.5% in number of grains per panicle was observed in cv. Vikramarya when inoculated with RTV at 20 DAS while a decrease of 16.3% was noticed in TKM-6 plants when inoculated with RTV at 20 DAS”
