摘  要:
Eight rice varieties with different resistances were inoculated with rice stripe virus and disease incidences of them were obtained. By means of statistical analyses, the disease coefficients of resistant, medium resistant, susceptible and hypersusceptible varieties are 0. 25-0. 45, 0. 46-0. 75, 0. 76~1. 05 and 1. 06~1. 65,respectively. The forecasting formula of rice stripe disease established with the varietal disease coefficient and the number of viruliferous insects y= (a+bx)c, a and b are regression coefficient , c is disease coefficient, was obtained, and which has been used for three years in Jiangsu Province, and the forecasted values coincide with practical disease incidences.
