Abstract: A series of experiments was carried out on the induced resistance of tobacco to TMV. Using the S30 and L1, the resistance to TMV had been induced on the cure tobacco (NC 89, G140), white burley tobacco (N. tabacum), and N. glutinosa (the rate: 19.5%-35.6%). N. glutinosa and white burley tobacco could react to necrosis in earler period and narrow the necrotic spot. The progenies of induced tobacco plant remained to express a higher resistance (the rate: 25.2%-42.6%). Through inducing the resistance in the same variety of tobacco (G140) for three generations with L1 at seedling and flowering stages, the resistance in the progenies would increase generation by generation. The induced resistance rates were of F1, F2 and F3 16.98%, 27.94% and 36.42%, respectively.
