A Preliminary Study on the Virus Groups of Tomato and Strain Differentiation of Tabacco Mosaic Virus (TMV) in China
Abstract: The differentiation of TMV strains was studied and identified all over the country according to the principle of classification of TMV strains proposed by Pelham, J. (1938). The results of identification show that there is a strain differentiation of TMV on tomato in China where four strains were isolated from tomato fields. The strain 0 which only infects susceptible varieties (+/+) holds the most considerable proportion in TMV population in nature, which is widely distributed in most of the tomato produci...
