摘要： To differentiate tobacco mosaic virus (TMV) strains in southcentral China, strain identification of TMV isolates collected from fields of sweet peppers or chillies in the cities of Shanghai (30 degrees N), Wuhan (30 degrees N), Chengdu (30 degrees N), Lhasa (30 degrees N), and Dali (25 degrees N) was performed by using the series of TMV-resistant Capsicum spp, carrying the genes of L+, L-1, L-2, L-3, and L-4, respectively. As anticipated, no isolates were identified as Po strain, because all of the TMV isolates were collected from cultivars with a L-1 resistance gene. On the other hand, it was found that the P-1 and P-1,P-2 strains which can infect cultivars with the L-1 resistance gene were widespread in southerncentral China. In addition, the P-1,P-2,P-3 strains which can break down the resistance of cultivars with L-3 resistance gene was also detected in Shanghai. No isolates were capable of infecting C. chacoense Jacq. harbouring the L-4 resistance gene. Based on the study of the variability of TMV strains in China, methods for the breeding of sweet pepper for TMV-resistance were evaluated.
