| Abstract;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.DEG.N), Wuhan (30.DEG.N), Chengdu (30.DEG.N), Lhasa (30.DEG.N), and Dali (25.DEG.N) was performed by using the series of TMV-resistant Capsicum spp. carrying the genes of L+, L1, L2, L3, and L4, respectively. As anticipated, no isolates were identified as P0 strain, because all of the TMV isolates were collected from cultivars with a L1 resistance gene. On the other hand, it was found that the P1 and P1,2 strains which can infect cultivars with the L1 resistance gene were widespread in southerncentral China. In addition, the P1,2,3 strains which can break down the resistance of cultivars with L3 resistance gene was also detected in Shanghai. No isolates were capable of infecting C. chacoense Jacq. harbouring the L4 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. (author abst.) |
