摘要: Two sources of resistance to Rice yellow mottle virus were challenged in host passage experiments. Pronounced changes pathogenicity occurred over serial passages isolates inoculated partially or highly resistant cultivars. The encompassed the known existing pathogenic variability field isolates. Ultimately, high Oryza indica cv. Gigante was overcome and partial O. sativa japonica Azucena broke down. effect resistance-specific as different overcame resistance, may also be allele-specific cultivars carrying same gene. ability break not linked a initial did result higher content infected plants. Implications for breeding deployment are discussed.
