Potato production impacts of the association trichodorids and TRV in naturally infected fields
| Resumo: | An investigation was conducted to determine the effect of soil-born Tobacco rattle virus (TRV) isolates on yield and some quality attributes of 8 potato cultivars (Agata, Amorosa, Almera, Cunéria, Kondor, Picasso, Raja and Stemster) in Portuguese growing areas. Preliminary results revealed that some attributes (canopy growth, total yield, tuber numbers and yield within size grades, tuber spraing symptoms and secondary growths) are severely affected in the sites with viruliferous trichodorids transmitting TRV. It was shown that TRV has real conditions for survival and cause economic impact in potato crop in these regions. These results have potential interest to all potato growing countries. |
