Trees from thirty sweet orange groves were selected for detection and comparisom of citrus tristeza virus (CTV). Most groves were expected to be potential sources of more severe forms of CTV than are commonly ecountered in southern California. The initial evaluation was based on grafting pooled samples from several trees from a grove to grapefruit seedlings, which were subsequently evaluated for CTV symptoms. Ten trees from each grove were analyzed individually for CTV specific dsRNAs, and bark samples from the same trees were grafted to sweet orange seedlings which were subsequently analyzed for CTV specific dsRNAs. The dsRNAs. The dsRNA profiles tented to be fairly consistent for the trees in a given grove and varied from grove to grove. When variability was in evidence withing a grove, the trees with non-conforming dsRNA profiles profiles were invariably younger replacement trees. Specific bands that could be used to type CTV isolates were detected in the parental tree and in the sweet orange seedling used to propagate the CTV isolate in the greenhouse. A marker dsRNA (Mr 0.5 x 106) that is normally undetectable in typical California isolates of CTV was detected in some groves and an association was established between the detection of this dsRNA and the ranking for virulence established by the initial survey that was used as a basis for grove selection. |
