Indian citrus ringspot disease is an important viral disease in kinnow mandarin orchards where disease incidence upto 100 percent has been recorded. The disease is caused by Indian citrus ringspot virus (ICRSV), a positive sense flexuous RNA virus. The transmission of ICRSV is generally through bud-wood. Association of ICRSV with pollens of naturally infected flowers from Kinnow mandarins has been shown previously and this study demonstrates the presence of ICRSV in seed tissues. DAC-ELISA revealed presence of virus in seed coats but not in embryo and endosperm of seeds collected from the fruits of ICRSV infected kinnow plants. 18% of the infected seed coats were found to harbor the virus. The seedlings in the grow-out test did not show any symptom for two years and the virus could not be detected in seedlings by DAC-ELISA and RT-PCR. The present study indicated that ICRSV could be localized in the testa of seeds but its transmission to progeny was not observed. |
