Abstract

Papaya ring spot virus isolate from Bagalkot, Karnataka was evaluated for host range and molecular studies using artificial inoculation and PCR based methods. PRSV-P isolate had a limited host range. The experimental results showed that PRSV isolate was pathogenic to Carica papaya (Caricacea) along with Chenopodium quinoa (Chenopodiaceae) and Cucumis sativus (Cucurbitaceae) producing local lesion and mosaic symptoms respectively. However apathogenic to Phaseolus vulgaris (Fabaceae). Datura stramonium, Datura metel, Capsicum annum cv. California Wonder, Nicotiana tabacum and Nicotiana glutinosa (all Solanaceae).

Conclusion

PRSV isolate was pathogenic to Carica papaya (Caricacea) along with Chenopodium quinoa (Chenopodiaceae) and Cucumis sativus (Cucurbitaceae) producing local lesion and mosaic symptoms respectively. However apathogenic to Phaseolus vulgaris (Fabaceae). Datura stramonium, Datura metel, Capsicum annum cv. California Wonder, Nicotiana tabacum and Nicotiana glutinosa (all Solanaceae).
