Abstract
Cucurbitaceous crops are major vegetable group cultivated widely in India. Leaves of cucumber, bitter gourd and watermelon were observed with virus like yellowing symptoms of interveinal chlorosis. DAS-ELISA and RT-PCR assay were performed to identify the infecting virus. Nucleotide sequence analysis confirmed the association of Cucurbit yellow stunting disorder virus (CYSDV), a Crinivirus belonging to family Closteroviridae. This study documented the prevalence of CYSDV on cucurbitaceous crops for the first time from India.
