Abstract:
Cucumber (Cucumis sativus L.) is one of the most important vegetable crops of the family Cucurbitaceae, grown extensively in tropical and sub-tropical parts of the country. Cucumber production is greatly hampered by cucumber mosaic virus (CMV). A survey was conducted in three districts (Jammu, Samba and Kathua) of Jammu division during 2019 and 2020 and it was found that cucumber mosaic disease was prevalent in all locations and the overall incidence of disease in Jammu division was found maximum (34.66%) in Bishnah of Jammu district and minimum (21.33%) in Hirangar of Kathua district during 2019 while during 2020, maximum disease incidence of 36.00% was recorded from Akhnoor of Jammu district and minimum (20.00%) was recorded from Hirangar of Kathua district. Infected samples collected during the survey were brought under laboratory conditions for detection of the virus by serological means through DAS-ELISA and the overall result showed positive reaction with CMV specific antibody thus confirming the presence of cucumber mosaic virus.
