Evaluation of Different Cucumber Germplasm against Cucumber Mosaic Virus in Jammu, India

Abstract

Cucumber ( L.) is one of the most important vegetable crops of the family Cucurbitaceae, grown extensively in Cucumis sativus tropical and sub-tropical parts of the country. Cucumber production is under constant threat due to various fungal, bacterial and viral diseases. Among these, mosaic disease caused by cucumber mosaic virus (CMV) is the most predominant. Thus, the present study on screening of different cucumber germplasm against cucumber mosaic disease revealed that out of forty germplasm, two germplasm ., Dasher II and viz Poinsett were resistant whereas CS-13, CS-16, CS-51, CS-54, Fumiko-10 and Don-1 were found moderately resistant during both the cropping season (2019 and 2020). The presence of CMV in infected plants were then confirmed serologically using DAS-ELISA. The resistant and moderately resistant cucumber lines from our study could be further used by farmers in cultivation under integrated production systems and by breeders in developing new varieties resistant to CMV.
