Evaluation of the reaction of greenhouse cucumber cultivars inoculated by the infectious clone of Tomato leaf curl Palampur virus

Abstract

Tomato leaf curl Palampur virus (ToLCPMV) is a destructive bipartite begomovirus which have recently been reported from India and Iran. Currently, ToLCPMV is known as the main factor causing yield loss in tomato and different cucurbits (other than watermelon) especially in greenhouse cucumbers in central and northern Iran. In this study, the reaction of sixteen cucumber cultivars was evaluated against inoculation by a ToLCPMV infectious clone under greenhouse conditions. Results showed that among all tested cultivars, Kian showed a minimum infection. Furthermore, this cultivar showed lower disease progress in compare to other cultivars and relatively recovered from disease. According to this study, in compare to other greenhouse cucumber cultivars, Kian is relatively resistance. However, more studies are needed to found or produce more reliable source of resistance.
