Yozgat İli Çerezlik Kabak (Cucurbita pepo L.) Ekim Alanlarında Görülen Virüslerin Belirlenmesi

Abstract

Cucurbits (Cucurbitaceae family) consist of 119 genera and 825 species and are cultivated worldwide, especially in tropical and subtropical regions. In the world, squash (Cucurbita pepo L.), watermelon (Citrullus lanatus (Thunb) Matsum&Nakai), cucumber (Cucumis sativus L.), and melon (C. melo L.) are the most cultivated cucurbit species as vegetable crops. Squash is grown for fresh consuming, as well as its seeds are used like a snack in Turkey. Viruses are one of the most destructive pathogen groups on squash which is grown for seeds in Yozgat province. In this study, it was aimed to determine the virus infections in economically important squash planting fields in the province. Totally 140 plant samples which show widespread virus symptoms such as mottling, shoe-string, mosaic, stunting, curling, vine decline, distortion, and blistering were collected from plants in 2017. In this study, DAS-ELISA method is used for identifying the virus infections on the plant samples. According to the results of the DAS-ELISA 84.28 % of plant samples were infected with Cucumber mosaic cucumovirus (CMV), Watermelon mosaic potyvirus (WMV), Papaya ring spot potyvirus-watermelon strain (PRSV-W), Zucchini yellow mosaic potyvirus (ZYMV), and Squash mosaic comovirus (SqMV). The prevalent virus was WMV with the ratio of 57.85 %. It was followed by ZYMV which was detected on the samples at the ratio of 53.57 %. Besides, double and multiple virus infections were determined commonly in the samples. Especially, ZYMV+WMV mixed infections were common. The infection of Cucumber green mottle mosaic tobamovirus (CGMMV) wasn’t determined in the survey area.
