Abstract: Pumpkin (Cucurbita moschata Duch) is an important crop species for Indian agriculture of Cucurbitaceae family and is grown extensively throughout the year. Pumpkin is a common man’s vegetable consumed by both rich and poor alike. Pumpkin is an important article of diet, the main nutrients are lutein and both alpha and beta carotene, the latter which generates vitamin A in body. Among the various problems involved in the cultivation of pumpkin crop, insect, pest and diseases are of prime importance. Among the major diseases the viruses are most important pathogens of cucurbits (cucumber, watermelon, melon and pumpkins) belonging to the family Cucurbitaceae. More than 30 infectious viruses causing destructive symptoms and considerable economic losses were reported. Present investigation was undertaken in Kharif------ for the study of symptomatology and host range of mosaic disease of pumpkin. The result showed that, the symptoms shown by virus Isolate I were severe mosaic mottling, dark green blistering, leaf deformation, stunted growth and leaf malformation whereas the symptom shown by virus isolate II were vein yellowing, vein clearing, mosaic, stunted growth and smaller leaves. On the other hand host range study showed that isolate I was very narrow, mainly restricted to family Cucurbitaceae. Systemic symptoms were incited on Citrullus lanatus, Cucumis sativus L., Momordica charantia L., Cucumis melo L., Luffa cylindrical Roem, Lagenaria siceraria (M.), Trichosanthes anguina L., Luffa acutangula L., Cucurbita moschata Duch. whereas isolate II has a very limited host range only two species of Cucurbitaceae family was infected.
