Abstracts

Pumpkin common mosaic caused by number of viruses which includes Cucumber mosaic virus (CMV), Watermelon mosaic virus 2 (WMV2), Papaya ring spot virus-watermelon strain (PRSV-W), and Zucchini yellow mosaic virus (ZYMV) and Pumpkin yellow vein mosaic disease caused by Pumpkin yellow vein mosaic  virus (PYVMV)  have appeared as the most important, serious and often overwhelming diseases of pumpkin  throughout India (FAOSTAT, 2010, Jayashree, 1999). Out of 6 pumpkin germplasms tested, two cultivars were found resistant (R), 2 moderately resistant (MR), and two moderately susceptible (MS). Minimum incidence  17.16  % was recorded from variety Kumra ( a local variety very recently being  introduced  in  this locality)  followed by  variety  Pusa-shrabani  24.28 %. Significant differences among all the varieties were observed  in terms of their response to common mosaic disease. Pumpkin variety, Kumra and Pusa-Shrabani can be considered as prominent varieties against common mosaic under the environmental conditions of lateritic zone of West Bengal.
