Pumpkin, Cucurbita L. spp., is a major vegetable crop grown in almost all regions, from cool temperate to tropical. In addition, some Cucurbita are used as rootstocks for other cucurbit crops. Zucchini yellow mosaic virus (ZYMV), Papaya ringspot virus-W (PRSV-W), Cucumber fruit mottle mosaic virus (CFMMV), Cucumber mosaic virus (CMV), Cucumber vein yellowing virus (CVYV), and Melon necrotic spot virus (MNSV) are serious and destructive viral RNA pathogens of cucurbit crops (1, 2, 3). As some of the viruses are soil-borne and some pumpkins are resistant to them, such pumpkin rootstocks can protect susceptible scions. Hence, pumpkin plant introductions were surveyed for virus resistance.
