Cucurbita ecuadorensis is a species ofsquash, described in 1965 as growing wild inEcuador.[3] Like most wild gourds and squashes, it is a creeping vine and is often found climbing over other vegetation.[1] It has been found only in the western provinces ofGuayas andManabí.[4] There is evidence that it was domesticated in Ecuador around 10,000 years ago, likely for itsseeds, but no direct records exist and it is no longer cultivated.[5] It is resistant to many diseases of cultivatedCucurbita species,[6] and has been used to breed resistance to several diseases into common squashes.[7] For example, researchers atCornell University usedCucurbita ecuadorensis to breed resistance topapaya ringspot virus,watermelon mosaic virus, andpowdery mildew, into commonCucurbita maxima cultivars.[7]Cucurbita ecuadorensis is listed on theIUCN Red List asvulnerable and is found protected in theMachalilla National Park.[1]
