High levels of genetic variation and differentiation in wild tropical gourds provide a novel resource for cucurbit crop improvement

PLANTS, PEOPLE, PLANET, Volume 6, Issue 4, Page 834-846, July 2024.
The genetic variation of crop wild relatives will be key for our survival, as environmental change represents an increasing global threat for agriculture and food security. Cucurbita lundelliana and Cucurbita okeechobeensis subsp. martinezii are wild relatives of cultivated squashes and pumpkins that could be used for crop improvement.
