Pitrat M. (ed): Cucurbitaceae 2008, Proceedings of the IXth EUCARPIA meeting on genetics and breeding of Cucurbitaceae, Avignon (France), May 21-24th, 2008, pp. 347-351.
Abstract: The tropical pumpkins Cucurbita moschata Duchesne and C. argyrosperma Huber are often found growing together. Both C. argyrosperma subsp. argyrosperma (the domesticated cushaw squash) and the wild species C. argyrosperma subsp. sororia (L.H. Bailey) Merrick & Bates are found together in Central America. Several reports indicate that plants displaying a phenotype combining traits of both species occur, suggesting gene flow between species. This research studied gene flow between species by evaluating progenies from field plantings of C. argyrosperma (both subspecies) interplanted with C. moschata and allowed to open-pollinate. The progenies evaluated were from C. argyrosperma seed parents. Morphological and species-specific RAPD markers demonstrated that C. moschata genes were introgressed into these open-pollinated progeny.
