Cucurbita pepo includes eight groups of edible cultivars—pumpkins, scallops, acorns, crooknecks, straightnecks, vegetable marrows, cocozelles, and Zucchinis. The pumpkins, scallops, and possibly the crooknecks are ancient groups that developed along separate lines of domestication in North America. Incipient forms of all the other five groups appeared in botanical herbals of Europe by 1700. Modern forms of the vegetable marrows, cocozelles, Zucchinis, and acorns appeared in Europe prior to 1860… 

Parallel Evolution Under Domestication and Phenotypic Differentiation of the Cultivated Subspecies of Cucurbita pepo (Cucurbitaceae)

Among the evolutionary developments common to the two subspecies are the increased size of the plant parts, less plant branching, and premature loss of chlorophyll in the exocarp of the fruits.

Germplasm enhancement of Cucurbita pepo (pumpkin, squash, gourd: Cucurbitaceae): progress and challenges

Fruit quality and flavor enhancements of pumpkins and squash have been and are being accomplished largely by the consumer-oriented breeders at research and academic institutions, however, lack of support for these breeding programs is jeopardizing the continued consumer- oriented fruit-quality enhancement of C. pepo germplasm.

Genetic Resources of Pumpkins and Squash, Cucurbita spp.

Pumpkins and squash, Cucurbita species, can be found in fruit and vegetable markets almost everywhere and are primarily grown for consumption of their young or mature fruits, seeds, extraction of oil from the seeds, and ornament.

Genetic relationships and evolution in Cucurbita pepo (pumpkin, squash, gourd) as revealed by simple sequence repeat polymorphisms

There was no evidence for crossing between subspecies after domestication, and accessions of the longest-fruited cultivar-group, Cocozelle, radiated bidirectionally, indicating independent selection events for long fruits in subsp.

Genetic relationships in Cucurbita pepo (pumpkin, squash, gourd) as viewed with high frequency oligonucleotide–targeting active gene (HFO–TAG) markers

The results indicate that the Old World pumpkins as well as the long-fruited cultivar-groups of C. pepo (cocozelle, vegetable marrow, and zucchini) evolved from spontaneous crossing and gene exchange between pumpkinsderived from northern North America and pumpkins derived from southern North America within the first decades of European contact with North America.

Transcriptomic Analysis Reveal the Molecular Mechanisms of Seed Coat Development in Cucurbita pepo L.

Cucurbita pepo is one of the earliest cultivated crops. It is native to Central and South America and is now widely cultivated all over the world for its rich nutrition, short growth period, and high

Ex situ and in situ conservation of these species that includes phenotypic assessments are needed to better utilize the wealth of genetic resources available for pumpkin and squash crop improvement.

Breeding Squash and Pumpkins

Although Cucurbita cultigens are considered highly outcrossed under natural conditions, they can be highly inbred without readily apparent inbreeding depression, and are often classifi ed in breeding books along with other self-pollinating crops.



American Origin of the Cultivated Cucurbits. I. Evidence from the Herbals. II. Survey of Old and Recent Botanical Evidence

In the course of his investigation on the association of the cultivated cucurbits with the various Amerind cultures of the Southwest, the writer had occasion to examine most of the published work that concerns the origin of this group.

History and Distribution of the Cultivated Cucurbits in the Americas

Abstract All species of Cucurbita (which includes squashes, pumpkins, and the common, small, yellow-flowered gourds) are native to the Americas. Their center of origin lies in Mexico where most of

Numerical analysis of allozyme variation inCucurbita pepo

Cucurbita pepo, represented by cultivated forms of squash, pumpkins, and ornamental gourds, is a morphologically diverse species. Although several classifications of the cultivars have been proposed,

Allozyme variation in cultivars of Cucurbita pepo L.

Despite the outcrossing nature of the species, allozyme polymorphism within most cultivars was low and did not seriously interfere with the analysis, indicating that such loci could be used to screen for the percentage of hybrid seed obtained from crosses.

Numerical Analysis of Seed Morphology in Cucurbita Pepo

Canonical variate and prin- cipal component analyses revealed variation in the size and shape of C. pepo seeds which was similar to recently documented patterns of allozyme variation and appears to reflect effects of human selection.

Cucurbits and cultures in the Americas

The cultural history of the cucurbits indicates a very strong tendency towards conservative crop husbandry among pre Columbian and post-Columbian peoples in that they tended to grow essentially the same cultivars over long periods of time.

The Influence of Gene B on Fruit Development in Cucurbita pepo

The influence of gene B on various growth parameters in 3 genetic backgrounds of Cucurbita pepo L. cultivars ‘Early Prolific’, ‘Small Sugar’, and ‘Fordhook Zucchini’ is reported. While fruit size is


The genus Cucurbita is a comparatively small closed system composed of about two dozen species concentrated in a relatively small land mass, and presents an opportunity to compare the evolution of closely related species under cultivation contrasted with the development of species in nature.


The results indicate that the differences in harvest speed among the cultivars were based mainly on camouflage of the green fruits and contrast of the golden-yellow fruits with the green foliage.

Excavations conducted since Chomko's initial discovery in 1974 of Cucurbita pepo seeds have clarified their stratigraphic and radiometric context as well as delineated an earlier archaeological unit,
