Biologist Jessica Savage answers a few of our questions about her research on the physiology behind giant pumpkin size.
In October 2014, a giant pumpkin grown by Beni Meier of Switzerland tipped the scales at 1056 kilograms (2323 pounds) and set a new world record for the heaviest pumpkin ever weighed. Modern competitive pumpkin growers have been imposing very strong selection on pumpkin size for decades. Pumpkin fruit size keeps climbing, and old records are broken every year or two (Savage et al. 2015).

Jeanne introduces the diversity of some American natives, the squashes in the genus Cucurbita.
Spring is officially here, and I have squash on my mind. We’ve ordered zucchini seeds for the upcoming summer garden but still have acorn squash from the fall sitting in the pantry (both are varieties of Cucurbita pepo). Our winter vegetable CSA box recently bequeathed to us the tastiest winter squash I’ve ever eaten, a Seminole pumpkin, which is a different variety of the same species (Cucurbita moschata) as the butternut squash sitting on the counter, destined for dinner. Now between last year’s hard winter squashes and the tender summer squashes to come seems a good time to remind ourselves of the origins and diversity of squashes in the genus Cucurbita.
