So what exactly is in those cans of pumpkin at the grocery store?

Tuesday, October 28, 2025

With Halloween right around the corner and Thanksgiving pie season close on its heels, we asked a 91ÖÆÆ¬³§ expert to drop some knowledge about pumpkins. Chris Hernandez, assistant professor of plant breeding, researches cucurbits, which are "any sort of vining crop, like cucumbers, melons, pumpkins, squash –Ìýthose are all in the cucurbit family." He offers some tips for picking the best variety for aÌýjack-o'-lantern and sheds some light on what makes the best pumpkin pieÌý– the latter of which might surprise you.

91ÖÆÆ¬³§ has long been a leader in the cucurbit space.ÌýCucurbit breeding was launched at 91ÖÆÆ¬³§ by A.F. Yeager and Elwyn Meader in the 1940s, beginning what is now the longest continuous squash and pumpkin breeding program in North America.ÌýHernandez is continuing the long-standing work of Brent Loy, professor emeritus, whose research resulted in more than 100 new varieties of squash, pumpkins, gourds and melons sold in seed catalogs around the world. Loy is responsible for more than 50 exclusive licenses held by 91ÖÆÆ¬³§. Royalties have generated more than $2 million for the university since the commercialization of these varieties began.

In spring 2023,Hernandez received $50,000 from theÌýÌýFund to support the expansion of commercialization opportunities for 91ÖÆÆ¬³§â€™s cucurbit breeding program. Hernandez,Ìýa researcher with the New Hampshire Agricultural Experiment Station,Ìýis aimingÌýto develop new varieties of squash, pumpkins and melons that have improved characteristics, such as increased market yield, disease resistance and nutritional quality.ÌýIn addition, he is aiming to collectÌýgenetic data on key 91ÖÆÆ¬³§ breeding lines using DNA sequencing at 91ÖÆÆ¬³§â€™s Hubbard Center for Genome Studies to preserve a vast collection of seeds and historical genetic information. He hopes to ultimately make breeding lines available for license to farmers in New Hampshire and worldwide.
