To try a kiwiberry 鈥� the sweet, smooth-skinned, grape-sized cousin to the familiar fuzzy kiwi 鈥� is to love a kiwiberry. Now, a new partnership between UNH and a commercial plant producer aims to ensure that every bite of a kiwiberry is as delicious as the next one, a level of product control essential to growing the commercial kiwiberry market.

, a leader in kiwiberry breeding and the first team to genetically fingerprint all kiwiberry varieties in North America, has partnered with Hartmann's Plant Company of Lacota, Michigan, to genetically fingerprint the company鈥檚 in an effort to verify the identity of varieties recommended for growing in New England.

It鈥檚 an important 鈥渦nder the hood鈥� step toward moving kiwiberries from backyard gardens into commercial production, says , associate professor of specialty crop improvement and director of UNH鈥檚 kiwiberry program. Verification gives commercial growers, who may invest thousands of dollars and multiple acres into kiwiberry production, confidence to trust the identity of the kiwiberry varieties they鈥檙e planting.

Hale notes that unlike more familiar fruits, well established in our diets despite the occasional 鈥渂ad apple鈥� we might encounter, kiwiberries have one chance to win new fans. 鈥淭o build a mature fruit sector, you need standards around market quality,鈥� he says. 鈥淲hen you鈥檙e rolling out a new crop, there鈥檚 that moment when a potential consumer will taste the fruit for the first time. If the variety is wrong, if it鈥檚 not at peak ripeness, that person will simply conclude they don鈥檛 like kiwiberries, end of story.鈥�

鈥淯ntil this arrangement with Hartmann鈥檚, we had growers who were willing to grow kiwiberries and we had consumers who wanted them. Now we have a reliable genetic source to make it happen.鈥�

He adds that of the nearly 200 varieties of kiwiberries his team started with at the NH Agricultural Experiment Station鈥檚 Woodman Horticultural Research Farm, only a handful have proven themselves worthy of commercial production in the region. (Some, he says, are just awful. 鈥淲e have one that tastes like grass and pickles and a pine tree had a baby.鈥�)

Introduced to the U.S. from Asia in 1876, the kiwiberry (Actinidia arguta) has been grown as an ornamental vine in the Northeast for more than a century; Hale鈥檚 lab is leading the charge to bring the tropical taste complexity and nutritional superpowers of the kiwiberry to consumers. Hale estimates that the U.S. has between 200 and 300 acres total of commercial kiwiberry production, mostly concentrated in the Pacific Northwest; in New England, despite ideal growing conditions, 鈥淚鈥檇 be surprised if there are more than five acres.鈥�

Hale worked with听Hartmann鈥檚, the only nursery offering kiwiberry vines at a volume and price targeted to commercial growers, to genetically analyze the company鈥檚 kiwiberry inventory and validate the identities of their offerings.

鈥淭hese UNH-verified varieties will revolutionize the kiwiberry industry,鈥� said Danny Hartmann, president of Hartmann鈥檚 Plant Company. 鈥淭hanks to the work by Dr. Hale, we are more confident in recommending varieties to growers and nurseries. We will continue to produce quality, true-to-name kiwiberries for the success of all of our customers.鈥�

Working with , Hartmann鈥檚 licensed the resulting data, which allows them to add a UNH-verified mark to their plants and produces income for the UNH kiwiberry research program. This is the first intellectual property license related to the kiwiberry program.

鈥淎s a leader in kiwiberry research, UNH is proud to play a part in increasing commercial interest in the fruit,鈥� says Jenna Matheny, director of technology transfer for UNHInnovation, which manages the university鈥檚 intellectual property. 鈥淯NH has a long history as a land-grant听university听of using its world-class research and expertise to collaborate with industry and provide information and innovations that address ongoing agricultural challenges.鈥�

鈥淯ntil this arrangement with Hartmann鈥檚, we had growers who were willing to grow kiwiberries and we had consumers who wanted them,鈥� says Hale. 鈥淣ow we have a reliable genetic source to make it happen.鈥�
