Scientists Discover Wild Potatoes Key For Stronger Spuds

Potatoes have been a staple of Britain’s diet for half a millennium, but new research suggests that limited genetic differences in potato lineages has left British and American spuds vulnerable to the disease that caused the Irish potato famine. Plant scientists at the University of Dundee and the James Hutton Institute have revealed that commercial potato crops are under constant threat of late blight, the pathogen behind one of Europe’s most devastating…

Sugar End Disorder and Stem-End Chip Defect Stress Factors and Management – A Spud Smart Webinar & Podcast

Sugar ends is a physiological disorder that can occur at a tuber’s bud or stem end. The disorder’s symptoms usually aren’t apparent until the tuber’s exposure to colder temperatures — around 10 C or below. The stress that causes the disorder’s development occurs early in the growing season and may be difficult to determine.   Stem-end chip defect is another serious threat affecting tuber quality for chip potato growers. What are the causes…

Community and Science Strengthens Industry

Robert Thornton, an extension vegetable specialist and professor emeritus at Washington State University has been attending Potato Association of America (PAA) annual meetings since the early 1960s. He says the biggest reason he has maintained his membership for more than five decades is it keeps him honest. “Every year is an opportunity to have your thinking questioned,” Thornton says. “You can stay isolated in your own area of concern and be very…

Build Soil Quality and Suppress Soil-Borne Pathogens to Improve Yields Study Concludes

Canadian potato farmers, facing rising production costs and increased pressure from global competitors, are always looking for ways to increase yields. Identifying obstacles limiting potato yields is part of the answer, and was the primary objective of a major five-year research project conducted in New Brunswick, Prince Edward Island and Manitoba, which wrapped up last year. Project partners in the industry-led study included McCain Foods Canada, Agriculture and Agri-Food Canada, Potatoes New…

Spud Smart Webinar: Fighting Common Scab

Common scab is a pervasive threat to some potato-growing regions in Canada. Lesions and cavities on infected tubers can render them unmarketable. Researchers and industry experts are still trying to determine why the pathogen is more prevalent in some fields than others as well as the best methods for fighting the disease. While growers use many different practices to control common scab, none have proven to be totally effective. During this webinar,…

Combatting Common Scab

COMMON SCAB, a bacterial disease that doesn’t affect yields but causes ugly lesions and cavities on infected tubers, which can render them unmarketable, is a pervasive threat in potato-growing areas across Canada.  It has likely been around for as long as people have been growing potatoes, but researchers are still trying to determine why the pathogen is much more common in some fields than others and what the best methods are for…

Potato Breeding: A European Approach, Part III

MARCEL BRUINS, editor of European Seed, sat down with the leaders of five major potato breeding companies in Europe to learn more about the challenges of breeding new potato varieties. Piet Smeenge, director of Kweekbedrijf Smeenge-Research; Vanessa Prigge, Crop Improvement project manager at Solana; Gerard Backx, CEO of HZPC; Jan-Paul Bandsma, product manager at de Nijs Potatoes; and Guus Heselmans, R&D manager of C. Meijer B.V., provided insight on this favoured crop. …

A Better Estimate of the Net Yield of Seed Potatoes with Vision Techniques

Growers of seed potatoes would like to know on which part of their parcel the potatoes grow best, and how the location influences the size of the potatoes. But during harvesting, hundreds of potatoes will roll into the harvesting machine at the same time. Wageningen University & Research is working with Aeres Hogeschool, the University of Amsterdam, Amsterdam Green Campus and several growers to study how this yield can be measured by…

The Benefits of True Potato Seed

Charles Miller, commercial director of Solynta, discusses true potato seed with Julie Deering, editor of Spud Smart’s sister publication, Seed World. Miller discusses the benefits of true potato seed, or potatoes grown from seeds instead of tubers. Solynta has been working on producing hybrid true seed potatoes through targeted breeding. Miller says true seeds don’t take as long to produce new varieties in comparison to tubers — which take about eight years to…
