Pressure bruise management aided by texture analysis

Pressure flattening in stored potatoes is a cause of significant economic losses for Colorado potato growers. Pressure flattening occurs as the tuber surface becomes depressed or flattened due to constant contact with a portion of an adjacent tuber and the additional weight of tubers above it in the pile. The development of pressure flattening is also a result of dehydration of the tubers that occurs before and after harvest, and during storage. We can offer a predictive tool to a storage manager in determining…  » Read more

CIP research aims to develop potato resistance

On this World Day to Combat Desertification and Drought (June 17), we look across the countries where the International Potato Center (CIP) operates for a roundup of work developing potato and sweet potato's drought resilience.  The UN observance, made official in 1995, is aimed at discussing ways in which countries can fight drought and aridity exacerbated by climate change, deforestation and other factors. Numerous CIP research projects aim to identify potato clones and varieties better suited…  » Read more

Potato pest alert: tuberworms

Potato tuberworm moths were found in traps at 42 percent of the fields monitored by Washington State University. The maps below compare potato tuberworm population densities (based on trapping data) this week and last week.   Monitoring If you are planning to harvest an early crop in the next 4 to 8 weeks, then you may want to take action, especially if you are in the Lower Columbia Basin. Monitoring the pest will help you decide whether control measures…  » Read more

Prospective Potatoes

Accumulation of high levels of reducing sugars during cold storage, known as cold-induced sweetening (CIS), is one of the more significant concerns for potato processing. This physiological change in tuber sugar concentration detrimentally impacts processing quality with unacceptably dark products and the production of acrylamide, a possible human carcinogen, following frying. Processing potatoes are commonly stored at 46 ̊ F to 54 ̊ F to mitigate the accumulation of reducing sugars. However, storage at colder temperatures (38-40 ̊…  » Read more

GM potato approved for field trials

The Department for Environment, Food & Rural Affairs in the U.K. have approved The Sainsbury Laboratory, Norwich’s (TSL) application to conduct field trials of genetically modified potato crops on a designated trial site at the Norwich Research Park between 2016 and 2019. The field trials are part of TSL’s Potato Partnership Project to develop a Maris Piper potato that is blight and nematode resistant, bruises less and produces less acrylamide when cooked at high temperatures. The project…  » Read more

Nutrient-rich purple potato developed

Purple potatoes might not be the first thing that comes to mind when trying to increase vitamin, mineral and antioxidant intake. However, a group of researchers from Colorado State University (CSU) have recently developed potato varieties that satisfy these nutritional needs and could act as a preventive measure to several diseases. The research team works with the CSU Potato Program and is composed of David G. Holm, a professor and potato breeder; Sastry S. Jayanty, a…  » Read more

Flower borders help reduce mosaic in Russet Norkotahs

In recent years, there has been an increased interest in improving soil health through changing traditional agricultural practices. One way to accomplish this is to increase overall species diversity in agricultural ecosystems. Having diversity in plant species can improve crop health in other areas as well. In 2014, a flower mix used as a crop border was found to be effective at reducing the spread of mosaic (primarily caused by PVY) in the highly susceptible potato variety, Russet…  » Read more

Potato plant boosts defenses against attacks

Potato plants boost the chemical defenses in their leaves when Guatemalan tuber moth larvae feed on their tubers, according to researchers at the Cornell-affiliated Boyce Thompson Institute (BTI). The potato’s response protects against leaf-eating pests, ensuring the plant can maintain sugar production to continue growing tubers during the moth larvae infestation. The study, led by Georg Jander, BTI professor, and Katja Poveda, Cornell assistant professor of entomology, appears in the journal Oecologia. The discovery may one day help reduce potato damage from…  » Read more

NPC offers scholarship for graduate students

The National Potato Council (NPC) is accepting applications for its $10,000 graduate-level scholarship. The scholarship must be applied toward the 2014-2015 academic year. Applicants must be graduate students pursuing advanced studies, master’s degree or higher, that will improve the future of the U.S. potato industry. Selection is based on academic achievement, leadership abilities and the potential commercial value of the applicant’s academic work. Application deadline is June, 30. The scholarship winner will be announced in…  » Read more
Spence named director of industry outreach for WSPC

Spence named director of industry outreach for WSPC

The Washington State Potato Commission (WSPC) has named Raina Spence as its new director of industry outreach. Spence's role at the commission will be focused on providing technical advice and assistance to the industry on food safety, sustainability programs and pest and plant diagnostics. She will oversee various research projects funded by the WSPC and coordinate efforts with other research institutions to develop key educational information. Findings from these initiatives will be distributed to growers,…  » Read more
