The Evolution of Potato Varieties
Researchers have dedicated decades to breeding better potatoes specifically for chip production, adapting to changing market demands and agricultural challenges. David Douches, a professor at Michigan State University, leads the Potato Breeding and Genetics Program, focusing on developing potato varieties that can thrive in diverse climates, resist diseases, and maintain quality during storage. His recent innovation is a bioengineered potato that can be stored at colder temperatures without rotting, which is currently undergoing commercial testing.
The potato industry is dynamic, with evolving consumer preferences influencing the types of potatoes needed. For instance, the shift towards snack-size portions has increased the demand for smaller chipping potatoes. In the United States, approximately 50 unique potato varieties are cultivated for chips, with Michigan being the leading state for chip production, contributing significantly to the state's $2.5 billion potato industry.
Collaborative Efforts in Potato Breeding
The collaboration between researchers, farmers, and potato chip manufacturers is a notable aspect of this industry. Phil Gusmano, vice president of purchasing at Better Made Snack Foods, emphasizes the importance of this partnership, stating that their input is crucial for developing potatoes that meet processing needs. The breeding process itself is complex, often taking up to 15 years due to the potato's intricate genetic structure, which includes four chromosomes per cell.
Douches highlights the challenges of breeding potatoes that can be stored for extended periods. Traditionally, harvested potatoes were stored at around 50 degrees Fahrenheit, but this temperature can lead to increased sugar levels, resulting in darker chips. Newer varieties, such as the Mackinaw potato, can be stored at lower temperatures and are resistant to diseases, allowing for more efficient local sourcing of potatoes.
Impact on the Industry
The advancements in potato breeding have significant implications for the chip industry. Better Made Snack Foods, which has been producing chips in Detroit since 1930, has benefited from these innovations. Gusmano notes that the company previously sourced potatoes from outside Michigan for part of the year but can now rely on local varieties that can be stored longer, reducing transportation costs and improving freshness.
The National Chip Program, a collaborative initiative involving Michigan State University and other institutions, evaluates around 225 new potato varieties annually, selecting 100 for further trials. This ongoing research is vital for ensuring that the potato varieties meet the demands of both producers and consumers.
Official Statements & Responses
David Douches remarked on the potato's complexity, stating, “We’re never able to fix a trait and carry that over to the next generation, so it’s very difficult to find a potato that has all the traits that we want.” This highlights the challenges faced in breeding efforts. Gusmano added, “Instead, they’re being shipped from an hour and a half away all year long,” reflecting the benefits of local sourcing due to improved potato varieties.
What's Next
As the potato breeding research continues, the focus will remain on developing varieties that can adapt to climate changes and consumer preferences, ensuring the sustainability and growth of the potato chip industry.
