Russet Burbank

language culture Maturity 11-13 Next article →

The Russet Burbank is a specific type of potato cultivar. A cultivar is a plant variety that has been produced through selective breeding. This potato is the most widely grown variety in North America. It is famous for its dark brown skin and white flesh. The texture of the flesh is described as dry and mealy. These physical traits make it ideal for specific cooking methods. It is a top choice for baking and mashing. It is also the primary potato used for making french fries. Many people now consider it the standard potato for comparison.

Growing the Russet Burbank involves several distinct botanical features. The plants are medium in size with medium-thickness stems. These stems are prominently angled rather than smooth. The leaves are also medium-sized with large leaflets at the ends. The flowers produce medium-sized buds that are dark green. These buds drop from the plant quite readily. The tubers themselves are large and long. They often grow in a cylindrical or slightly flat shape. The skin features many eyes that are evenly distributed. These eyes can produce brownish-purple sprouts as they grow.

This variety has a complex lineage involving many different breeders. The history began in 1853 with Chauncey E. Goodrich. He imported a plant called Rough Purple Chili from South America. He wanted to add diversity to American potato stocks. At that time, many stocks were susceptible to late blight. Goodrich bred Garnet Chili from the Rough Purple Chili. Later, Albert Bresee bred Early Rose from Garnet Chili. In 1873, Luther Burbank bred a plant called Burbank from Early Rose. The Russet Burbank is a mutation of this Burbank plant.

There are many different stories about when this potato was released. Some people incorrectly reported it was selected in 1914. They believed a Colorado grower named Lou D. Sweet selected it. However, a 2014 study corrected this historical record. The study confirmed it was originally released in 1902. It was released by a company called L. L. May & Co. At that time, the variety was known as the Netted Gem. It was also formerly known as the Russell. Eventually, it became popularized as the Russet potato in American stores. Because potatoes grow from tubers, they could not be patented in the United States.

The popularity of the Russet Burbank has changed significantly over time. In 1930, it accounted for only 4% of potatoes in the US. Several factors caused its massive growth in the following decades. First, the introduction of irrigation in Idaho helped growers. They found they could produce large potatoes easily. These large tubers were perfect for the baking market. Next, the invention of frozen french fries in the 1940s helped. The rise of fast food restaurants in the 1950s helped even more. By the 2010s, it held 70% of the ultra-processed potato market in North America. It also covers over 40% of the potato growing area in the US.

Specific industries rely heavily on the unique shape of this tuber. McDonald's is a notable example of a user. As of 2009, the Russet Burbank was McDonald's top tuber. Restaurants favor it because its long shape produces long french fries.

The potato is also very efficient for long-term storage. It can be kept for up to five months. This works well at a temperature of 7 °C, or 44.6 °F. It does not require special gases to stop the sprouts from growing. However, growers must watch for internal black spot, known as IBS. They must also avoid harvesting too early to prevent skinning issues.

Understanding the Russet Burbank also requires looking at its disease resistance. It is highly resistant to a disease called black leg. It also shows moderate resistance to common scab. It can resist some forms of fusarium dry rot. These include Fusarium oxysporum and F. sambucinum. However, it is still susceptible to other biological threats. It can be affected by late blight, which is caused by Phytophthora infestans. It is also vulnerable to leaf roll, verticillium wilt, and PVY. Scientists can use genetically modified potatoes to help resist the Colorado Potato Beetle. This shows how the potato connects to the field of modern genetics.
