History of the Program

The first full-time researcher was stationed at the San Luis Valley Research Center in 1956. Mr. James Twomey conducted a potato selection program based on seedling tubers from other programs around the US, primarily the USDA in Beltsville, MD and Prosser, WA. In 1979, under the leadership of David Holm, the Colorado State University Potato Breeding and Selection Program was initiated. As the program evolved, the number of first year seedlings planted for selection grew from approximately 40,000 to 90,000-100,000. Centennial Russet was named in 1976. This was the first cultivar released by Jim Twomey during what may be referred to as the modern area of the Program. Since that time, another 27 cultivars/clonal selections have been released including russets, reds, specialties, and chippers. Another 19 cultivars have been cooperatively released with various universities, the USDA-ARS, and Agriculture and Agri-Food Canada.

Dr. David G. Holm
David G. Holm was born in Southeast Idaho and raised on a family farm near Shelley in Bingham County. Potatoes, grain, and alfalfa were the primary crops raised. He credits his Dad and Grandfather with instilling in him an interest in potatoes, and his 7th grade science teacher with helping him decide on a career in science when he challenged the class to start thinking about the future and what they wanted to do for a living. Dr. Holm received his B.S. (1972) and M.S. (1974) from the University of Idaho and his Ph.D. from the University of Minnesota (1977). Dave began his professional career and is currently a Professor in the Department of Horticulture at Colorado State University located at the San Luis Valley Research Center, where he served as Superintendent from 1983–1997. Dave’s principal research responsibilities include the breeding and selection of new potato cultivars through traditional hybridization methods. Development of seed stocks of advanced selections for grower evaluation and seed increase is also an integral part of his program. He maintains close interaction with various research, extension, and production segments of the potato industry in Colorado and other major potato production areas of the US. He considers these relationships critical to the release and successful adoption of new cultivars. During Dave’s tenure, 22 cultivars have been released. He has cooperated with other universities, the USDA-ARS, and Agriculture & Agri-Food Canada in the release of another 19 cultivars. He also has developed five clonal selections of Sangre and Russet Norkotah.

Caroline Gray
Caroline is originally from Virginia Beach, VA. She received her B.S. (1998) and M.S. (2001) from Virginia Tech. She worked as a Research Associate for the Soybean Breeding Programs at Virginia Tech (2001-2004) and at the University of Arkansas (2004-2010). She is currently the Assistant Program Lead for the Potato Breeding and Selection at Colorado State University located at the San Luis Valley Research Center.

 

 

 

Beth Niebaum
Beth is originally from Blair, NE. She received her B.S. (2015) in Plant Biology specializing in Biotechnology and M.S. (2021) in Agronomy with a Statistics minor from the University of Nebraska-Lincoln. During her time at UNL she worked with the Turfgrass Program, specifically for the Buffalograss Breeding Program. Beth is a Research Associate working for the Potato Breeding and Selection at Colorado State University located at the San Luis Valley Research Center.
 

 

Kate Peterson

Kate Peterson graduated from Southern Illinois University with a bachelor’s degree in Biological Sciences in 1992. She worked for couple of years doing seasonal work in Colorado, and then in Oregon before obtaining year-round work in Oregon for the Bureau of Land Management. The work mainly focused on vegetation trend and inventory for both grazing management and general land management purposes. She went back to get a graduate degree in 1994 and graduated with a Master’s of Range Science in 1997 from Utah State University. The degree heavily emphasized remotely sensed (satellite) imagery and statistical prediction methods for potential plant community distributions. She worked briefly for the U.S. Forest Service in southern Nevada after obtaining her master’s degree before moving to the San Luis Valley of Colorado. Between 2010 and 2020, she took a hiatus from biology to work in data and reporting for a non-profit healthcare organization in southern Colorado. She is now looking forward to getting back into biology-related work with CSU.

Jeremy Logrono.  Jeremy’s project was focused on screening carotenoids in potato germplasm using the new technology of Rapid Evaporative Ionization Mass Spectrometry (REIMS)/iknife and using the HPLC analytical method. Evaluating the potential of REIMS/iknife to screen carotenoids may improve the efficiency and precision of selecting high carotenoid potato lines. He also studied the biological functions of the role of high carotenoids in potatoes to the human health.

Impacts

Colorado State University released 28 potato cultivars, including five clonal selections, and cooperated with other agencies in the release of another 19 potato cultivars. Another four selections have been disclosed and will be named soon.

Colorado cultivars and clonal selections accounted for 36% of the 7,858 acres of Colorado certified seed accepted for certification in 2018. Advanced Colorado selections accounted for another 2% of the seed acreage.

Colorado State University releases accounted for 37% of the estimated 51,900 acres planted to fall potatoes in Colorado in 2017. Primary Colorado cultivars planted were Canela Russet (10.4%), Russet Norkotah-S8 (10.4%), Russet Norkotah-S3 (7.5%), Centennial Russet (4.3%), and Rio Grande Russet (4.2%).

Four of the top 20 russet cultivars grown for seed in the U.S. [Silverton Russet (#7), Canela Russet (#11), Centennial Russet (#12), Rio Grande Russet (#18)] in 2018 were developed by the Colorado program. Twenty-nine percent of the Russet Norkotah acreage (including line selections) was attributed to Colorado Russet Norkotah Selections 3 and 8. For reds, Sangre and Colorado Rose ranked #7 and #11, respectively. For chippers, Chipeta ranked #10. For colored-fleshed specialties, Purple Majesty and Mountain Rose ranked #1 and #2, respectively.

Collaborative Research

The Colorado Potato Breeding and Selection Program relies on the invaluable cooperation of several growers, shippers, research and extension personnel to assess the production, adaptability, marketability, and other characteristics of advanced selections.
