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 80,000-85,000. 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 18 cultivars have been released including russets, reds, specialties, and chippers. Eleven additional cultivars have been cooperatively released with various universities, the USDA-ARS, and Agriculture and Agri-Food Canada.

Dr. David G. Holm
Dr. 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. In 1979, he initiated the Colorado Potato Breeding and Selection Program, which previously had been solely a selection program receiving seedling tubers from other programs. During Dave’s tenure, 18 cultivars have been released. He has cooperated with other universities, the USDA-ARS, and Agriculture &Agri-Food Canada in the release of another 11 cultivars. He also has developed five clonal selections of Sangre and Russet Norkotah.

Raven Bough. Screening Potato Germplasm for Flavor Utilizing HS-SPME/GC-MS and Sensory Panel Analyses

The development of potato cultivars with improved flavor in the San Luis Valley has the potential to expand the region’s fresh potato market by focusing on consumer appeal. Through analysis of existing cultivars, the objective of this project is to establish a flavor rating methodology for potato selections based on correlation of HS-SPME/GC-MS quantification of major flavor compounds and sensory panel tests. Flavor ratings will guide germplasm screening in the breeding process, which will enable the development of new cultivars with improved flavor.

Impacts

Colorado cultivars and clonal selections accounted for 32% of the 9,357 acres of Colorado certified seed accepted in 2015. Advanced Colorado selections accounted for another 1% of the seed acreage.

Colorado State University releases accounted for 42% of the 52,800 acres planted in 2015 to fall potatoes in Colorado. Primary Colorado cultivars planted were Russet Norkotah-S3 (13%), Canela Russet (10%), Russet Norkotah-S8 (10%), Centennial Russet (5%), and Rio Grande Russet (2%).

Six of the top 20 russet cultivars grown for seed in the U.S. [Russet Norkotah-S3 (#7), Canela Russet (#11), Silverton Russet (#13), Centennial Russet (#14), Russet Norkotah-S8 (#15), Rio Grande Russet (#20)] in 2015 were developed by the Colorado program. For reds, Colorado Rose ranked #8. For chippers, Chipeta ranked #10. For colored-fleshed specialties, Mountain Rose ranked #2 and Purple Majesty ranked #1 among red- and purple-fleshed cultivars.

 

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.
