Potato cultivars or selections included in this report were selected from recently released cultivars, advancing selections with release potential (numbered lines progressing through the trial process), or cultivars that are new to the U.S. Standard potato cultivars used by growers served as checks. For comparison, studies conducted in 2019 and 2020 evaluated red and yellow-skinned fresh potatoes.

In 2021, two trials were conducted to identify traits of red- and yellow-skinned potato cultivars and advanced selections at Crystal, N.D. Sixteen red-skinned cultivars and 32 yellow-skinned cultivars were evaluated. Plots were established in a commercial, non-irrigated potato field utilizing common potato-production practices. The authors acknowledge J.G. Hall and Sons for hosting these trials.

Prior to planting, urea at 120 pounds of nitrogen (N) per acre was broadcast and incorporated. A randomized complete block design with four replicates was utilized. Seed tubers were hand cut to approximately 2-ounce seed pieces prior to planting; an exception was the cultivar Obama, which was planted using whole seed tubers.

Tubers were planted on June 17, 2021, in a single row with 9-inch within-row spacing. Plots were 3 feet wide and 30 feet long.

Stand and stem counts on 10 plants in a row in each plot was taken on July 22. Plant stand was measured on 10 plants on Aug. 9. Vine length was measured on three plants from the base of the plant to the vine tip on Aug. 31. Vigor evaluation was completed on Aug. 31. A rating of 1 indicated least vigor and 5 greatest vigor. Plots were harvested on Sept. 29 and 30 with a single-row plot harvester.

After harvest, potatoes were stored at 55 F° until grading. The tuber size profile distribution was determined by sorting all potatoes harvested into C size (less than 1.875 inches), B size (1.875 to 2.25 inches), A size (2.25 to 3.5 inches) and Chef size (greater than 3.5 inches). Total yield is a summation of C + B + A + Chef.

The 2021 agronomic data presented in Tables 1 through 4 were analyzed statistically. Yield data from 2019 and 2020 are presented as averages and were not analyzed statistically. These analyses allow the reader to ascertain, at a predetermined level of confidence, if the differences observed among cultivars/selections are reliable or if they might be due to error inherent in the experimental process.

The LSD (least significant difference) values beneath the columns apply only to the numbers in the column in which they appear. If the difference between two cultivars/selections exceeds the LSD value at 0.05 or 0.10, it means that with 95% or 90% confidence, respectively, the higher-yielding cultivar/selection has a significant yield advantage. When the difference between two cultivars/selections is less than the LSD value, no significant difference was found between the two under these growing conditions.

The CV stands for coefficient of variation and is expressed as a percentage. The CV is a measure of variability in the trial. Large CVs mean a large amount of variation that could not be attributed to differences in the cultivars/selections.

The data provided does not indicate endorsement or approval by the authors, or NDSU Extension or University of Minnesota Extension. Reproduction of the tables is permissible if presented with all the same information found in this publication (meaning no portion is deleted and the order of the data is not rearranged).

Stand count was taken on July 22 (five weeks after planting) by counting every emerged plant and dividing by the number planted.
Stems per plant were counted on 10 plants on July 22 (five weeks after planting) and are shown as the average number of stems per plant.
Vine length was measured on three plants from the base of the plant to the vine tip on August 31.
Vigor evaluation was completed on August 31 (11 weeks after planting). A rating of 1 indicated least vigor and 5 greatest vigor.
